A network printer could serve many computers so you may not be the only person sending jobs to a printer. In this case it is particularly useful to be able to view the progress of your print jobs as they may be sitting in a queue waiting to be printed. You can also cancel a print job after you have sent it to the printer. Check printers you can access If printing over a network there may be more than one printer you can access. To check the printers that you have access to: 1 Click on Start and then select the Control Panel. 2 Double-click on Printers and Faxes to open this item. 3 In Printers and Faxes you see the names of the computer/s that you should be able to access. 5 Version 2 TPC Janine Ratcliffe 2010 Figure 1: Printers and Faxes (under the Control Panel) where you can see the printer/s you have access to Change the default printer If you have access to more than one printer, then one of those printers will be the default printer. This means it is automatically selected when you send a job to print. In Figure 1 you can see that the default printer has a tick next to it. To set a printer as the default printer: 1 In the Printers and Faxes window right-click on the name or icon of the printer. 2 Select Set as Default Printer from the menu. 6 Version 2 TPC Janine Ratcliffe 2010 Figure 2: Right-click on a printer to select Set as Default Printer—to make this printer the default If you only have one printer available then you will not need to set a default printer. Check printing preferences for a printer Printing preferences include options for printing such as: the size of the paper you are printing to whether the document you are printing has a horizontal (landscape) or vertical (portrait) layout whether you want to print on both sides or only one side of the paper how many copies of the document you want to print. You can change these options every time you send a document to the printer but you can also set default options so that your preferred options are the default until you change them. To check or change the default printing preferences for your printer: 1 In the Printers and Faxes window right-click on the name or icon of the printer. (See Figure 2) 2 Select Printing Preferences from the menu. 7 Version 2 TPC Janine Ratcliffe 2010 Figure 3: The Printing Preferences for Microsoft Office Document Image Writer 3 To change the paper size you want to print on, click on the arrow next to the box under Page size. Select a different paper size from the popup menu. 4 To change the orientation of your document page click in the button next to either Portrait or Landscape. 5 Click OK to save any changes or Cancel to keep the same settings. The preferences box for a printer will have different options depending on the model of the printer, but the basic options shown in Figure 3 should be available for all printers. You can select more printing preferences in a program’s Print box at the time of printing. PRINT DOCUMENTS You can send a document to the printer from the desktop or from within the application program that created the document. Print one or more documents from the desktop To print one or more documents from the desktop: 1 Open a folder that contains one or more documents. 2 Click on the name of the file you want to print. 3 To print more than one file, hold down the Control (Ctrl) Key on your keyboard and keep clicking on files to add them to the selection. 4 When all the files are selected, right-click on one of the selected files. Select Print from the menu. 8 Version 2 TPC Janine Ratcliffe 2010 All the files you selected will be sent to the printer. Print a web page To practise printing a document from within an application program, try printing a page from a website. Your computer needs to be connected to the Internet and have a web browser such as Internet Explorer. 1 Double-click on the Internet Explorer icon on the desktop to open the program. (If your web browser is not on the desktop you may need to open the program from Start then the All Programs menu.) When the browser program is open you will see the Internet Explorer menus at the top of the window. 2 Click on the File menu then select Print from this menu. Figure 4: The Print command is under the File menu 3 The Print box allows you to change the printer and change the printing preferences for the job. (Note that any changes here do not permanently override the default settings.) 9 Version 2 TPC Janine Ratcliffe 2010 Figure 5: The Print box allows you to change print settings and to print from within an application 4 When you have made any changes to the print options click on Print to send the page to the printer or click on Cancel if you don’t want to print the page. You can print a document from within any application program in the same way. That is: 1 Open the document you want to print (Double-click on the filename if it is not already open.) 2 Click on the File menu then select Print. 3 In the Print box check the printing preferences for your job. 4 Click on Print. VIEW THE PROGRESS OF PRINT JOBS If a document is taking a long time to print or the printer is busy with other people’s print jobs, you can check all the jobs that have been sent to a printer and see where your job is in the queue. From the queue you can also delete a print job if you decide you want to cancel it. To view the progress of a print job: 1 Open Printers and Faxes in the Control Panel. 2 Double-click the printer icon to open the print monitor where you can see the jobs currently in the queue for that printer. 10 Version 2 TPC Janine Ratcliffe 2010 Figure 6: Close up of a print queue 3 The print monitor lists the files that have been sent to the printer which are either in progress or waiting to be printed. The order of files in the list is the order they will be printed. Check the Status column (next to Document Name) to see the name of the file that is currently printing. Once a job has printed it will disappear from the queue. 11 Version 2 TPC Janine Ratcliffe 2010 Delete a print job To delete a job from the print queue: 1 In the print monitor window (Figure 6) click on the name of the document you want to delete. 2 Press the Delete key on your keyboard. 3 The following box appears: 4 Click on Yes to delete the print job. Click on No if you do not want to delete it. 5 The word Deleting will appear in the Status column. Note: If you are working over a network, you cannot usually delete the print jobs that some else has sent (as you would not have the permission to do this). Shortcuts to the print monitor Note: if you are not quick enough the document may start to print before you get a chance to delete it. So you may like to use a shortcut to access the print monitor quickly. There may be a shortcut to the print monitor on the Task Bar of your desktop. Otherwise, you can create a shortcut to a print monitor: 1 Open Printers and Faxes in the Control Panel. 2 Click on the printer icon you want to access. Hold down the mouse button and drag the icon to the desktop. 3 A shortcut to the print monitor is now on the desktop. You can double-click this icon anytime to check the print jobs sent to this printer and to delete the jobs you have sent. 12 Version 2 TPC Janine Ratcliffe 2010 START UP AND SHUT DOWN A COMPUTER Inside this resource Identify the parts of a personal computer 13 Input/output/process 14 Input 15 Process 16 Output 16 Examples of input/output/process 16 Identify common peripheral devices 18 Software for personal computers 20 Operating systems 20 Application software 20 Starting a computer running Windows XP operating system 21 Sequence for starting a computer 21 Logging on 22 Shutting down a computer running Windows XP operating system Logging off 22 23 Sequence for shutting down a computer 24 IDENTIFYING THE PARTS OF A PERSONAL COMPUTER There are many different models of personal computers. They include desktop personal computers (PC), notebooks and laptops but they all have the same basic hardware parts: a keyboard mouse/touch pad/trackball monitor (screen) system unit. 13 Version 2 TPC Janine Ratcliffe 2010 The diagram below shows a typical set up of a personal computer. Figure 1: The typical set up of a personal computer Another type of personal computer is a notebook. A notebook is a compact computer that is easily transported and can be powered by batteries. Figure 2: Notebook computer Next time you see a shop that sells computers you could have a look at some of the computers, notebooks, laptops and palm pilots that are available. INPUT/OUTPUT/PROCESS The computer system needs people, data, hardware and software to operate. The process for getting data in, processing the data and getting the information out is known as input/process/output. 14 Version 2 TPC Janine Ratcliffe 2010 Input Input is the data that is entered into the computer. It is entered through input devices. Some examples of input devices are: mouse keyboard microphone scanner digital camera joy stick touch pad MP3 player digital video player (plays DVDs). Using a mouse (input device) The mouse is used to move the mouse pointer around the screen and to perform tasks such as moving and opening folders or files. A mouse could be attached to a computer with a cord or it may be cordless (a remote mouse). You see the position of the mouse on the screen by seeing a symbol. The mouse symbol moves around the screen as you move the mouse. Depending on the task you are doing, the mouse symbol could look like any of the following. A mouse pointer: means you can click on an item, such as a folder icon, to select it or move it. A timer: means the computer is busy processing a task so you need to wait until the computer finishes the task and the symbol changes back. Flashing insertion point: When you click the mouse the insertion point will flash if text can be entered or deleted. I I-beam: This shows you where your mouse is when it is hovering over text. Check your computer to see what input devices you have available. List them here: Next time you see a shop that sells computers you could have a look at some of the other input devices that are available. 15 Version 2 TPC Janine Ratcliffe 2010 Process Processing refers to the computer performing operations and calculations (using the data that has been input and software). This processing of data is done by the central processing unit (CPU) that is housed in the system unit. Output Output is what the computer displays as a result of processing data (eg calculations or instructions). Some examples of output devices are: printers speakers monitor/screen. List the output devices that your computer has: _________________________________________________________ Next time you see a shop that sells computers you could have a look at some of the other output devices that are available. Figure 3: A computer with typical input and output devices Examples of input/output/process The table on the next page gives some examples of input/process/output. Can you think of another two examples to add in the last two rows of this table? 16 Version 2 TPC Janine Ratcliffe 2010 Table 1: Examples of input/process/output Activity Input Process Output Getting money at the Automatic Teller Machine (ATM) Swipe card and enter PIN number. Computer checks the PIN number is valid for the card you used. Options to continue or ‘Access denied’ is displayed on the terminal screen. Enter the account you want to withdraw the money out of. The bank’s computer checks whether you have enough money for the transaction. If you have enough money you get the money plus a receipt. Prices and details of item from barcode on the goods Computer adds up the items and provides a total cost. Details of goods including price/weight come up on screen. Pay for goods. Computer checks your payment methods and calculates any change required A receipt is printed and message on screen gives change amount. Preparing a travel budget Data is entered that lists expected costs. The computer calculates the total costs. The result is shown on the computer screen and it can be printed. Print a label for a customer order Select customer name and address from file. Computer checks the printer is ready and sends label details to the printer. Label is printed by the printer. Buying groceries 17 Click on Print. Version 2 If you don’t have the money you get a message that denies the transaction. TPC Janine Ratcliffe 2010 IDENTIFYING COMMON PERIPHERAL DEVICES Peripheral devices are items of hardware attached to the main computer that allow you to perform tasks such as printing, copying, connecting to the Internet and scanning. Some examples are a: printer scanner external disk drive memory stick. Printer (output device) Printers can provide ‘hard copies’ or printouts of information on documents or web pages (at various sizes, colour or black and white, depending on the printer). Some printers are also designed especially for printing photographs, or CD labels straight onto the CD. Scanner (input device) A scanner is a device that lets you take a copy of a document or image. You might want to copy a photo, a picture from a book, a plan, etc. 18 Version 2 TPC Janine Ratcliffe 2010 Your computer List all the peripheral devices connected to your computer and any others you would like to connect to your home computer: _________________________________________________________ _________________________________________________________ _________________________________________________________ 19 Version 2 TPC Janine Ratcliffe 2010 SOFTWARE FOR PERSONAL COMPUTERS A computer cannot operate (or process data) without sets of instructions. These sets of instructions are called programs or software. The two main types of programs are operating system software and application software. Operating systems An operating system is a program that controls the operation of software applications and hardware. The operating system is like the captain of a team. That person controls the gameplay of all the team members to achieve a desired outcome. Examples of operating systems for personal computers include: Windows XP or Vista Mactintosh OSX. When you start up a computer the operating system will automatically launch and many display a ‘desktop’ environment. The operating system will allow you to navigate around the data stored on the computer and change settings such as colours, the date or the way that data is displayed—to suit your preferences. Application software Software programs enable users to undertake specific tasks like creating: word processed documents page layouts spreadsheets databases. Each of the above tasks would require a dedicated software application, for example Microsoft Word is used for word processing. Applications can be bundled together as a software package. A package is a suite of applications that ‘talk’ to each other so that data created in one application (eg a word processor) can be exported to another for performing calculations on that data (eg to a spreadsheet). This type of bundling is called an integrated package. 20 Version 2 TPC Janine Ratcliffe 2010 STARTING A COMPUTER RUNNING WINDOWS XP OPERATING SYSTEM Starting your computer is also known as booting the computer. It is important to switch your computer on in the correct way because the computer will check the peripheral devices on start up. Starting the computer will also start the operating system. Figure 4: If the power switch on the system unit is off (no light), then you need to turn on the computer parts in the correct sequence Sequence for starting a computer 1 Check peripheral device connections. 2 Turn on power at the power outlet. 3 If the monitor has a separate switch, turn it on. 4 Switch on the printer. 5 Check to see if there is a floppy disk in the floppy disk drive if your computer has one. Eject the disk to ensure the computer starts from the hard drive. 6 Switch on the system unit. If using a desktop PC the power switch is usually a button on the front or side of the system unit. If using a laptop the power switch is usually at the top of the keyboard. 7 The computer will perform a start-up routine. When the start-up routine has completed then the operating system will start. 21 Version 2 TPC Janine Ratcliffe 2010 Logging on The computer you are using may have been set up so that you need to log on to the computer in order to be able to access the software and stored data, and commence using it. This is a security feature that is often in place for computers in the workplace, school, college or other large organisation. When you log on you are connecting the computer with a network of other computers in the organisation. If you need to log on you will see a box on the screen asking you for two items of information that you need to type in: 1 username 2 password. Usernames and passwords are set (for each authorised user) by the IT Administrator for the organisation. Your teacher or IT Department (in an organisation) will provide you with these details. Security conditions Your username and password determines what information and features of the computer and network you have access to, and this is determined by the IT security policy of the organisation. Therefore, it is important to note the conditions of use that apply to you when you log on to a computer with your username and password. These conditions appear on the screen before you are asked to enter your name and password. You must click on the OK button after you have read the conditions. This enables you to get to the log on screen where you enter your name and password. SHUTTING DOWN A COMPUTER RUNNING WINDOWS XP OPERATING SYSTEM It is good practice to use the correct shut down procedure when you want to turn off your computer so that you do not lose data. If you still have any software applications or files open they will be displayed at the bottom of the screen. Each of the applications and files must be closed. You may get a message asking you to confirm whether files need to be saved. Make sure you save any work you have done before you turn off the computer. Depending on whether or not you have had to log on to start using a computer, you will need to follow a different sequence shutting down the computer. 22 Version 2 TPC Janine Ratcliffe 2010 Logging off If you have had to log on to the computer when you started the session, then you need to log off when you finish your session on the computer. Logging off means you are disconnecting the computer from the network and no one else will be able to access the same computer unless they also have a log on (username and password). You must log off the computer regardless of whether or not you will be turning off the power. If you don’t log off the computer, then you will be preventing other people from using the same computer and being able to log on with their own name and password. In the workplace, failure to log off will probably also mean that other people (who may be unauthorised to use your computer) can access all the files that you have access to. This could mean a serious breach of security in an organisation. To log off a computer: 1 Close all files (remember to save your latest work if necessary). 2 Close all software programs. 3 Remove floppy disks or other storage media from drives if necessary. 4 Click the Start button on the taskbar (at the bottom left corner of the screen) to see the Start menu. 5 Click on Log Off (at the bottom of the menu). 6 A message box will appear on the screen asking you to confirm that you want to log off. Click on Log Off. 7 A final message box will appear telling you ‘It is now safe to turn off your computer.’ You can now switch off the computer and the power outlet if you want to shut down the computer. Figure 5: Logging off in Windows XP. From the Start menu, click on the Log off button at the bottom of the menu. Figure 6: A box appears asking you to confirm that you want to log off. Click on the Log Off button to confirm. 23 Version 2 TPC Janine Ratcliffe 2010 Sequence for shutting down a computer Follow this sequence if you do not have to log off first. 1 Close all files (remember to save your latest work if necessary). 2 Close all software programs. 3 Remove floppy disks or other storage media from drives if necessary. 4 Click on Start on the taskbar. Select Turn Off computer from the Start menu. 6 Check that Turn off is selected. 7 Click on OK to confirm. Your computer may automatically turn the power off but if not you will get a message like ‘It is now safe to turn off your computer.’ 8 Switch off the computer and the power outlet. 24 Version 2 TPC Janine Ratcliffe 2010 ORGANISE FOLDERS AND FILES ON A COMPUTER Inside this resource How data is typically stored on a home or office computer Storage devices 25 26 Access directories and sub-directories 27 Access directories on your computer 28 Change the view of a directory 28 Access files you use regularly 30 Identify attributes of directories 30 Move and rename directories 31 Move subdirectories between directories 32 Copy, cut and paste files across directories 32 Rename directories 33 Select, open and rename groups of files 33 Create directories and sub-directories 33 Delete and restore files 34 Delete files and folders 34 Restore deleted files 35 Empty the Recycle Bin 35 Use the search tool to find specific files 35 Copy files to a disk 37 Erase and format a floppy disk 38 HOW DATA IS TYPICALLY STORED ON A HOME OR OFFICE COMPUTER Data files such as word documents can be kept on a computer for future uses such as editing and printing. To find documents you will need to store them in an organised fashion—in the same way you might file documents like lesson notes, bills, letters and bank statements at home. Just as you might use folders to organise your personal or business documents, you also store your computer documents in folders. A folder is only a device for grouping files in the same location, not a data file. Folders and files can be stored on a computer’s desktop or on a storage device which will be able to store hundreds or thousands of documents. 25 Version 2 TPC Janine Ratcliffe 2010 Folders can be created or moved so that they sit within another folder, and so on. Other terms for describing this structure of files and folders grouped within folders are directory and subdirectory. In this reading we’ll look some examples of directories so that you can find specific folders and files on a computer and create your own folders to store and organise documents. First, though, you will need to decide where you want to save files. There are several types of storage devices that may be an option for you, depending on your computer setup. Storage devices Hard disk drive (HDD) Your computer will have a hard disk drive. The hard disk drive is in the system unit. The hard drive is where the operating system and application programs are kept. If you are using a Microsoft Windows operating system there is also a location called My Documents on the hard drive for storing your data files. You can also have a removable hard disk drive which has the advantage of being able to store a large amount of data and be transported and connected to other computers. Floppy disk drive (FDD) A floppy disk is the least expensive storage media. They don’t hold a lot of data but they are easily transportable. They can be damaged by smoke, heat, magnets and liquid. Memory stick/flash drive/thumb drive/pen drive/USB drive All these terms refer to a small drive that you plug into a USB port (an input connection on the system unit). They are small (about the size of a disposable lighter) and can be carried easily. They hold a lot more data than a floppy disk. CDs (compact disk) CD-R: (compact disk read-only) are read-only format which means you can read the data but you can’t write (add) data to the CD. They often have application programs or music stored on them. CD-RW: (compact disk read-write) another form of CD that you can read and write to. This means you can add or copy data to this type of CD. You will need a CD burner to do this. 26 Version 2 TPC Janine Ratcliffe 2010 ACCESS DIRECTORIES AND SUB-DIRECTORIES Figure 1 shows a view of the directories and sub-directories (folders) that are stored on a floppy disk. Figure 1: When the Customers folder is selected in the left frame its sub-folders are listed in the right frame In Figure 1 the 3½ Floppy (A:) drive contains three folders: 1 Customers 2 Staff 3 Warehouse. The Customers folder has four sub-folders: 1 CD Basement 2 Gig Shop 3 MP3 to go 4 Music Beat. 27 Version 2 TPC Janine Ratcliffe 2010 Access directories on your computer You can view folders on a drive and the contents of the folders through windows. Doubleclicking on a drive icon or a folder icon opens a window which shows you its contents. Try this exercise: 1 Double-click on the My computer icon on the desktop. 2 Double-click on a data drive (check with your teacher or someone familiar with your computer which drive is a data drive if you are not sure). 3 You will see a list of folders stored at the root level of the drive. Double-click on a folder to view the contents of the folder. 4 Keep opening folders until you find files inside a folder. Note the difference between icons for folders and files (see Figure 2). Figure 2: One folder and three files are contained in this folder Change the view of a folder’s contents You can choose a different view (appearance) of the contents of a folder depending on what is useful for you. 1 Click on the View menu of a window. 2 Select a view from the menu (Thumbnails, Icons, List, Details). Try each of these to see the different views. View a directory tree structure Files and folders can be enclosed by any number of folders which creates a hierarchy or tree structure. You can change the view of a folder window to see the directory tree structure. 28 Version 2 TPC Janine Ratcliffe 2010 This allows you to see the whole directory structure as well as the contents of any folder in one view. An easy way to view the directory tree is to click on the Folders button on a window Toolbar (see the window Toolbar in Figure 2). If you can’t see the Folders button on the Toolbar, click-drag the right edge of the window to expand the size of the window and its Toolbar. When you click on the Folders button the directory tree will appear in the frame on the left. When you click on a folder its contents are listed in the right frame (see Figure 1 and Figure 3). Figure 3: The folder CD Basement is selected in the left frame so that its contents can be viewed in the right frame In the left frame you can click on the + sign next to a folder to expand the folder—this will also show you the contents of the folder (listed in the left frame) under the folder. Click on the - sign next to a folder to contract the folder (to hide the contents of the folder). To change the window view back to the original view click on the Folders button again. 29 Version 2 TPC Janine Ratcliffe 2010 Access files you use regularly There may be files that you regularly need to access, for example, to update a database or use a document template. In Microsoft Windows you can create shortcuts to files so that you can quickly access them under the Favourites menu. To do this: 1 Use any of the above methods to find the file you regularly use. 2 Click on the file name to select it. 3 On the window Toolbar click on the Favourites menu. 4 Click on Add. You can now access the file from the Favourites menu (on any window’s Toolbar) by clicking on Favourites and selecting the file. IDENTIFY ATTRIBUTES OF DIRECTORIES Attributes define the type of file or directory which could be: read-only hidden archive system. Sometimes you will need to check the attributes of a file or folder to ensure you use it appropriately. Or you may wish to set attributes to read-only so that data is not lost or changed by someone. To check or change the attributes of a file: 1 Double-click on My Computer on the desktop. 2 Double-click on a data drive and find a document file. 3 Right-click on the file you want to check. 4 Select Properties from the menu. 30 Version 2 TPC Janine Ratcliffe Figure 4: The Properties box for this file shows that the file is Read-only 31 Version 2 2010 TPC Janine Ratcliffe 2010 MOVE AND RENAME DIRECTORIES Move subdirectories between directories Sometimes it is necessary to move a folder to another location or folder. Here are two ways you can do this. (Note that you can move a file in the same ways.) Use ‘Move To Folder’ 1 In a window view, click once on the folder you want to move (so that it is selected). 2 In the window’s Toolbar click on the Edit menu and select Move To Folder. 3 Select the folder you want to move the selected folder to. To do this, scroll up or down the list to find the target folder. You may also need to expand folders to find the folder you want. To select the target folder click on the folder name so that it is highlighted. 4 Click on the Move button. Drag the folder to the new location Another way to move a folder is to drag the folder to the new location: Click on the folder icon and keep the mouse button down as you drag the folder over the top of the target folder. Release the mouse button when the target folder is highlighted. Click-drag the folder into the window area of an open folder or drive window. Copy, cut and paste files across directories OR Cut, Copy and Paste are tasks you can do in all application programs and windows such as a folder or drive window. You need to make a selection first so that you can cut or copy the selection and then paste it in another location. With cut, copy and paste you can remove or move a folder or a file as follows: Cut: Remove file from current location. Copy: Make a copy of the file. Paste: Place a copied or cut file into another location. Try this exercise: 1 Locate a file to move to another location (such as a different folder). 2 Right-click on the file to select it. 3 Select the appropriate option: Cut or Copy. 4 Open the directory or folder where the file is to be moved. 5 Right-click anywhere in the window where you want to paste the file. Click on Paste in the menu. 32 Version 2 TPC Janine Ratcliffe 2010 Rename directories You can rename your folders at any time. To do this: 1 Right-click on a folder. 2 Left-click on Rename in the menu. 3 Type in the new folder name. 4 Press Enter on the keyboard to save the change. Select, open and rename groups of files Sometimes you may wish to select, open or rename more than one file at a time. Select and open more than one file 1 Hold down the Control key (CTRL) and click on each file you want to select. Don’t release the Control key until all the files are selected. 2 Right-click on one of the selected files and select Open from the menu. To rename more than one file 1 Select the files to be renamed as you did in step 1 above. 2 Right-click on one of the selected files and select Rename from the menu. 3 Type in the new file name. Note: Windows will give each file a number after the common file name. CREATE DIRECTORIES AND SUB-DIRECTORIES You can set up your own directory and sub-directories by creating new folders within a hierarchical structure, depending on a logical or business system for organising the directory. In our earlier example (Figures 1 and 2) the directory on the floppy disk has this hierarchical structure: Figure 5: The hierarchical structure of the directory in Figures 1 and 3 33 Version 2 TPC Janine Ratcliffe 2010 To create a new folder: 1 Locate the directory or folder in which you want to create a new sub-directory/folder. 2 Double-click on this folder to open it. 3 In the folder window click on the File menu and select New then Folder. This creates a new (empty) folder inside the folder you have opened. 4 Type in the name of the new folder (to replace the default text ‘New Folder’.) To create more folders at the same level as this, keep selecting New Folder until you have all the folders you need. To create one or more folders inside one of the new folders, repeat the above steps. In this way you can create a hierarchy of folders according to a hierarchical structure. The new directory will be set up and ready to save or copy any documents into. DELETE AND RESTORE FILES Delete files and folders You may need to delete files or folders, for example, when you no longer need them or when they are copied to another disk. Here are two ways you can delete a file (a folder can be deleted in the same ways). Right-click on the file you want to delete 1 Right-click on a file. 2 Left-click on Delete in the menu. The file is now moved to the Recycle Bin which sits on the desktop. Drag the file to the Recycle Bin Another way to delete a file is to drag it to the Recycle Bin on the desktop: 1 Click on the file and hold the mouse button down as you drag it to the Recycle Bin. 2 When the file is directly on top of the Recycle Bin the bin will be highlighted. At this point release the mouse button and the file will be moved into the bin. Figure 6: Icon for the Recycle Bin in Windows XP 34 Version 2 TPC Janine Ratcliffe 2010 Restore deleted files If you have deleted files or folders but not emptied the Recycle Bin you can still get the deleted files back. This is called restoring a file. To do this you need to access the Recycle Bin from the desktop: 1 Double-click on the Recycle Bin to open it. Inside this window you can see the files that have been deleted. 2 Right-click on the file you want to restore. Click on Restore in the menu. The file will be returned to the place it was previously deleted from. Empty the Recycle Bin Deleted files and folders stay in the Recycle Bin until you empty the bin. If you empty the Recycle Bin anything in it will be permanently deleted (unable to be restored from the desktop). It is a good idea to empty the Recycle Bin on a regularly basis, as deleted files take up storage space on the computer. To empty the Recycle Bin: 1 Right-click on the Recycle Bin icon. 2 Select Empty Recycle Bin from the menu. (If there are no files in the bin then this option will be faded.) The files that were previously deleted (transferred to the bin) are now permanently deleted. USE THE SEARCH TOOL TO FIND SPECIFIC FILES Sometimes files are saved or moved to locations that you can’t remember or just don’t know. There may be thousands of folders in a hard drive which would be impossible to browse in order to find a lost file. Luckily there is search tool that is part of a computer’s operating system. This tool runs an automatic search on a drive or within a specific directory (using keywords or the file name) to find a file or folder. You can open the Search Companion (the search tool in Microsoft Windows) in a number of different ways—here are three ways to do this. Right-click on a folder or drive icon 1 Right-click on a folder or drive icon and select Search from the menu. This will search on the folder or drive you clicked on, eg My documents. 2 Type in either part or all of the file name OR a word or phrase contained in the document you are searching for. 35 Version 2 TPC Janine Ratcliffe 2010 Figure 7: Microsoft Windows Search Companion 3 Click on the Search button. 4 The results of the search are listed in the window. There may be more than one result for your search. Double-click the correct file to open it, or move the file to another location. Figure 8: Results of a search 36 Version 2 TPC Janine Ratcliffe 2010 Press the F3 Key Alternatively, from the desktop press the F3 key on the top row of your keyboard. You may need to select the specific folder or drive you want to search on. Go through the Start menu Another way to access the Search Companion is to click on Start and select Search from the Start menu. Click on the Files and Folders link to go to the same search box as shown above. You may need to select the specific folder or drive you want to search on. Search a different directory The search will be done on whatever folder is selected in the Look in: field. To search a different directory, click on the arrow next to the Look in: field to get a menu of all the drives you have access to. Scroll down to the very end of this list and select Browse. Then you can search the directory tree to find a specific folder to search. Click on the name of the folder you want to search and then click OK. Advanced searches You can do an advanced search to look for files used in the last week or month when searching files and folders in the Search Companion box. 1 Click on More Advanced Options 2 Select the appropriate setting for your search. 3 Click on Search. COPY FILES TO A DISK Copying files means that you can leave the files in their current location and place copies in another location. For example, you can copy a file from the hard disk and save it on a floppy disk or flash drive. Here are two ways you can do this. Copy and Paste a file 1 Locate the file you want to copy. 2 Right-click on the file. Click on Copy in the menu. 3 Right-click in a new location. Click on Paste in the menu. Drag a file from one disk to another When you drag a file or folder from one disk or storage media (such as a hard disk) to another (such as a flash drive), a copy of the file or folder is automatically made at the new location. When you do this, make sure you have the destination folder or drive in view—in a window or on the desktop. 1 Click and hold down the mouse button on the file you want to copy. 2 Drag the file to the destination. If you drag the file on top of a closed folder and release the mouse button then the file will be copied inside that folder. 37 Version 2 TPC Janine Ratcliffe 2010 ERASE AND FORMAT A FLOPPY DISK You can format a disk if you want to erase the contents of the disk. You might want to do this because you no longer need the data that was stored and you want to reuse the disk. You might also want to format the disk if it has a virus. To format a floppy disk: 1 Place a floppy disk in the floppy disk drive. 2 At the desktop double-click on My Computer to open it. 3 Right click on 3½ Floppy (A:) drive. 4 Click on Properties in the menu. 5 Click inside the Volume Label box and type in your name. 6 Click the checkbox for Quick Format to select this. 7 Click on Start. 8 Click on Close when the formatting is complete.

A computer desktop can display shortcuts to get to application programs and storage devices (such as the hard drive). You can also create your own shortcuts to places on a hard drive or network, so that you can open particular websites or files and folders quickly. All these shortcuts are displayed on the desktop as icons. There are different styles of icons depending on what they represent (although later you find out how you can change an icon graphic to suit your preference). To go to the shortcut, you double-click on the icon. Icon for Internet Explorer. Doubleclick this icon to 39 Icon for accessing shared files on a network.

Double-click this icon to go to open the folder 2010 icon to go to the website Figure 1: Different styles of icons you might find on the desktop The desktop loads after you start up a computer that is running a windows-based operating system like Microsoft Windows XP or Macintosh OSX. If you are using a Microsoft Windows operating system you will see the Start button (to get to the Start menu) on the bottom left and some desktop icons. CREATE DESKTOP ICONS/SHORTCUTS Now try customising your own icons/shortcuts on your desktop. For the following examples, the operating system Windows XP is used. We will practise two ways of creating a desktop icon: 1 Click and drag an item from a menu. 2 Use the Create shortcut command in a window’s File menu. Create a desktop icon to open the Control Panel Follow these steps using your own computer. 1 Click on Start on the Task Bar. 2 Click on the menu item Control Panel but keep the mouse button held down and drag the mouse pointer from the Control Panel to the Desktop. 3 The following icon will now be on your desktop: You have now created a desktop item which will allow you to open the Control Panel from the desktop instead of going through the Start menu. Create a desktop icon to open a program 1 Click on Start on the Task Bar. 2 Click on All Programs. 3 Under All Programs, click on Accessories. 4 Under Accessories, click on Paint and drag this item to the desktop. (If you don’t have Paint on your computer then select a different program.) 5 You should now have an icon/shortcut to the program on your desktop. 40 Version 2 TPC Janine Ratcliffe 2010 Create a desktop icon to open the DVD/CD drive You can also place shortcuts to storage media drives on the desktop. You would do this if you are regularly using these items. 1 Double-click on My Computer (on the desktop). 2 Click DVD/CD Drive and drag this item to the Desktop. 3 The following icon will now be on your desktop: Create a desktop icon to open a folder When you have a lot of folders stored on the computer, shortcuts to folders you regularly use are very handy. 1 Double-click on My computer (on the desktop). 2 Double-click on one of the drives listed under Hard Disk Drives. You will now see a list or group of folders that are stored on that drive. 3 Click once on one of the folders stored on the drive. The name of the folder will now be highlighted (which means it is selected). 4 Click on the File menu at the top of the window and move down the menu and click on Create Shortcut. (See Figure 2.) 41 Version 2 TPC Janine Ratcliffe 2010 Figure 2: Create Shortcut under the File menu 5 A new folder called ‘Shortcut to…(the name of the folder)’ appears in the window. Click and drag this shortcut item to the desktop. 6 The following icon will now be on your desktop (but with a different folder name): CUSTOMISE THE APPEARANCE OF ICONS Rename an icon You can rename any icons on the desktop such as a shortcut to a folder. 1 Right-click on the icon you want to rename so that a menu appears. 2 Move the mouse down the menu and select Rename. The name of the icon is now highlighted (which means it is selected). 42 Version 2 TPC Janine Ratcliffe 2010 Figure 3: Right-click on an icon to rename or delete an icon 3 Use the keyboard to type the new name for the icon. The text that you type will replace the highlighted text. 4 Press Enter on the keyboard OR click anywhere on the desktop to save the new name. Delete a shortcut/icon You can delete a shortcut when you no longer need it. Note that if an icon is actually the file to open a program, and not just a shortcut to it, then you probably don’t want to delete this! Delete the shortcut to the DVD/CD drive: 1 Right-click on the DVD/CD icon/shortcut so that a menu appears. 2 Click on Delete. 3 Click on Yes to confirm you want to delete this icon. The desktop icon/shortcut for the DVD/CD drive will be deleted but you will still be able to access the drive through My Computer. Only the shortcut has been deleted. Change the picture for a shortcut/icon You can change the picture for a shortcut/icon by selecting from a range of icons provided by the operating system. 1 Right-click the shortcut/icon you want to change so that a menu appears. 2 Click on Properties. 3 Under the Shortcut tab, click on Change Icon. (See Figure 4.) 43 Version 2 TPC Janine Ratcliffe Figure 4: Changing the picture for an icon 4 Click on the icon picture you want then click the OK button. (See Figure 5.) 44 Version 2 2010 TPC Janine Ratcliffe Figure 5: The globe icon is selected for My photos shortcut Change the size of icons You can change the size of icons and the text related to the icons. 1 Right-click on an empty area of the desktop—not on an icon. A menu appears. 2 Click on Properties.

If you want to make the changes, note the original settings (so that you can return and put the sizes back to their original settings). ARRANGE ICONS ON THE DESKTOP When you have a lot of icons or shortcuts on the desktop you may want to organise them according to either: Their name (alphabetical order) Their size (the amount of data that the icon points to) Their type (group icons for files made with the same program) When they were modified (group the icons according to when they were last customised). When you arrange the icons according to any of the above preferences they will regroup on the desktop and be laid out in rows (if Align to Grid is also selected). Arrange icons on the desktop 1 Right-click on an empty area of the desktop—not on an icon. A menu appears. 46 Version 2 TPC 2 Janine Ratcliffe 2010 Click on Arrange Icons By, then from the sub-menu choose your preference. (See Figure 6.) Figure 6: Arrange Icons By sub-menu showing preferences for how icons can be arranged on the desktop (with Align to Grid selected) SELECT, OPEN AND CLOSE DESKTOP ICONS TO ACCESS APPLICATION PROGRAMS You can now open an application program from the desktop icon. Click on the icon/shortcut for Paint (or another program you have made a shortcut to) to open the application. To close this application click on the Close button at the top right of the window. Try opening some other items on the desktop. Remember to close them when you have finished. Notice that any items you open will appear on the Task bar at the bottom of the screen. You will need to close all of these items before you shut down the computer. 47 Version 2 TPC Janine Ratcliffe 2010 ACCESS BASIC SYSTEM INFORMATION Inside this resource Getting familiar with the desktop environment 48 Using the mouse 48 What is the desktop? 49 Desktop windows 49 The task bar 50 The Start menu 50 Accessing system information and settings 51 The Control Panel 51 Customise the desktop 52 Change the date and time 55 Check printers and faxes 56 Open and close an application program 58 Getting online help 59 Using online help in Windows XP 60 Getting online help in an application 62 GETTING FAMILIAR WITH THE DESKTOP ENVIRONMENT Using the mouse One of the most useful tools for working on a computer is the mouse. The mouse is used to move a pointer or cursor around the screen, in order to select a button or icon to perform a particular task, or to access, move or copy data. When you create your own files using application software (like a word processor) you’ll use the mouse to help you write and edit text or other data. So before you start to navigate around the computer, make sure you are comfortable with using the mouse. It may take some time and practice to get this. Practice moving the mouse Mouse pointer: On the screen, the mouse usually appears as a small white or black arrow. When you move your mouse on a flat surface, the arrow will match the movement on the screen. To move the mouse pointer, move the mouse across the mouse pad and watch the pointer on the screen move in the same direction. Practice moving the mouse now. 48 Version 2 TPC Janine Ratcliffe 2010 Doing tasks with the mouse There are a variety of mice available. Apple computers have a single button, while PCs can have either two buttons (a left and a right button) or three buttons (left, middle, right). The left and right mouse buttons, however, are commonly used by PC operating systems. Some common ways that you can use a mouse with two buttons include: Left-click: One click of the left mouse button allows you to choose something on the screen. Right-click: One click of the right mouse button will often open up a shortcut menu. Double-click: Quickly clicking the left button twice allows you to open a selected file or folder. Click-drag: Left-click on an item, such as a file icon, and keep holding the mouse button down, then drag the item to move it to a new location. Another common function that click-drag performs is with text. For example, when you are inside a word document, leftclick at the start of a sentence and drag to the end of the sentence to select that sentence. Figure 1: A mouse with two buttons and a scroll wheel A mouse may also have the additional feature—a scroll wheel—that enables you to use the mouse to scroll up and down a window instead of using the window’s scroll bars. What is the desktop? The desktop is the background screen that appears as soon as the computer has finished starting up. The desktop is part of the operating system software, so its appearance is controlled by system settings. There are several useful items on the desktop including: Icons: An icon is a small picture that may appear on your desktop. Double left-clicking on an icon is an easy way to open a program, files or other items (such as storage drives). Icons allow you quick access to all of these items. Desktop windows It is very important to become familiar with how to work with windows on the computer. A window is an area on the screen that displays programs or information. For example, windows are a device the operating system uses to display a list of the contents of a folder. A 49 Version 2 TPC Janine Ratcliffe 2010 window can be moved, resized, opened and closed. Many operating systems allow you to have several windows open at any time, so you can easily move around between areas. Windows are also used in application programs to display a document when it is open. There are several features of windows including: Title bar: This is a bar that appears at the top of the window. It often includes the name of the program or folder. Minimise: This option shrinks the window to its smallest size. It will now only appear as an option on the task bar. The program is still open; left-clicking on it in the taskbar will restore it to its regular size. Maximize: This options makes the window expand to its largest size. Close: This will close the window. If you need to save your work, a program will usually ask you to save before closing. Scroll bar: This is a slider on the right-hand side of the window that allows you to move down the contents of the window, in the same way you might have scrolled down a website page. Left-click and drag the slider, or left-click on the down and up arrows in order to move up or down the window contents. Minimise Maximise Close Figure 2: Buttons that appear in Microsoft Windows operating system windows—to minimise, maximise and close a window. These buttons sit at the top right-hand corner of every window. The task bar The Task bar is a horizontal bar at the very bottom of the desktop. It shows any applications or windows that are open. If there is more than one document open in an application it will show the name of the application and the number of files open. It also shows the time and short cuts for any other items open on the desktop. The Start menu You can left-click the Start button on the Task bar to see the Start menu. This menu allows you to: access information about the computer system you are using access controls for changing the way that information is displayed access application programs that are installed on the computer. Next we’ll look at the settings you can access in the Control Panel. The Control Panel can be selected in the Start menu. 50 Version 2 TPC Janine Ratcliffe 2010 Figure 3: The Start menu where you can access system information and change display settings (in the Control Panel), and open the application programs ACCESSING SYSTEM INFORMATION AND SETTINGS The Control Panel The Control Panel enables you to view and change settings to things like: The display—screen savers, patterns, appearance, wallpapers. Date and time The system—resources that the system has available such as devices listed in the hardware tab. Printers and faxes—shows printers and faxes and their settings. There are other options that you could use once you are more confident. The Control Panel window contains many icons that represent different controls, players or information about the computer system. You can access any of these by double left-clicking on an icon. Look at Figure 4 on the next page. Find the icons for: 1 Date and time 51 Version 2 TPC Janine Ratcliffe 2 Display 3 Folder options 4 Printers and Faxes. 2010 Figure 4: The Control Panel window where you can access information and system settings by double-clicking on the icons Customise the desktop It is possible to customise your desktop, for example, to change the background pattern and the style of the text displayed by the operating system.

These may be program files which are required by the computer to operate or data files which contain the information you create when you type letters, posters, calendars and so on. Files need to be saved so that they can be used at a later date, that is you need a pathway or location to find the file. When you save a file you need to choose the drive and directory into which the file is to be stored. You can think of drives as drawers in a filing cabinet and directories as the labelled folders in the filing cabinet. Many of you will have used the A drive, so your files have been stored in the A drawer. Drives are identified with letters. A is used for the floppy drives, while C is used for the primary hard disk. A CD-ROM drive is commonly accessed as D, whilst a removable drive is the E drive. 66 Version 2 TPC Janine Ratcliffe 2010 FILES AND FOLDERS When we type a document we give it a relevant file name and save it, for example, resume 2005 on the 31/2 Floppy (A:). Really what we are doing is create a filing system for our documents. Create a Document Save as a file (file name) Save in a drive Save in a folder Most of you in the class have been saving documents to your 31/2 floppy (A:) drive, so you are already able to file your documents.

Type the article on the following page “Handling and storing your disks, CDs and DVDs” in Arial 13. 68 Version 2 TPC Janine Ratcliffe 2010 Handling and storing your disks, CDs and DVDs Guidelines for handling your disks, CDs and DVDs 1. Handle disks by the outer edge or the centre hole only, do not touch the surface of the disk. Disks should not be bent or flexed. 2. Do not write or mark in the data area of the disk (the area the laser reads). Write on the clear ‘hub’ area of the disk or, preferably, on the packaging that contains the disk. 3. If you must label the disk itself, use a water-based felt-tip permanent marker to mark the label side of the disk. Do not use adhesive labels as the adhesive can damage the disk. 4. Keep dirt or other foreign matter away from the disk. 5. If a disk is dusty take great care and gently remove loose dust using a non-abrasive photographic lens tissue, or very soft brush. Oily dirt deposits and finger marks can be removed using CD/DVD-cleaning detergent, isopropyl alcohol, or methanol. The solution should be applied sparingly to the disk surface and wiped off with a tissue. The cleaning motion should never be circular (along the tracks). Always brush from the centre of the disk outwards. 6. Store disks in their packaging (or cases) to minimise the effects of environmental changes. Remove a disk from its protective packaging only for use and return it immediately after use. 7. CDs should not be stacked or packaged in groups so that they lean against each other. The pressure may lead to warping or deformation. Store disks upright (book style) in plastic cases designed for CDs and DVDs. Disks stored horizontally for a long time (years) can warp. 8. Optical disks should be stored at temperatures between 4°C and 20°C and relative humidity (RH) 20 to 50%. For longterm storage, 18°C and 40% RH is suitable. 9. Do not expose disks – especially recordable ones – to prolonged sunlight or other sources of ultraviolet light. 8. Save the document as “Handling CDs & Disks” to your 3 ½ Floppy (A:) Disk. 69 Version 2 TPC Janine Ratcliffe 2010 9. Resave (save again) your document to your personal folder in My Documents.

If you have a personal computer at home most of your programs and information is stored in the hard drive or C drive. The 31/2 floppy drive is the A drive and if you have a CD drive it is usually listed as a D drive. A removable drive or any other drive is usually an E drive. The TAFE system is a little different as it has many drives. It operates off the C drive the same as a personal computer but also has many other drives for different functions. Students can access some of these drives. In this session we will be using the J drive which is the public student drive that is stored on a server in Sydney. The J drive and all of its files can be accessed by all the students in the Institute. You can not save changes to these files as they are protected. Any files you want to keep from the J drive can be copied to your personal file or 31/2 floppy (A:) drive. 72 Version 2 TPC Janine Ratcliffe 2010 Exercise 6 Copying and Editing a file 1. 2. 3. 4. 5. 6.

The internet is a huge collection of computers around the world. These computers are all linked together, and they can “talk” to each other, sharing information. If your computer is connected to the internet, it can connect to millions of other computers, in many different parts of the world. WHAT CAN YOU DO ON THE INTERNET? You can send electronic letters to people (e-mails) You can read pages on the World Wide Web (www) You can play games with people on the other side of the world You can chat to people You can even buy things on the internet and have them delivered to your home WHAT IS THE WORLD WIDE WEB? The World Wide Web (www) is part of the internet. It is a collection of millions of pages of information. This information can be about anything. HOW DO YOU MOVE AROUND THE WORLD WIDE WEB? The pages on the World Wide Web are all linked so that you can move around them. The pages are linked together using Hyperlinks. 87 Version 2 TPC Janine Ratcliffe 2010 Remember these three rules………. A hyperlink is usually coloured in blue and underlined If you move your mouse over a hyperlink, it will change to the shape of a hand, like this…. If you click on a hyperlink, you will go to a different page. WHAT IS THE ADDRESS BAR? One of the most important parts of your browser is the address bar. Every web page on the Internet has its own address. For example, the address of the Disney web-site is http://www.disney.com. INTERNET BROWSERS What is a browser? A browser is a computer program which allows you to view and interact with web pages. If you did not have a browser to view web pages, it would be a cumbersome and tedious task to access information on the Internet. Think of a browser as you would a word processing program, or any other type of program you are familiar with on your computer. If you want to carry out a task on a computer you need some kind of computer program. If you want to view web pages, you need a browser program. What are some of the most common browsers? There are a variety of companies that make browsers, many of which are free. The main browsers used today include: Netscape Navigator, Internet Explorer, Mozilla and Linux. Other less common browsers include: Opera, Galeon, Pheonix, Konqueror and Safari. How do I open my Internet browser? You will most likely find your Internet browser on your desktop. Look for the shortcut icon and then double-click to open your browser. Alternatively, you may need to click on the Start button and from the pop up menu choose Programs. From this list you should be able to find your Internet browser and click once on it to open it. You can then access a website by entering its web address or URL. Please note that it is important to read the privacy and other conditions of use for the websites you access. 88 Version 2 TPC Janine Ratcliffe 2010 What is a home page? Your browser’s home page is the screen you see first when you load/open your browser program. Usually this is the home page of your Internet service provider’s website, or the home page of your organisation’s intranet if you are accessing the Internet from a server in your workplace. You can change the home page for your browser. First you need to use your browser to go to the website page you wish to have as your browser home page. Then, in Internet Explorer (IE): Go to the Tools menu. Choose Internet Options. Choose General Tab. Click on Use Current. In Netscape, you also need to first use your browser to go to the website page you wish to have as your browser home page. Then: Click on Edit menu. Choose Preferences. Click on the Home page option. Click on Use Current Page. In other browsers, you can check the Help menu to find out how to do this. How do I adjust the display of my Internet browser? There are a number of features of your browser display which you can adjust. To change the fonts and colour in Internet Explorer (IE): Click on Tools menu. Choose Internet Options. Choose Colours and change text and background colours rather than windows colours, or change visited and unvisited sites colour, or hover colour as required. Choose Fonts and choose a font of your choice. (Remember this will only change fonts on web pages which do not have a specified text font.) 89 Version 2 TPC Janine Ratcliffe 2010 To change the fonts and colour in Netscape: Click on Edit menu. Choose Preferences. Choose Appearance. Change Fonts, Colours or Themes as required. (Remember this will only change fonts and colours on web pages which do not have a specified text font.) To adjust the available space on the screen to display information in IE: Choose View menu. Click on Full Screen option. To revert to showing menus, toolbars and status bar, use the shortcut F11 key. To remove toolbars in Netscape: Choose View menu. Remove the ticks (by clicking) on those toolbars you do not want to see. To revert to showing toolbars, choose View menu and replace the ticks beside the toolbars you wish to see. WEB ADDRESSES What is a uniform resource locator (URL)? A uniform resource location (URL) is a web address, or, the location of a specific website or web page. You need to have a URL entered in the address bar of your browser in order to go to that website. This acts as an instruction to go to a particular site on the Internet and display the information that is there. How are URLs structured? A URL is made up of three parts as follows: 1 the set of rules (protocol) used to transfer information from the remote computer (the one you are connecting to) to your computer 2 the name of the server (computer) where the information is held 3 the file name you need. So, the URL, or address, is made up like this: http://www.tafensw.edu.au/default 1 http:// — the protocol used to transfer information 2 www.tafensw.edu.au — the name of the server 3 default — the page you will first access at this website. More information is available from the URL when you look at it as five separate elements as follows: http://www.tafensw.edu.au/default 1 http:// — the transfer protocol 90 Version 2 TPC Janine Ratcliffe 2010 2 www — the type of server you are accessing (sometimes this element is not shown and you know you are accessing a server that is not available world wide, probably only available on an intranet to people inside your organisation) 3 tafensw — the name of the organisation 4 edu — the type of organisation (in this case educational) 5 au — the country where the server is located. Variations on this type of URL are: Transfer protocols might also include ftp:// or https://. The name of the organisation might be the full name, eg: microsoft or intel, or might be abbreviated, eg: hp for Hewlett-Packard or nla for National Library of Australia. The type of organisation might be com for commercial; gov for government; asn for association; org for organisation. The country where the service is located might be uk for the United Kingdom; fr for France or nz for New Zealand. Where no country is shown the server is located in the United States. Since the USA was the first country to use the Internet no country descriptor was initially needed. SUMMARY In this reading we’ve looked at the software that is used to access the Internet. This type of software is called a browser to allow you to browse information on the World Wide Web or on intranets. We’ve looked at the common browsers and how to adjust some aspects of the way the browser displays information. By now, you should be able to identify your own home page and the structure of a URL you might see on the World Wide Web. 91 Version 2 TPC Janine Ratcliffe 2010 SEARCH ENGINES A search engine is a tool we use to find websites and information on the Internet. Search engines will search other computers connected to the Internet and classify the files they find on these computers. Some search engines ‘crawl’ or ‘spider’ in different ways, while others create directories. Therefore, search engines need access to different computers connected to the Internet. For these reasons it is useful to use a variety of search engines. Common search engines At the time of writing, the most commonly used search engines include: Google Yahoo MSN Lycos AltaVista Netscape Ask. The URLs for each of these search engines are included in the Research section of this Learning Pack. Differences between search engines There are a huge variety of search engines. Most search engines explore most of the computers connected to the Internet. However, some ‘search engines’ are really a search of a particular site, or perhaps a group of sites. Some specialist search engines are based on specific topic areas. For example, Web Wombat was the original Australian search engine. When you use this search engine you will find your results listed in order of relevance to Australia. Other examples include: Lexplore — specialises in information related to international law Travelocity — specialises in information related to travel Hotwire — specialises in information related to computer and communications technology. HOW TO SEARCH THE INTERNET How to create a search expression In order to use a search engine, you must first locate the search engine on the Internet. Usually you would do this either by typing in the URL of the search engine you wish to use. A search bar will appear and you type your expression into this bar. How you express your search will be explained later. 92 Version 2 TPC Janine Ratcliffe 2010 Composing a search expression When you are looking for search terms try to: Type in the question in a full English sentence. Use just the main keywords. Add more keywords to narrow down (reduce) the number of hits. Define (by clicking a button) if you wish to search the entire web, or if you just wish to search Australian sites. Use synonyms for the keywords. Use acronyms. Use words to broaden your search like OR. Use words to narrow your search like AND, +, -, NOT. Use double quotation marks to ensure the phrase you are using is located in exactly that sequence. Also try different search engines. You will most likely get different results from the same search terms. How to narrow or broaden a search The trick to getting good results from your search expression is to be able to broaden or narrow your search as required. For some topics, you will get millions of results (or hits), while for others you might get none. As pointed out above you can: Use words to broaden your search like OR. Use words to narrow your search like AND, +, -, NOT. Instead of using Ninemsn, now let’s have a look at what we will achieve in Yahoo. Let’s search for information on the IT Certificate 2 qualification. Printing How to print search results The results of a search can be printed in two ways. The first way: 1 Choose File menu, then Print Preview. 2 If you are happy with what will be printed, click on the Print button. On clicking the print button you would create a hard copy of the two pages of this web page. Notice that you will also print the page title (the name at the top of each page), and the URL of the page at the bottom of the page. The second way: 1 Select the text and graphics you want to print. 2 Choose File menu, then Print. 93 Version 2 TPC 3 Janine Ratcliffe 2010 At the next screen, go to Page Range, click in the circle next to the word Selection. BOOKMARKS AND FAVOURITES The terms bookmark and favourite refer to the same function of a browser. In Netscape, the term used is Bookmark, while in Internet Explorer the term used is Favourite. You can use bookmarks to store the locations of websites you use often or find of particular value. Of course, this saves having to remember the URL of the particular website you have visited and saves lots of time when accessing the Internet. You can also organise your bookmarks, or favourites, into folders so that information on any particular topic can be grouped together. This is a really useful way to avoid having to search many times for something you’ve visited in the past. How to place a bookmark or favourite In Internet Explorer: 1 Go to the website you wish to save as a favourite. 2 Choose Favourites menu or click on the Favourites button on the toolbar. 3 Choose Add To Favourites. 4 At the next screen, click on Create In if you cannot see the New Folder option. 5 Now click on New Folder if you wish to create a new folder. 6 Name your folder and click on OK. 7 Ensure the folder you want to save into is open. 8 Change the name of the page against Name if you feel it is not a very helpful name. 9 Click on OK.

Then click on the name of the site you have recorded from this list. 3 Your browser will display the website requested. SUMMARY In this reading we’ve looked at a variety of search engines and search expressions. We have discovered that search engines vary slightly in the way they carry out searches, and therefore in the search results you will get. We’ve also discovered that there are a number of ways to broaden and narrow a search to get useful information from the Internet. Having successfully retrieved the information from the Internet, we have looked at three different ways to save this information electronically or in hard copy form. A quick way of retrieving information you have previously found on the Internet is to record ‘favourites’ or ‘bookmarks’, then return to them by choosing them from your personalised list. 96 Version 2 TPC Janine Ratcliffe 2010 How to return to a bookmark or favourite In Internet Explorer: 1 Choose Favourites menu or click on Favourites button on the toolbar. 2 Click on the name of the website you have saved, or if necessary double-click to open the folder holding the name of the website.

Searching through this information can sometimes be like searching for a needle in a haystack – absolutely impossible. It is very easy to find lots of web-sites which don’t contain the information that you need, and it sometimes seems that you are never going to find what you want to know. However, don’t get stressed if you can’t find something HOW DO YOU USE THE FIND TOOL? If you discover a very long web page which has lots of information, you can use a great browser tool to search through the page for things that might be useful to you. This is called the “Find” tool and it helps you…. FIND things! To load the Find tool, you can either… a) Choose find from the EDIT menu: b) Or press Ctrl and F at the same time. The FIND tool quickly searches through a web page looking for words you tell it to find. (It may look a little different on your computer) HOW CAN YOU COPY THINGS YOU HAVE FOUND? Computers let you copy text and pictures from web sites so that you can use them in your own work. Copying Text Your computer has lots of memory which it uses to remember things.

E-mail is the abbreviation for electronic mail, a method of transferring messages using the Internet. An E-mail message is also referred to as an e-mail. 99 Version 2 TPC Janine Ratcliffe 2010 Advantages. First of all, it is simple. Secondly, it is fast. With a lot of people having computers and Internet access at home and at the office, e-mail has become one of the commonly used methods of communication. E-mail allows you to send messages to people around the world. Many people are getting E-mail addresses because it is such a cheap and fast way to communicate. Here are some examples of Internet E-mail addresses: joel@solutions-4u.com president@whitehouse.gov someone@unbc.edu jmm@grfn.org someone@freenet.vancouver.bc.ca E-mail addresses usually consist of a name or initials followed by the at symbol (@) and then the name of the service the person has their Internet account on. The last portion of the address (e.g. com, gov, edu) tells you what kind of service the E-mail address belongs to. Com stands for commercial. Gov stands for government. Edu stands for education. Org stands for a non-profit organisation. Notice that all of the letters in the E-mail address are in lower case. This is usually done for simplicity however the computer does not care. HOW DO I GET AN E-MAIL ACCOUNT SO I CAN SEND AND RECEIVE E-MAILS? 100 Version 2 TPC Janine Ratcliffe 2010 There are thousands of services available on the Internet that will allow you free access to an e-mail account. For this activity we will use Yahoo. Just in case you don't have an account yet, this next section will help you establish one. Type www.yahoo.com in the address bar and click enter. Then click on “Free Mail: Sign Up”. Then click on “Sign Up for Yahoo Mail” Where it says preferred content, click on the arrow and find Yahoo Australia. Fill out the rest of the form. HOW DO I SEND AND RECEIVE E-MAILS? 101 Version 2 TPC Janine Ratcliffe 2010 Once you have an e-mail account you can send and receive e-mails. To send an e-mail you need to: Type www.yahoomail.com.au into the address bar. (you could put this address on your Favourites) Then you have to type in your e-mail address and password. Once you have done that your e-mail account will open. Click on compose to send an e-mail Type in the address you want to send the e-mail to You have to give a little bit of information about the message in the ‘Subject’ box. Type your message in the box below. You can use your toolbar to change size, shape, and colour and add pictures. Once you have finished click on send. 102 Version 2 TPC Janine Ratcliffe 2010 E-mail Etiquette Key rules for e-mails… Provide a meaningful subject line: “Hi” doesn’t help anyone see the value in reading your e-mail message. Instead it should be a summary of the message’s contents. Do not use all capitals. Use a mixture of upper and lowercase letters, just as you normally would. USING ALL CAPITALS MEANS THAT YOU ARE SHOUTING OR ANGRY. Do not forward your e-mail messages to anyone, especially a public discussion group, without the permission of the sender. Informality is okay. We all learned the rules of formal conversation in school, but e-mail more closely resembles conversation. This is not to say that you can relax all the rules. Remember not to say anything regarding business or legal issues that you would not place in writing as the e-mail can be simply printed off and shown to other people. Learn e-mail acronyms and smileys to convey your message. E-mail like other recent technologies have their own language. There are a number of acronyms that you can use, for example, to show you are attempting humour in your e-mail messages you can use :- for a smiley and g means to grin. How you sign off your e-mail will depend on whom you are writing to and the subject you are addressing in your e-mail. Many people use regards or cheers as they feel appropriate. E-mails are able to carry viruses. E-mails have been used to spread viruses across the world. Always scan attachments, particularly if you are unsure of the identity of the sender. Business e-mails should be only used for business. Remember your e-mails can be printed off and shown to others. Your business e-mail is not intended to be used as a means of sending jokes around the office. 103 Version 2 TPC Janine Ratcliffe 2010 The Internet Course Materials Access the Internet Activities Introduction to the Internet multimedia demonstration Useful Websites Information Skills Internet searching to support learning and teaching Internet Detective - online tutorial designed to help students develop the critical thinking required for their Internet research.

Specifically, the learner should be able to: · create simple spreadsheets · produce spreadsheets · produce a simple chart. A spreadsheet is a type of computer program that contains and can add, subtract multiply and divide text or formulas in rows and columns. They are commonly used for budgets. Forecasting and other finance related tasks. In a spreadsheet program data and formulas are entered into a ledger like form (spreadsheet or worksheet) for analysis, tracking, planning or what-if evaluation of the impacts of real or proposed changes on a strategy. Spreadsheet programs use rows and column of cells. Lets look at a standard page of Microsoft Excel When you first open Microsoft spreadsheet (we will call it Excel) you will use most of the features we have labelled for you. We can add in three types of entries. Text Numbers Formulas (formulas do our sums for us) Exercise 1 1. Open Microsoft Excel 2. Click with your mouse on A1 to make it an active cell (this means you can type your text, data or formula in this cell as it is now opened) 3. Type MBI Computer Corporation 115 Version 2 TPC Janine Ratcliffe Type out the following to complete your table. TIP: To move from cell to cell use your TAB key on your keyboard to move you across the cells on your page. You can also use the arrows keys on your keyboard or the mouse. Just click in each cell. 116 Version 2 2010 TPC Janine Ratcliffe 2010 Type the following information in the Age and Salary cells (Column C and D) 117 Version 2 TPC Janine Ratcliffe 2010 Now we are going to name our sheet To do this right click on the sheet tab at the bottom of the excel sheet. Then click on rename when the menu appears and type in Salary. Now save your document to your folder contained in My documents and reopen once saved. We are now going to create a formula to add up the combined age of the people contained in the spreadsheet and add up the total wage (or salary) of the people. 118 Version 2 TPC Janine Ratcliffe 2010 Exercise 2 Click and drag your mouse from Column C row 4 and drag your mouse all the way down to Column C row 14 (this should look a light blue). Release your mouse and go to the top menu bar and select the AutoSum button (below) You should have the answer 317 once you have pressed the AutoSum button. Next select cells D4 to D13 by highlighting with your mouse. Click the AutoSum button again to give you the total wages of the employees. 119 Version 2 TPC Janine Ratcliffe 2010 Now we are going to make the excel sheet easier to read by formatting our text. This is very similar to Microsoft Word. Exercise 3 1. 2. 3. 4. 5. 6. 7. 8. Click on cell A1 (the very first cell). Select Bold on your toolbar Change font to Arial and size 10 Click the centre button on the toolbar Select all the employees Last names and make them Bold, Arial and 14 Click on the Totals (eg 317 and 3350000) and make them bold as well. Click on row number 3 to select the whole row. Make this row Bold, Arial and 14 point Sometimes we cannot see all of the text that is entered on the spreadsheet so we need to make the column wider or the row longer. To do this We need to place the mouse button on the toolbar and double click between the column you want wider or with the mouse drag the column or row to where it is wide enough to see the text or number 120 Version 2 TPC Janine Ratcliffe We can also place our text anywhere in the cell by selecting left, centre or right like we do for word processing. Exercise 4. Highlight column C and place the text in the centre by selecting the centre button on the toolbar. 121 Version 2 2010 TPC Janine Ratcliffe Next place a border around the totals columns. To do this select the cells C13 and the borders tab on the toolbar. Repeat the same step for cells D13. Print out this sheet, place in your portfolio and save to your file. 122 Version 2 2010 TPC Janine Ratcliffe 2010 Exercise 5 Type the following in a new worksheet. When you have several words or text in a cell you can join the cells together so all of your text is on screen and can print out all at once. This process is called to Merge a Cell. To do this we need to open a menu. 123 Version 2 TPC Janine Ratcliffe 2010 Exercise 6. Select row 1, columns A,B,C and D Right click your mouse on the highlighted cells to bring up a menu. Go to Format Cells on the menu and lift click with your mouse Click on the Alignment tab on the menu the click to place a tick in the merge cells box. 124 Version 2 TPC 125 Janine Ratcliffe Version 2 2010 TPC Janine Ratcliffe 2010 Also select the Horizontal and Vertical drop down arrows which will place all of your text that in highlight in that cell in the centre vertically and horizontally. We can also use this menu to wrap our text in one cell (This will split your text into several lines if you wish). Next we will add up our excel sheet sums. Before we used the add function. This time we are going to find the totals and the average. We do this by using a formula. In formulas we use the formula toolbar. If you look back at when we used the AutoSum button and click on one of the totals results you will notice in the formula toolbar there is the row number and columns you selected to add up. The AutoSum has created a formula for you. In this exercise we will create the formula. Click in cell D5. Click in the formula bar and type the following =AVERAGE (B5/C5) This formula tell us we want an answer (=) the AVERAGE (Difference between the highest and lowest) and the Cells we want the average. Once you have type in the formula press enter and your answer will appear in the D Column. 126 Version 2 TPC Janine Ratcliffe 2010 Once you have created a formula and you need some more answers but don’t want to keep typing the formula you can excel to do the hard work for you. If you gently place your mouse at the small black square at the bottom corner of the D cell you will see your mouse change to a small +. Click and drag down to row 8 and release your mouse. This will automatically place the same formula in each of the cells for you. 127 Version 2 TPC Janine Ratcliffe 2010 Next we are going to change the way column B looks buy putting a dollar sign ( $ ) into the cells. Select Column B. 1. 2. 3. 4. 5. Right click on the column Select Format cells from the menu Select the Number tab Select Currency Click OK You can use this menu to make your pages suit you. 128 Version 2 TPC 129 Janine Ratcliffe Version 2 2010 TPC Janine Ratcliffe 2010 How to create a chart. To select the Figures or data your would like included in your chart highlight from cells B5 to D8 with your mouse. Se 130 Version 2 TPC Janine Ratcliffe 2010 From the menu bar select chart tab or Insert, Chart. This will create a wizard which will do all the hard work for you. Follow the wizard through till finish and select the finish tab. Your chart should look like this. Other hints with Excel INSERT BLANK CELLS, ROWS, OR COLUMNS 1. Do one of the following: Insert new blank cells Select a range of cells where you want to insert the new blank cells. Select the same number of cells as you want to insert. Insert a single row Click a cell in the row immediately below where you want the new row. For example, to insert a new row above row 5, click a cell in row 5. 131 Version 2 TPC Janine Ratcliffe 2010 Insert multiple rows Select rows immediately below where you want the new rows. Select the same number of rows as you want to insert. Insert a single column Click a cell in the column immediately to the right of where you want to insert the new column. For example, to insert a new column to the left of column B, click a cell in column B. Insert multiple columns Select columns immediately to the right of where you want to insert the new columns. Select the same number of columns as you want to insert. 2. On the Insert menu, click Cells, Rows, or Columns. 3. If you are moving or copying a range of cells, and not a row or column, in the Insert Paste dialog box, click the direction to shift the surrounding cells. Remember. Use formatting as you would in Microsoft Word. This includes: - fonts, font sizes, borders, patterns/colours, bold, italics, currency, alignment, wrap text, decimal places. Always check the print preview before printing out and adjust your spreadsheet if you need to by altering the columns or rows etc. When printing out, select the sheet you wish to print out then print the sheet. We are now going to create a budget for your living expenses. Copy the attached sheets and format the way it is printed out.

A basic computer system could be described as being made up of four principle parts: 1 Input 2 Process 3 Output 4 Storage. 176 Version 2 TPC Janine Ratcliffe 2010 Input describes the hardware and actions required to get data physically into a computer system. The most obvious pieces of hardware for this task are the keyboard and mouse. Process describes the internal computer hardware that actually carries out the tasks required by the user in order to achieve a goal. For example, the Central Processing Unit (CPU) is often referred to as ‘the brain’. It can take two numbers and add them together in order to produce a result. While this sounds as though the computer is an overrated calculator, there is much more going on inside. Output describes the hardware needed to present the information. The most obvious piece of hardware is the monitor. Other terms used are screen and display unit. Storage describes the hardware required to remember (store) both the data and the programs used to perform some action on the data. There are two main types of storage: temporary (also called volatile) which is lost when the computer is turned off, and permanent (non-volatile) which is used to permanently store both the data and programs that use that data. GETTING INFORMATION INTO A COMPUTER (INPUT DEVICES) If we look at only those pieces of hardware that are used to get information into a computer system, we can come up with a simple list like: keyboard mouse touch-screen scanner bar-code reader microphone digital camera. In this reading we will only be examining the basic keyboard and mouse. Keyboard If you look at the range of keyboards on the market (see vendor websites, computer stores or trade fairs) you will see a variety of shapes, sizes and colours of keyboards. But they all perform the same basic task. That is, you press a key and the number that represents that key is sent to the system unit. Note, that it 177 Version 2 TPC Janine Ratcliffe 2010 is a number not letter because, internally, computers do not understand letters, only numbers. So each letter on the keyboard is assigned a number. The most common keyboard in use today is the QWERTY keyboard. It gets it name from the first row of keys as seen in the picture below. Along with the letters of the alphabet, there are number keys, arrow keys, function keys (F1-F12) and special keys that work differently with depending on the key combinations used. For example you can often press the Escape (Esc) key to cancel an un-intended operation, or to clear the screen of a message. Or there is the Open Apple key on a Mac for special functions. Take another look at the image above and notice that the connector for the keyboard is a small round plug called a PS2 connector. It is possible to get other types of connectors such as USB (Universal Serial Bus), Infra-red and Wireless, Firewire. We won’t be examining these in detail. Mouse The other most often used input device is the mouse. Once again they can some in all sorts of colours and various types of connectors. Most mice on a personal computer (PC) have two buttons, while the typical mouse on an Apple Mac has only one button. The mouse operated simply on a small weighted ball that can move two rollers. One roller determines how much vertical movement, while the other determines the horizontal movement. 178 Version 2 TPC Janine Ratcliffe 2010 One extra feature on the mouse today, that is not traditional, is the scroll wheel. It can be used to scroll up and down a document. It can even operate as a third button. The most common connector is a PS2, the same as the keyboard. This means it is possible to connect both the keyboard and mouse in the wrong sockets. This will not harm the computer but it will not function correctly. As with the keyboard, it is possible to get other types of connectors such as USB (Universal Serial Bus), Infra-red and Wireless. We won’t be examining these in detail. GETTING INFORMATION OUT OF A COMPUTER (OUTPUT DEVICES) Getting information out of a computer and presenting to the user in some useable form can be performed by a number of hardware devices. These devices could include: screen (also called a monitor or display) printer speakers. Let’s take a look at the screen and printer. Screen The primary output device is the screen. The computer screen has changed noticeably from the original plain text monochrome (single colour, eg white, amber or green text on a black background) to the new thin flat panel highresolution models. When selecting a screen the main factors to be considered are: 1 Its physical size — measured from diagonally opposite corners, eg 15'' or the bigger 19-21'' (note the Imperial measurement — inches) 2 Technology — cathode ray tube (CRT) or liquid crystal display (LCD) 3 Resolution — a measurement of the number of dots (called pixels) that it is capable of displaying. LCD and CRT monitors The most common type of monitor on the market today is the 15-17'' CRT display. It uses a combination of three colours (red, green and blue) to produce the high quality colour images. The resolution is the measure of dots (called pixels) on the screen. The measurement is taken horizontally and vertically, eg 800 pixels across by 600 pixels down is referred to as 800 × 600. The monitor connects to a special 15pin connector located on a display adapter. It is the display adapter that determines the colour depth that a screen can produce. In theory the screen is not limited in the colour depth available. The 179 Version 2 TPC Janine Ratcliffe display adapter has a limited amount of memory. It is this memory that determines the colour depth that can be displayed. 2010 Printers When the output from a computer is required to be a more permanent form than displaying it on a screen, a printer is required. There are three basic types of printers, classified by their method of producing a printed page: 1 laser 2 inkjet 3 dot matrix. Regardless of the technology used to put the printed word or image on the page, the quality of the output is referred to as its resolution. Print resolution is measure in dots-per-inch (dpi) and, generally, the higher the dpi the better the quality. Every computer is fitted with a special connector (called a port) that is designed to work with printers. The connection is called a printer port and is easily recognised as the only 25-pin female socket. However, most printers today use a USB connector. The USB connector allows devices to be disconnected and connected while the computer is operational (hot swapping). Laser Laser printers are known as non-impact printers and they are much quieter than dot-matrix printers. They are also generally faster than other types of printers. 180 Version 2 TPC Janine Ratcliffe 2010 A standard monochrome laser printer employs a single toner, whereas colour laser printers use four toners to print in full colour. Colour laser printers are generally about five to ten times more expensive than the monochrome type. As the information on the whole page needs to be stored in the printer before it can produce the page, the amount of memory in the printer can affect its highresolution potential. This is especially true when dealing with high-resolution graphics. Laser printers use a laser beam to create an image on a drum. The light of the laser changes the electrical charge in the drum wherever it gets hit. Then, the drum is rolled onto a reservoir of toner (black powder), which is picked up by the drum. Consequently, the toner is being transferred to the paper by heat and pressure, in the same way a photocopier operates. Since an entire page is carried over to a drum prior to the toner application, laser printers can be called page printers. One of the distinguishing features of laser printers is their resolution. Their resolutions range from 300 dpi (dots per inch) at the bottom end to 1,200 dpi at the top end. In the commercial offset printing world, they normally print at 1,200 or 2,400 dpi. Some laser printers achieve higher resolutions with distinguishing techniques generally known as resolution enhancement. Inkjet An inkjet printer is any printer that places extremely small droplets of ink onto paper to create an image. If you ever look at a piece of paper that has come out of an inkjet printer, you know that: The dots are extremely small (usually between 50 and 60 microns in diameter), so small that they are tinier than the diameter of a human hair (70 microns)! The dots are positioned very precisely, with resolutions of up to 1440 × 720 dots per inch (dpi). The dots can have different colors combined together to create photoquality images. 181 Version 2 TPC Janine Ratcliffe 2010 Inkjet printing has two chief benefits over laser printers: lower printer cost and color-printing capabilities. But while inkjet printers are priced much less than laser printers, they are actually more expensive to use and maintain. Cartridges need to be changed more frequently and the special coated paper required to produce high-quality output is very expensive. At a cost per page level, inkjet printing costs about 10 times more than laser printing. Inkjet printing, like laser printing, is a non-impact process. Ink is emitted from nozzles while they pass over the page. The operation of an inkjet printer is easy to visualise: liquid ink in various colors being squirted onto paper and other media, like plastic film and canvas, to build an image. A print head scans the page in horizontal strips, using the printer’s motor assembly to move it from left to right and back again, while the paper is rolled up in vertical steps, again by the printer. A strip (or row) of the image is printed, then the paper moves on, ready for the next strip. To speed things up, the print head doesn’t print just a single row of pixels in each pass, but a vertical row of pixels at a time. The coloured output is produced by mixing the colours cyan, magenta, yellow, and black, often referred to as CMYK. The colours are often contained in two cartridges: 1 a three-colour cartridge containing cyan, magenta and yellow 2 one higher-capacity black cartridge. Print speeds are now available for inkjets that are close to those of current colour laser printers: three to four pages per minute (ppm) in color, and 12 to 14 ppm in monochrome. Dot matrix Dot matrix printers are the oldest of the three technologies used in most of today’s printers. They are still common in cases when a user needs to print multipart or pin-fed forms. They are noisy but very cheap to operate. 182 Version 2 TPC Janine Ratcliffe 2010 As paper is fed through the printer, it runs across a flat piece of metal called a platen. A print-head fires an array of pins into an inked ribbon that strikes the paper as it crosses the platen. The array of pins is fired at precise times to form characters or pictures on the paper. A dot-matrix printer can use tractor-fed paper or friction rollers to feed paper into the printer. Tractor feeds either push paper into the printer or pull paper out of the printer to move paper. In a printer using friction rollers, the feed mechanism usually pushes the paper into the printer. PORTS FOR CONNECTING INPUT AND OUTPUT DEVICES Serial port A type of interface in which only one (1) bit of data is transferred at a time. Mice and modems are usually connected to serial ports, which are also referred to as COM ports. Parallel port A type of interface that allows more than one (1) bit of data to be processed at once. Printers are the most common peripheral devices connected to parallel ports. 183 Version 2 TPC Janine Ratcliffe PS/2 2010 Another type of port (or interface) that can be used to connect mice and keyboards to the computer. The PS/2 port is sometimes called the mouse port. Universal serial bus (USB) connection to a computer that supports up to 127 devices per USB interface. USB transfers data at speeds of 12 Mbps (megabits per second). This technology is being widely used and may USB, a connection standard for quick and easy device supersede the original serial interface. Firewire A very fast external bus that supports data transfer rates of up to 400 Mbps developed by Apple, FireWire falls under the IEEE 1394 standard. Used to connect digital cameras and memory cards. HOW WORK GETS DONE (PROCESSING) The piece of computer hardware that forms the main workhorse or brain is the Central Processing Unit (CPU). Any work that needs to be done is performed by this small component. When someone asks you ‘What sort of computer is this?’ the question often translates to ‘What CPU does this computer have?’. It is primarily the CPU that determines the speed and processing capabilities of the computer. In the Apple Mac world, the CPU is manufactured by Motorola with the latest model being the G5. In the PC (personal computer) world, the CPU is manufactured primarily by Intel, AMD, Cyrix and others. The latest and most popular personal computer CPU models being the Intel Pentium IV and the AMD Athlon. 184 Version 2 TPC Janine Ratcliffe 2010 The CPU will likely be the larger of the chips on the motherboard inside your PC. The motherboard is the large circuit board inside the system unit. The CPU will be covered by a heat-sink and fan. The heat-sink and fan are extremely important. Without these the CPU would get too hot to work and possibly melt or burn out. 185 Version 2 TPC Janine Ratcliffe 2010 The actions that the CPU performs are quite simple. There are four things that the CPU will repeatedly do: 1 fetch a piece of program code 2 decode that into a set of useful instructions for the computer 3 execute those instructions, eg add two numbers together 4 store the result somewhere. Those four steps above are called a processing cycle. One cycle performed in one second is measured as 1 Hz (Hertz). To keep the timing for all these actions synchronised, a clock chip is added (much like the crystal that keeps a digital watch running on time). The measurement of the clock in relation to the CPU’s speed is measured in MHz (megahertz) or more recently GHz (gigahertz). A chip with a megahertz rating of 900MHz would be able to complete 900 million cycles every second. However, this speed rating only shows how many clock cycles the CPU can do in a second. How much being done in each cycle is another matter. REMEMBERING THE INFORMATION (STORAGE) If computers were not able to store information then they would be little more than glorified calculators. There are two main type of storage: 1 primary (volatile) 2 secondary (non-volatile). The amount of storage that a computer has affects it ability to operate efficiently, its performance and capabilities. Primary storage Primary storage in a computer is volatile. The term volatile, in this context, means that if you switched off the computer, then all the contents stored in that form of memory would be lost. So, volatile memory is a form of storage that is only temporary. When any program is run on a computer, it is run in memory called random access memory (RAM). While RAM is volatile, it is also very fast. As computers run at speeds in the millionth or billionth of a second, fast memory is critical to its operation. RAM operates in nanoseconds (ns) ie billionths of a second. Memory module (RAM) The word random in random access memory is not meant to infer that things happen in an ad hoc fashion, but that any location can be accessed at random. Think of the construction of RAM like that of a post office. If you look at the post 186 Version 2 TPC Janine Ratcliffe 2010 office boxes you will see a matrix of storage holes, each numbered, and able to have letters added and removed at random. Each box corresponds to a location or address. The face of RAM has changed dramatically since the early days of computing. We had the SIMM (SIMM was a Single Inline Memory Module). Then came the DIMM (Double Inline Memory Module). The introduction of DIMMs brought with it new speeds and sizes to give computers more power than ever before. The other advancement in recent years has been the introduction of DDR RAM (Double Data Rate). DDR effectively doubled the speed that RAM could transfer data without actually increasing the MHz. For example, a stick of PC133 (133MHz) RAM with DDR would effectively transmit data at 266MHz but still have an underlying speed of 133MHz. Secondary storage As the contents of primary storage (RAM) are lost when the computer is switched off, there is an obvious need for a more permanent solution. The main form of secondary storage is the hard disk drive. Secondary storage is non-volatile, which means the contents are permanent. It is possible for your computer to function without a hard disk, however it would be basically useless to you as you would not be able to use an operating system or have any programs to use. Hard disks use circular hard platters to store data on. They are in pristine condition with a mirror like finish to them. These platters are locked away inside a steel casing as unclean air can easily ruin a hard disk. This is why you should never remove the casing from the hard disk, as it is very unlikely you will be able to put it back together as a working component Above you can see a labelled diagram of a hard disk. The model is a SCSI (Small Computer Scientific Interface). You can see the hard platters on top of each other with a set of arms that hold the read/write head. The speed of the arm is truly amazing as well as the accuracy of the head, which can read and write to perfection on a platter that is rotating around 7200Rpm. On each of the platters there is a thin layer of magnetic film. Data storage on hard disks is very similar to that of a cassette tape. Data is stored in many 1’s Version 2 187 TPC Janine Ratcliffe 2010 and 0’s. These binary digits are arranged in different ways to represent different characters. When these are read back by the head the data is retrieved and processed. There are currently three connections for an internal hard disk: 1 IDE (or ATA) 2 SCSI 3 Serial ATA. It is also possible to connect a hard disk externally (like connecting a printer) using USB or Firewire. However, the most common is the IDE interface. This provides a 40-pin connection to most standard motherboards and you can’t normally go wrong buying an IDE drive for your machine. SCSI connections (50pin) often require extra hardware unless it’s built into your motherboard. SCSI hard disks are often faster but more expensive than their IDE counterparts. The newest type is Serial ATA. The Serial ATA standard is more reliable and uses smaller, unobtrusive wires. INTERACTING WITH THE USER (OPERATING SYSTEMS) All computers have an operating system. Any desktop or laptop PC that you buy normally comes pre-loaded with a version of Microsoft Windows. Macintosh computers come pre-loaded with another operating system. Many corporate servers use the Linux or UNIX operating systems. The operating system (OS) is the first thing loaded onto the computer. Without an operating system, a computer is useless. More recently, operating systems have started to pop up in smaller computers as well. Operating systems can now be found on many of the devices we use every day, from mobile phones to wireless access points. The computer in a typical modern mobile phone is now more powerful than a desktop computer from 20 years ago The purpose of an operating system is to organise and control hardware and software so that the computer (or device) behaves in a flexible but predictable way. Not all computers have operating systems. For example, the computer that controls the microwave oven doesn’t need an operating system. It has one set of tasks to perform, very simple input to expect (a numbered keypad and a few preset buttons) and simple, never-changing hardware to control. For a computer like this, an operating system would be unnecessary because it runs a single hardwired program all the time. An operating system creates the ability to: serve a variety of purposes interact with users in more complicated ways keep up with needs that change over time. All desktop computers have operating systems. The most common are the Windows family of operating systems developed by Microsoft, the Macintosh operating systems developed by Apple and the UNIX family of operating systems (which have been developed by a whole history of individuals, corporations and collaborators). There are hundreds of other operating systems available for special-purpose applications, including specializations for mainframes, robotics, and manufacturing, real-time control systems and so on. At the simplest level, an operating system does two things: 188 Version 2 TPC Janine Ratcliffe 2010 1 It manages the hardware and software resources of the system. In a desktop computer, these resources include such things as the processor, memory and disk space. 2 It provides a stable, consistent way for applications to deal with the hardware without having to know all the details of the hardware. The first task, managing the hardware and software resources, is very important, as various programs and input methods compete for the attention of the central processing unit (CPU) and demand memory, storage and input/output (I/O) for their own purposes. In this capacity, the operating system plays the role of the good parent, making sure that each application gets the necessary resources while playing nicely with all the other applications. It is also busy controlling the limited capacity of the system to the greatest good of all the users and applications. The second task, providing a consistent application interface, is especially important if there is to be more than one of a particular type of computer using the operating system, or if the hardware making up the computer is ever open to change. A consistent application program interface (API) allows a software developer to write an application on one computer and have a high level of confidence that it will run on another computer of the same type, even if the amount of memory or the quantity of storage is different on the two machines. Even if a particular computer is unique, an operating system can ensure that applications continue to run when hardware upgrades and updates occur. This is because the operating system, not the application, is responsible for managing the hardware and the distribution of its resources. One of the challenges facing developers is keeping their operating systems flexible enough to run hardware from the thousands of vendors manufacturing computer equipment. Today’s systems can accommodate thousands of different printers, disk drives and special peripherals in any possible combination. Windows XP interface 189 Version 2 TPC Janine Ratcliffe 2010 Linux interface Types of operating systems Within the broad family of operating systems, there are generally four types, categorised based on the types of computers they control and the sort of applications they support. The broad categories are: Real-time operating system (RTOS) — Real-time operating systems are used to control machinery, scientific instruments and industrial systems. An RTOS typically has very little user-interface capability, and no end-user utilities, since the system will be a ‘sealed box’ when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time every time it occurs. In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy. Single-user, single task — As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system. Single-user, multi-tasking — This is the type of operating system most people use on their desktop and laptop computers today. Microsoft’s Windows and Apple’s MacOS platforms are both examples of operating systems that will let a single user have several programs in operation at the same time. For example, it’s entirely possible for a Windows user to be writing a note in a word processor while downloading a file from the Internet while printing the text of an email message. Multi-user — A multi-user operating system allows many different users to take advantage of the computer’s resources simultaneously. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn’t affect the entire community of users. Unix, 190 Version 2 TPC Janine Ratcliffe VMS (see ‘Terms’) and mainframe operating systems, such as MVS (see ‘Terms’), are examples of multi-user operating systems. 2010 Starting up (booting) When the computer is first switched on, and before it can do any useful work, it performs a power on self test (POST). You will see information appear on the screen that relates to the type and amount of hardware components, such as RAM, hard disk capacity, etc. Once the self-test is complete, the computer loads the operating system. Once the operating system is loaded the computer can now run other programs called applications. RUNNING PROGRAMS (APPLICATIONS) Once the operating system is loaded, it is now possible to run other programs. Usually these programs are designed to perform some useful task or application. So distinguish the programs that you would use, from the necessary collection of programs (utilities) that make up the operating system, the term application is used. When the application requires the use of a piece of hardware, such as a printer, it must do so in an orderly fashion. For example, if you were using a word processing application, and you selected the Print option, the following generic events would occur: 1 The word processor sends to the operating system the information it wants to print through an application program interface (API). 2 The operating system then delivers the information to a special program that controls the printer, called a device driver (this would be referred to as a printer driver). 3 The printer driver then forwards the information and controls the communication with the printer at the hardware level. So under the surface there is much interaction between different programs performing different tasks. It is not surprising then that the typical computer system experiences problems. Another way of looking at it is that, the modern computer operates extremely well considering the complexities involved. SUMMARY The basic computer hardware comprises components that have the roles of: 1 Input 2 Process 3 Output 4 Storage. Each hardware device serves a specialty role and differs in the connections used. Some hardware devices are internal to the system unit, such as the video card, while others are external and called peripherals. Some devices can have more than a one type of connector. For example a mouse could connect using a PS2 or USB port. Other peripherals, such as printers, can be connected to expand the capabilities of the system. Each peripheral has its own technology and ways of achieving its task. For example, laser printers use an entirely different technology to print a page than does an inkjet printer. Hardware devices require special programs, called device drivers, to function correctly. 191 Version 2 TPC Janine Ratcliffe 2010 The central processing unit (CPU) is the brain of the system, but is dependant on other parts such as RAM and hard disk drives to be able to perform any useful task. The computer is often rated by its speed, which is measure in megahertz (MHz) or gigahertz (GHz). No personal computer can function without an operating system. The operating system acts as the go-between of applications and the hardware. Operating systems are complex programs but provide the ability for a computer to perform many different tasks.

The law describes the responsibilities of the various parties such as employers, workers, and people who supply equipment or chemicals to workplaces. In NSW these requirements are mostly in the relevant legislation, that is, the Occupational Health and Safety Act 2000 and the Occupational Health and Safety Regulation 2001. Further requirements are set out in various codes of practice and standards referred to in the legislation. Employers’ duties The law requires employers to ensure the health, safety and welfare at work of all their employees and other people at the workplace, including clients and visitors. This is referred to as the employer’s duty of care. To fulfil this duty, employers must ensure that the premises, machinery and equipment, chemicals, systems of work and the working environment are safe and without risks to health. Employers also have to provide such information, instruction, training and supervision as may be necessary to ensure the employees’ health and safety. Employers in New South Wales must use hazard identification and risk control processes to fulfil these legal obligations. 193 Version 2 TPC Janine Ratcliffe Employees’ duties 2010 Employees also have duties under the legislation. They must take care not to endanger their own or others’ health and safety. They must comply with the employers’ systems for ensuring health and safety, and they should take part in the hazard identification and risk control process. More information about OHS legal requirements can be found on the WorkCover NSW website at http://www.workcover.nsw.gov.au As a worker, you are entitled to expect safe and healthy working conditions, but you need to participate in arrangements made for health and safety in order to help create and maintain those good health and safety conditions. Success in managing health and safety risks depends on the participation and cooperation of all workers. By reporting OHS hazards and following procedures that have been established to protect health and safety, you can contribute to a workplace which is safer for everyone. While the main responsibility for making sure that work activities are safe lies with the employer/owner of a company, there is a general expectation that employees work safely and take care in what they do so as not to put themselves or others at risk. You can be expected to: follow procedures wear personal protective equipment (PPE) report any safety problems report incidents and injuries. While you do have a role to play in creating a safe workplace and in keeping it that way, you will only be able to meet these responsibilities if procedures such as PPE and reporting systems are in place. Workstation set up and OHS legislation There is very little Australian legislation for the set up of workstations. Following is a list (of Australian and overseas information sources) where you can find related information: Australian Standard AS 3590.2-1990, Screen-based workstations; Part 2:Workstation furniture British Standard BS 5940: Part 1:1980, Office furniture, Part 1. Specification for design and dimensions of office workstations, desks, tables and chairs Health and Safety Executive (1991) Seating at Work, London: HMSO German Standard DIN 4551, 1975, Office furniture: Revolving office chair with adjustable back, with or without armrests, adjustable in height Ergonomic guidelines for use by the Australian Public Service, prepared by the RSI Task Force Implementation The Ergonomic Unit of WorkSafe Australia offers advice in their publication Ergonomic Principles and Checklists for the Selection of Office Furniture and Equipment National Occupational Health Commission at: www.nohsc.gov.au has issued fact sheets entitled Workplace Layout and Design, Comfort at Work, Plant and Equipment Hazards, and Overuse Injuries 194 Version 2 TPC Janine Ratcliffe 2010 The National Standard for Manual Handling and the National Code of Practice for Manual Handling give information regarding lifting and bending. These are standards that must be following when lifting and placing computer equipment during the set up stage. OCCUPATIONAL OVERUSE SYNDROME (OOS) OOS, also known as repetition strain injury (RSI), is a collective term for a range of conditions characterised by discomfort or persistent pain in muscles, tendons and other soft tissues, with or without physical manifestations. It is usually associated with tasks which involve: 1 repetitive or forceful movement or both; and/or 2 maintenance of constrained or awkward postures. (Definition from National Code Of Practice or the Prevention Of Occupational Overuse Syndrome, NOHSC, 1994) Repetition involves repeating the same movement over a prolonged period, particularly when the action is undertaken in a hurry, in an uncomfortable position or when there are sudden increases in activity. The amount of force required to undertake an activity and the amount of tension from awkward movements can contribute to OOS. The lack of rest breaks can worsen any condition that may lead to OOS. Preventative and control measures include: setting work rates at realistic capacities for the individual providing a variety of work in the job design limiting fixed postures and highly repetitive movements by varying tasks increasing the number of shorter work pauses rather than having longer work pauses designing equipment for height, reach and tilt variations having a well-designed layout for free movement in the work area. It is important to recognise when your body is stressed or suffering from muscle fatigue, and to give those muscles a rest. Periods of sitting should be interspersed with periods of walking and stretching. ERGONOMICS Ergonomics is the study of the interaction between humans and the working environment. It aims to promote the safety of workers. For example, making simple changes to work methods, equipment and layout can help to prevent OOS. Ergonomics includes: the design and adjustment of support furniture the immediate surroundings of light, noise and temperature the scheduling of work loads. When attention is paid to the ergonomic design of a workplace there are many benefits, including: increases in your work efficiency decreases in errors due to fatigue reduction of health and injury problems 195 Version 2 TPC Janine Ratcliffe increase in work satisfaction. 2010 The workstation Careful placement of your desk and chair and keyboard, monitor and mouse are essential for a good working environment. You need to position a keyboard, mouse and monitor so that your body isn’t placed under stress, especially as these devices are often used for long periods. The following diagram shows the correct way you should sit when using a computer. Notice how the monitor is positioned in relation to the person’s eye level. Figure 1: Sitting correctly at a workstation An ergonomically sound workstation is one that is set up specifically to meet the OHS needs of an IT worker. You may spend many hours sitting, gazing at monitors and keying in information, so if the equipment that you use is not set up correctly, it can cause OOS problems. The equipment you use may include the: monitor chair keyboard desk. How you sit (your posture) and whether you move around (your mobility) also play a role in preventing OOS. However, it is currently believed that variety and movement are the keys to injury prevention rather than exact posture. 196 Version 2 TPC Janine Ratcliffe The monitor 2010 The monitor (VDU or screen) is your page. If your monitor is poorly set up, it can cause eye strain. When sitting at your monitor, make sure that in general you can see all text and graphics on the screen clearly without having to peer at them, lean forward or strain. The most important aspects of setting up the monitor to avoid eye strain are to make sure glare and reflections are not a problem. Eg, if a window is behind or in front, it can cause eye strain. So the position of the monitor in the room, and adjusting blinds or lighting to reduce or redirect strong light sources are important things to consider. You can also make adjustments to the monitor control settings, such as contrast and brightness, and to font size and screen resolution — to improve the readability of text and graphics on a screen to suit your needs. When setting up your monitor, you need to: position the monitor (or adjust other conditions in the room) to avoid glare and reflections on the screen check for screen flicker position the monitor at the correct distance and height set up, adjust and clean the display set up the display and screen resolution of your computer to facilitate comfortable viewing check again the lighting conditions and for any reflections. Tiredness can also be caused by other problems with your workstation setup or poor posture. It can also result from long work sessions. If you think you may have eyesight problems, it is important to get your eyesight checked by your doctor or an optometrist, as screen work tends to aggravate existing eye problems. If you normally wear glasses or contact lenses, you should wear them when working at your computer. 197 Version 2 TPC Janine Ratcliffe 2010 Practise setting up your monitor 1 Check your distance from the monitor Eye strain can be reduced by working at the correct distance from the screen. The ideal distance from your eyes to the monitor screen is as far away as possible, but close enough for work to remain legible and in keeping with good posture. This is generally further than the conventional 35 to 75 cm. If you wear glasses, they should have this focal length. Reading glasses are generally unsuitable for monitor work, unless the screen is specially placed for their line of vision and focal length. The vertical orientation of the screen means that people with bifocals may have problems. Creating distance between you and the monitor will also minimise your exposure to radiation and any potential danger this may cause. 2 Check the height of your monitor Eye strain, back, neck and shoulder pain can be reduced by choosing the best height for the monitor. How high your monitor is depends on your individual physiology and personal choice. Traditionally, monitors have been positioned so that the top of the screen is at eye height. This is the highest the monitor should be, and many people will find it more comfortable to have the monitor at a lower level. Generally the centre of the screen should be a maximum of 20 degrees below the horizontal line of vision. You can raise the height of the screen with a phone book if required. 3 Change your display set up, if necessary Eye strain can be reduced by selecting a two-coloured screen. On a PC, select Start on the toolbar then Settings, then Control Panel and then Background. On a Mac, select the apple on the toolbar, then Control Panels, and then Appearance. If you spend many hours in front of a computer screen each day, a two-coloured screen (for example green on black) is less fatiguing to the eyes than a screen with many colours. 4 Change your screen resolution, if necessary Eye strain can be reduced by adjusting the screen resolution and font size. On a PC, select Start on the toolbar, then Settings, Control Panel and then Settings. On a Mac, select the apple on the toolbar and then Control Panels and then Monitors and Sound. You usually have some choice of screen resolution: 640 x 480 (basic VGA) 800 x 600 (basic SVGA) 1074 x 768 1280 x 1024, etc. If you run at the higher figures, you may also have a choice of large fonts or small fonts. 198 Version 2 TPC Janine Ratcliffe 2010 Although higher resolution gives you more material on screen, which can be useful, some monitors can’t produce a sharp display at the higher resolutions. Even if they can, small fonts, however sharp, can be difficult to read. Experiment with resolution and font size to find a combination that you are comfortable with for long working sessions. 5 Adjust the monitor brightness and contrast taking sharpness into account Eye strain can be reduced by correcting contrast and brightness and having a clean monitor screen. On a PC, your contrast and brightness settings are on the monitor. On a Mac, select the apple on the toolbar and select Control Panels and then Monitors and Sound. The main purpose of these controls is to adjust brightness and contrast for comfortable viewing, but on many cheaper monitors, these controls can also affect the sharpness of the screen display. If you turn the controls right up, you may find that characters become blurred. Keep the screen clean. Dust and fingerprints reduce the effective sharpness and contrast of the screen and, over a long session, make it more likely that you’ll end up with some form of visual fatigue. It’s a bit like driving long distances with a dirty windscreen. 6 Avoid setting up the monitor with a light or a window behind you. Eye strain can be reduced by having the screen at eye level and reducing ceiling light. Tilting the screen upwards may also cause ceiling lights behind you to reflect on the screen. If the lighting near your work space isn’t uniform, you may experience: ‘bright spots’ (such as artificial lights or a brightly lit window) in your field of view reflections on the screen which make it more difficult to resolve the actual screen contents so that your eyes have to work harder. Some people are adversely affected by fluorescent lighting. It can exaggerate the effect of screen flicker. If you’re sensitive to this flickering, you should try to set up your workstation in an area where the lighting is natural or incandescent. Monitors are now commonly available with anti-glare or anti-reflection screen coatings that can be quite effective compared with the older style of shiny, plain glass. Some people with epileptic conditions can be badly affected by screen flicker on computers. If you have such a condition, you should be particularly careful in setting up the screen and lighting conditions for the workstation. Also seek medical or other specialist advice. Other methods to prevent eye strain Setting up your monitor correctly is not the only way to prevent eye strain. You can also help prevent it by doing exercises, relaxing and making sure your environment is comfortable. 199 Version 2 TPC Janine Ratcliffe 2010 Check the atmospheric conditions Make sure the humidity and temperature of your working environment is comfortable. Some air conditioning and some heating systems can generate very dry conditions. Even when not working at a computer, some people find their eyes are affected by being in a dry atmosphere for lengthy periods. This problem may be made worse if you have a visually intensive task in which you don’t move your eyes or blink much. Having some pot plants in the office can help to humidify the atmosphere. Be relaxed and comfortable Make sure you’re relaxed and physically comfortable at the computer. Think about how you make your own study or work environment comfortable. For example, you may listen to music while studying. Do eye exercises To prevent getting eye strain while studying or working long hours, do eye exercises at least every 20 to 30 minutes. Practise these eye exercises now. Blink: lightly and fast ten times. Look at the computer monitor (or read a page of text) and then refocus on something further away for 5-10 seconds. You need to change the focal distance of your eye frequently to reduce eye fatigue. Looking out a window, at a picture with a distant focal point or a view into another room will help. You should do this three times each break. Stretch your eyes: close your eyes and move them around as if looking all around you — up, right, down, left, then slowly from left to right or up to down. Rest your eyes: shut your eyes and then cup your hands over them and rest in the dark for 30 seconds. Monitors and radiation You may be concerned about the possible health hazards of radiation from monitors. Typically, exposure to electric and magnetic fields from monitors is relatively low and similar to the radiation that may come from radios and other devices found in your home. They are also generally less than many limits developed for radiation protection purposes. However, if you are worried, here are some tips: Office partitions will not shield users from some types of emissions. Work spaces should be designed so that no one in an adjoining area is within 1.5 metres of the sides or back of a monitor in someone else’s work area. Laptop computers use liquid crystal display screens that produce smaller amounts of radiation. Research suggests that old, malfunctioning or multiple monitors will not cause increased exposure. Now that you have adjusted your monitor it is important to check that it is set up in the correct way. 200 Version 2 TPC Janine Ratcliffe 2010 Checklist for setting up a monitor Is the screen as far away from your eyes as possible while remaining legible? Is the screen positioned to minimise strain on your neck and back? The screen should be below eye level. As a rule of thumb the top toolbar on most screens should be at eye level. Have the screen display and resolution been set up to minimise eye strain? While some combinations are less fatiguing than others, the ultimate choice of these is personal. Is the computer screen clean? Is the screen display stable with no flickering? Are the characters large enough to be easily read? Is the screen mounted on a swivel base and is it angle-adjustable? If adjusted and situated properly this can reduce glare and reflections coming from it. Do you need an anti-glare filter? The chair IT jobs often involve sitting for long periods. If you sit for long periods, you are at risk of back disorders. The two greatest problems seem to be: 1 sitting upright or forward 2 not changing position. The type of chair you have will help you to prevent OOS problems, if you adjust and use it appropriately. You must make sure you have an ergonomic chair. Don’t just get a dining room chair or some old office chair which can’t be adjusted correctly. A swivel chair with a five-point base on castors is stable, free-moving and will allow easy access to any material around you. If you are mainly doing keyboard work, a chair with no arms, or with hinged or removable arms, enables you to get as close to your work as necessary. If the chair has armrests, they should be low enough to fit under the desk. The seat of the chair should be made of cloth, be broad, have firm packing and be curved or waterfall-shaped at its front edge to reduce the risk of localised pressure to the thighs. It should transfer weight through the buttocks, not the thighs. Chair adjustments If you are moving around in your chair (and you should be), you will need to adjust your chair. In other words, the chair should follow you, as you change posture. The most important chair adjustments are: Seat height from the floor — the feet should be able to rest flat on the floor. However, this doesn’t mean the feet should always be flat on the floor. Legs should be free to stay in different positions. Depth from the front of the seat to the backrest — you should be able to use the backrest without any pressure behind the knees. For talking and 201 Version 2 TPC Janine Ratcliffe 2010 interviewing, the angle of the backrest should be 10 to 20 degrees back from the vertical. Lumbar support height — every person is shaped differently but aim to support the lumbar part of your spine. Posture Your posture can prevent back damage. You should follow these tips. Do not sit absolutely upright all the time. It is OK to sit with your hip joints somewhat straightened in a supported slouch. Sit in a slightly reclined position at least part of the time. You need to be familiar with good posture when working at a computer all day. The traditional idea of ‘good posture’ is to sit upright. There is a lot to be said for balancing the weight of the head on top of the spine, because this avoids the static muscle loading and tension associated with postures where the weight of the head is not balanced above the spine. However, there are also benefits in a slightly reclined posture. It is not a good idea to sit with an absolutely upright posture all the time when seated at your computer, as an upright posture with a 90 degree hip position, if unrelieved by variations in posture, is actually unhealthy for certain discs in the back. It is a good idea to spend at least part of the time sitting with your hip joints somewhat straightened in a supported slouch. It may be more healthy in the long run. Forward-tilt chairs support this posture, but so do chairs with level seats and reclined backrests. Sitting in a slightly reclined posture puts more of your weight onto the chair’s backrest. If the chair backrest holds up more weight, the discs in the lower back hold up less weight. (Well-designed armrests also take some of the upper body weight from the discs.) Reclined sitting lets the back muscles relax. Keep active You should move around. As well as helping the muscles relax and recover, this alternately compresses and decompresses the intervertebral discs, which results in better filtration of fluids into and out of the cores of the discs. Discs stay plumper and, in the long run, healthier. Foot position Your feet should rest on the floor (even when extended), one slightly in front of the other. You should keep your legs moving by changing position as much as possible. Sometimes in achieving the correct height for your arms, your feet are no longer supported, so use a footstool or two phone books taped together to give them the support they need. Footstools have their problems, however, as they limit the variety of placement for your feet. Keep a posture chart, such as the one shown in Figure 1, taped to the table or pinned to the wall near to your computer, as a reminder of the ideal posture. 202 Version 2 TPC Janine Ratcliffe The keyboard 2010 Apart from gazing at the monitor, the other activity most IT workers are doing repetitively is keying in information. The following information should help you to avoid OOS. When keying, your hands should float freely above the keys, much like a piano is played. An appropriate wrist rest, one that is not too thin, too thick, too hard or with sharp edges, may be used to give extra support when not keying. Make sure your head is not bent too far forward to see the screen. 203 Version 2 TPC Janine Ratcliffe 2010 Keyboard placement Place the keyboard on the desk directly in front of you and in front of the screen to encourage correct work posture. Make sure the forearms are supported, the wrist is kept straight. Make sure the elbows aren’t resting on anything hard or sharp. The keyboard should be in the same plane as the forearm. Aim to keep the mouse as close to the keyboard as possible. If you prefer to work with the keyboard away from you, your desk should be higher than elbow height. Figure 2: Keyboard placement for sitting at a workstation Document holder If you are typing from a document, use a document holder to lift the height of the documents being read. Rest periods If you are continuously writing or keying, make sure you have a short break (5– 10 minutes) each hour. Some say that a 30-second break every ten minutes is preferable. The exact length of the break will depend on the intensity of the work you’re doing. The break could involve doing another activity related to the work, such as making phone calls or doing exercises to refresh and relax the muscles. Rule of thumb: whatever you do often and for long periods of time, do the opposite during a break and move around. For example, playing card games on your computer during your breaks means you are not having a proper break from the constraints of working at the computer. Now adjust your own keyboard and personal practices from what you have learnt. Keyboard skills It is important to have well-developed keyboard skills. Your company may have a set of guidelines about speed and accuracy that you must be able to achieve. Obtain a copy of touch typing tutorial software such as Mavis Beacon or Typequick. Use the tutorial package as much as possible to improve your typing 204 Version 2 TPC Janine Ratcliffe 2010 ability. Try to spend 30 minutes at the beginning of each study session on touchtyping until you are proficient. The more you practise the better your keyboarding skills will be. If you can teach yourself to touch type then your productivity with using the computer will increase dramatically. It is far better for your fingers if you are typing with all fingers than with just one or two and putting a lot of strain on them. Inside the Keyboard A keyboard is a lot like a miniature computer. It has its own processor and circuitry that carries information to and from that processor. A large part of this circuitry makes up the key matrix. The microprocessor and controller circuitry of a keyboard The key matrix is a grid of circuits underneath the keys. In all keyboards (except for capacitive models, which we'll discuss in the next section), each circuit is broken at a point below each key. When you press a key, it presses a switch, completing the circuit and allowing a tiny amount of current to flow through. The mechanical action of the switch causes some vibration, called bounce, which the processor filters out. If you press and hold a key, the processor recognizes it as the equivalent of pressing a key repeatedly. When the processor finds a circuit that is closed, it compares the location of that circuit on the key matrix to the character map in its read-only memory (ROM). A character map is basically a comparison chart or lookup table. It tells the processor the position of each key in the matrix and what each keystroke or combination of keystrokes represents. For example, the character map lets the processor know that pressing the a key by itself corresponds to a small letter "a," but the Shift and a keys pressed together correspond to a capital "A." The key matrix A computer can also use separate character maps, overriding the one found in the keyboard. This can be useful if a person is typing in a language that uses letters that don't have English equivalents on a keyboard with English letters. People can also set their computers to interpret their keystrokes as though they 205 Version 2 TPC Janine Ratcliffe 2010 were typing on a Dvorak keyboard even though their actual keys are arranged in a QWERTY layout. In addition, operating systems and applications have keyboard accessibility settings that let people change their keyboard's behavior to adapt to disabilities. From the Keyboard to the Computer As you type, the processor in the keyboard analyzes the key matrix and determines what characters to send to the computer. It maintains these characters in its memory buffer and then sends the data. A PS/2 type keyboard connector. Many keyboards connect to the computer through a cable with a PS/2 or USB (Universal Serial Bus) connector. Laptops use internal connectors. Regardless of which type of connector is used, the cable must carry power to the keyboard, and it must carry signals from the keyboard back to the computer. Wireless keyboards, on the other hand, connect to the computer through infrared (IR), radio frequency (RF) or Bluetooth connections. IR and RF connections are similar to what you'd find in a remote control. Regardless of which sort of signal they use, wireless keyboards require a receiver, either built in or plugged in to the USB port, to communicate with the computer. Since they don't have a physical connection to the computer, wireless keyboards have an AC power connection or use batteries for power. 206 Version 2 TPC Janine Ratcliffe 2010 Microsoft wireless keyboard This Microsoft wireless keyboard is battery-powered. Whether it's through a cable or wireless, the signal from the keyboard is monitored by the computer's keyboard controller. This is an integrated circuit (IC) that processes all of the data that comes from the keyboard and forwards it to the operating system. When the operating system (OS) is notified that there is data from the keyboard, it checks to see if the keyboard data is a system level command. A good example of this is Ctrl-Alt-Delete on a Windows computer, which reboots the system. Then, the OS passes the keyboard data on to the current application. The application determines whether the keyboard data is a command, like Alt-f, which opens the File menu in a Windows application. If the data is not a command, the application accepts it as content, which can be anything from typing a document to entering a URL to performing a calculation. If the current application does not accept keyboard data, it simply ignores the information. This whole process, from pressing the key to entering content into an application, happens almost instantaneously. To learn more about computers and keyboards, check out the links on the next page. 207 Version 2 TPC Janine Ratcliffe 2010 BASIC COMPUTER MAINTENANCE: CLEANING AND MAINTAINING COMPUTER EQUIPMENT Particular care must be taken when cleaning computer equipment. Before cleaning any electrical equipment make sure that it’s switched off and unplugged from the mains. This is important, because if there’s a short circuit or malfunction in the equipment it could still be ‘live’ and result in an electric shock and possible death. Allow certain equipment, such as monitors and laser printers, to cool down and lose their capacitance before cleaning them. You should leave monitors switched off for at least 30 minutes before cleaning the outside of them, and laser printers switched off for at least 30 minutes before cleaning inside them. If you’re cleaning inside a PC, or you’re going to handle parts from a PC such as hard disks or circuit boards, you should earth yourself using an antistatic earthing wrist strap. Always refer to the manufacturer’s manual before attempting to clean any equipment, because improper cleaning or maintenance may be dangerous and also may invalidate your warranty. Some equipment, such as power supplies and monitors, use large voltages and therefore should only be maintained by people specially trained. It could be dangerous for anyone else to open them for maintenance. 208 Version 2 TPC Janine Ratcliffe Electrical hazards 2010 As a new employee, your employer, or OHS Officer, should ensure that you are given instructions for dealing with electrical hazards in your workplace. Take special note: Always turn off the power at the power point and disconnect the lead. Just turning off the switch on the peripheral isn’t enough. It will still contain 240V. Avoid overloading a power board or power point. Whilst most computer equipment doesn’t use more power than a power point can handle, you shouldn’t connect any high power appliances, such as heaters, to the same power point or power board. Ideally, the computer should have its own power point. Where you need to use extension leads or power boards, make sure they’re not damaged, and if possible use ones with safety switches fitted. Don’t poke tools into any peripheral device. Apart from doing damage to the device, you could also hurt yourself. For example, the voltages in the rear of a typical monitor can exceed 25 000 volts (yes, 25 thousand)! Lethal voltages also exist in many other types of peripherals. Make sure that there’s no water or other fluid in an area where a peripheral device is to be stored, installed or used. As fluids conduct electricity, they can both damage the device and endanger the user. Earthing strap Earthing straps should be used if you need to touch components inside a computer. The next screen explains how to use this strap. The antistatic wrist strap wraps around your wrist, and is then connected to the outer casing of a PC (which is, of course, switched off and unplugged from the mains). If you need to switch the PC back on you must first detach the strap. The earthing strap also protects the equipment because there is enough charge in your body to damage the sensitive electrical components in the equipment. 209 Version 2 TPC Janine Ratcliffe 2010 Figure 3: Earthing strap Cables Even though the outside of a cable may appear undamaged, the wire inside may be broken, which will make it inoperative. The following screen has instructions for care of cables. Don’t twist or wind cables up tightly and avoid routing them around sharp objects or corners which could eventually wear through the insulation. Power leads can be lethal if damaged in this way. Figure 4: Take care not to bend cables too sharply or route them around sharp corners. Frayed cords don’t have protective coating around the electrical wires. This is very dangerous. You may get an electric shock if you touch frayed cord. Report frayed cords to your supervisor. The cord should be replaced. Before installing any computer equipment, always conduct a visual inspection of any cables and connectors to be used, and replace any that appear to have been damaged. Connectors Always make sure you check for damaged connectors and use the correct methods for plugging and unplugging them. When you’re plugging a connector into a socket, always make sure that you line it up so that the pins can slide easily into the holes, without bending. A common fault is a single bent or broken pin, as seen the figure, which can be difficult to trace. Always visually check the pins in any connectors before plugging them in. Never plug a cable into a machine that is turned on. There is a risk of electric shock to the user and damage to the equipment due to the power surge. 210 Version 2 TPC Janine Ratcliffe 2010 Figure 5: Take care not to bend pins Once you have plugged in the connector, tighten the screws by hand. Don’t over tighten these screws, as you may damage the connector, or make it difficult to remove. Figure 6: Don’t over tighten screws When removing a connector, never pull it by the cable. First loosen any screws, and then, holding the body of the connector, gently rock and remove the connector. If it doesn’t come out, check that the screws have been loosened fully, then try again. Figure 7: The right way to remove connectors Some devices use an IEC connector for connection to the 240V power supply. An example is the backplane of the system unit, which has both a male and a female IEC connector, one to connect to the 240V power supply, and the other for connecting a monitor power lead. Figure 8: IEC connectors IEC connectors don’t have tightening screws, but rely on friction to hold them in place. Sometimes they may need to be wriggled in or out of place quite firmly. SUMMARY You now have knowledge of the basic ergonomic requirements for setting up a workstation.

The demand for worms seems to have levelled off, so they're hoping to develop new markets by selling over the Web. Kim, an enthusiastic Web designer, has been employed but the PCs that are available are getting a bit old and can't handle the new software that Kim will need. Because the Whoppa Worm Company is out in the bush they'll be depending on phone and mail order and will use the newspaper and magazine advertisements to get an idea of what they can get. The PC Kim needs will have to: handle multiple applications at the same time handle graphics have a high quality screen have a portable storage device that's bigger than a floppy to enable Kim to work at home. Assignment Tasks By looking at advertisements for computer systems in newspapers, find systems that will suit each of these situations. You are required to: 1 identify the requirements and constraints of the given situation 2 create a table showing the components for each system. Headings: Component, Component details 3 explain how each system meets the requirements and constraints. 232 Version 2 TPC Janine Ratcliffe 2010 Activity 10: PC System Boot Sequence – Cloze Passage The Boot sequence is the first operation performed by a computer when it is turned on or reset. The Boot sequence basically tells the computer what operating system it uses and how to go about loading it. The system BIOS is what starts the computer running when you turn it on. The following are the steps that a typical boot sequence involves. 1. The internal power supply turns on and _________________. 2. The processor, which is suffering from ______________ looks in the system ROM for the start of the BIOS boot program which contains a "jump" instruction telling the processor where to go to find the real BIOS startup program. 3. BIOS performs the power-on self test (________). 4. BIOS looks for the _________ card. 5. BIOS then looks for other devices, eg the hard _______ drive. 6. BIOS ___________ the startup screen. 7. BIOS does the memory count-up test which you see on the_________. 8. BIOS performs a "system inventory" to determine what ________ of hardware is in the system. 9. BIOS searches for and labels logical devices (______ and LPT ports). Word List amnesia boot COM configuration disk displays error initialises operating Plug and Play POST Screen sort video 10. BIOS detects and configures _________________ devices at this time and displays a message on the screen for each one it finds. 11. BIOS displays a summary screen about your system's _____________. 12. BIOS begins the search for a drive to _______ from. (A, C, or even D). 13. BIOS looks for a master boot record 14. BIOS starts to boot the _______________ system. If the first device that the system tries (floppy, hard disk, etc.) is not found, the BIOS will then try the next device in the boot sequence, and continue until it finds a bootable device. 15. If no boot device at all can be found, the system will normally display an ________ message and then freeze up the system. What the error message is depends entirely on the BIOS, and can be anything from the rather clear "No boot device available" to the very cryptic "NO ROM BASIC - SYSTEM HALTED". This process is called a "cold boot" (since the machine was off, or cold, when it started). A "warm boot" is the same thing except it occurs when the machine is rebooted using {Ctrl}+{Alt}+{Delete} or similar. In this case the POST is skipped and the boot process continues roughly at step 8 above. 233 Version 2 TPC Janine Ratcliffe Unit Guide Unit Title: Use computer operating system Unit Code: ICAU2231A Version Number: 2010 1 Implementation Date: 01-Jan-2007 Unit Sponsor: Business Arts and Info Tech Product Developer: Business Arts and Info Tech Program Area: Information Services Product Level: Available For Statewide Delivery Last Updated: 10-Mar-2008 Nominal Student Teacher Hours: 20 Nominal Student Hours: 20 The Unit Guide supports delivery of this unit of competency.

UNIT OF COMPETENCY INFORMATION 2.1 Unit Descriptor This unit defines the competency required to configure, use and optimise a computer operating system. The following unit is a prerequisite for this competency: ICAU1128A Operate a personal computer There may be benefit in concurrent learning of the following unit: ICAU2005A Operate computer hardware These units are linked and form an appropriate cluster: ICAU2005A Operate computer hardware 2.2 Elements of Competency and Performance Criteria Elements describe the essential outcomes of a unit of competency Performance Criteria describe the required performance needed to demonstrate achievement of the element. Where italicised text is used, further information is detailed in the required skills and knowledge and/or the Range Statement. Assessment of performance is to be consistent with the Evidence Guide. ELEMENTS PERFORMANCE CRITERIA 1. Configure operating system 1.1 Configure operating system to suit the working environment, including but not limited to setting variables 2. Use operating system 2.1 Install, upgrade and uninstall application software to suit the working environment 2.2 Use both the graphical user interface and the command line interface to perform basic tasks 3.1 Use operating system and third-party utilities 3.2 Customise the graphical user interface 3.3 Use techniques unique to the command line interface 4.1 Set up input and output devices and check functionality 4.2 Install drivers as appropriate and check functionality 3. 4. Optimise operating system Support input and output devices 2.3 Range Statement 236 Version 2 TPC Janine Ratcliffe 2010 The Range Statement contextualises the unit of competency and provides a focus for assessment. The information provided is intended to define the scope of assessment and to assist assessors define the performance to be achieved by an individual in the workplace. The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Italicised wording in the Performance Criteria is detailed as follows. VARIABLE SCOPE Operating system May include but is not limited to Linux 7.0 or above, Windows 2000 or above, Apple OS X or above. Application software May include databases, word processing, email, internet browsers, system browsers and spreadsheets. Third-party utilities May include but are not limited to disk scanning, partitioning and defragmenting, backing up data, recovery and diagnostic tools. Input and output devices May include but are not limited to keyboard, mouse, printer, scanner, monitor and modem. 2.4 Evidence Guide The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required skills and knowledge, the Range Statement and the assessment guidelines for this Training Package. Critical aspects of evidence Assessment must confirm the ability to use an operating system in a variety of scenarios and across all functions including (1) scheduling, loading, initiating, and supervising the execution of programs; (2) allocating storage; (3) initiating and controlling input/output operations; and (4) handling errors. Knowledge and skills Knowledge includes: Function of single-user and multi-user operating systems Compatibility of an operating system, in respect to other versions Interoperability between operating systems Software applicable to the operating system Skills include: Configure, use and optimise operating system Install and support peripheral devices Create users for a multi-user system Apply user changes for a multi-user operating system Set passwords for different users Assessment guidance The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1. Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated 237 Version 2 TPC Janine Ratcliffe environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency. 2010 Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario. In the case of this unit, it could be assessed in a holistic manner with: ICAU2005A Operate computer hardware Resources To demonstrate competency in this unit the person will require access to: Workstation Operating system Software configuration guides Documents detailing operating system control panel and configuration data An introduction to the command line at this level would be appropriate to prepare the person for concepts related to directory structure, folder hierarchy and path relationships. Role context The operating system (OS) program is the first program loaded into the computer by a boot program and it remains in memory at all times thereafter. It is strategically placed in that it manages all the other programs in a computer including the allocation and usage of hardware resources such as memory, central processing unit (CPU) time, access and security, hard disk space, and peripheral devices (like speakers or a mouse). The OS is the foundation software on which other programs, such as Word or Excel, depend. These other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI). Operating systems come in a variety of forms. Most use a graphical user interface (GUI) and some use command line; others have a combination of both. It is appropriate for the person to grasp the fundamentals of both the GUI and the command line interface to prepare them for advanced concepts should they chose to enter learning towards a more advanced unit of competency. The breadth, depth and complexity of knowledge and skills in this competency would prepare a person to perform in a range of varied activities or knowledge applications where there is a clearly defined range of contexts in which the choice of actions required is usually clear. There would generally be limited complexity in the range of operations to be applied. Performance of a prescribed range of functions involving known routines and procedures and some accountability for the quality of outcomes would be characteristic. Applications may include some complex or non-routine activities involving individual responsibility or autonomy and/or collaboration with others as part of a group or team. An individual demonstrating this competency would be able to: Demonstrate basic operational knowledge in a moderate range of areas Apply a defined range of skills Apply known solutions to a limited range of predictable problems Perform a range of tasks where choice between a limited range of options is required Assess and record information from varied sources 238 Version 2 TPC Janine Ratcliffe Take limited responsibility for own outputs in work and learning 2010 Additionally, an individual demonstrating this competency would be able to: d. e. f. Understand a range of concepts and procedures related to operating systems Demonstrate theoretical knowledge of operating system set-up and configuration Apply changes to an operating system.

An operating system is a computer program that manages all the tasks that you perform on the computer. Every computer needs an operating system in order to run other programs. Operating systems perform many basic tasks including decoding input which has been sent from the keyboard or mouse, sending output to the monitor, keeping track of all files and folders on the computer and controlling devices that are attached to the computer such as printers and scanners. Today there are many different kinds of operating systems that are available. Some of the most popular include: 249 Version 2 TPC Janine Ratcliffe 2010 Microsoft Windows — a popular operating system that has been created by Microsoft Mac OS — designed and specifically used on Apple MacIntosh computers. Linux — a freely-distributed operating system. When you buy a computer the operating system has usually been installed. Sometimes, however, you may need to change some basic settings to suit your requirements. Most operating systems usually have a special area that allows you to configure settings such as changing as the mouse buttons, creating an internet dial up connection, setting up a printer or scanner, organising the start menu, setting the date and time and managing user accounts. In many operating systems, configuring these settings can be done in a place called the Control Panel. CONFIGURING MOUSE SETTINGS A mouse is a very popular device that you use to point to images on the screen and to ‘click’ on the chosen image. A mouse usually has two buttons at the top and often a scroll wheel between the two buttons. Some of the popular ways a mouse can be used include: Moving: on a flat surface you can move the mouse in the direction you want to go. Clicking: to quickly press and release a mouse button in order to select an item. Double-click: to click the mouse quickly twice, will often open a particular item. Drag: to hold the mouse button while moving the mouse will allow you to move something from one place to another. If you have never used a mouse before, it could feel difficult to start with. You may also have problems using the mouse if you are left-handed. Configuring settings such as mouse speed and changing the buttons may be helpful. All operating systems will have a slightly different way of changing the mouse, however, you will find in most operating system the mouse settings can be configured somewhere inside the Control Panel (or Control Centre). Changing buttons If you are a left-handed you may need to configure your mouse so that the main button you press with your left hand is the right mouse button. Changing the speed of the mouse There should also be settings available that allows you to change options such as the double-click speed and how fast the pointer will move on the screen. 250 Version 2 TPC Janine Ratcliffe 2010 Figure 1: Changing Mouse Properties using Microsoft Windows operating Figure 2: Changing Mouse Properties using an Apple MacIntosh operating system 251 Version 2 TPC Janine Ratcliffe 2010 Figure 3: Changing Mouse Properties using a Linux operating system SETTING A DIAL UP CONNECTION A dial-up connection connects you to connect to a network or the Internet by using a device that uses a telephone network. This device is often a modem that uses a standard phone line. A dial-up connection is one method of connecting to the Internet, however, in recent times a connection called broadband is a faster alternative. If, for example, you worked for a company that allowed you to use your computer from home, you may need to create a dial up connection so that you can connect to the company’s computer system. You will need a user name, password and telephone number in order to create this kind of dial-up connection. You may need to create a dial-up connection so that you can connect to the Internet. Before you can connect to the Internet you will need to find yourself an Internet service provider (ISP). Internet service providers are organisations that offer businesses and individuals access to the Internet. For a fee, the ISP will provide you with an account, password and telephone number that allows you to access the Internet. Similarly to changing the mouse settings, a dial-up connection is usually created inside the Control Panel. Information that you will probably need to enter includes: The name of the connection you are creating — you may want to use the name of the Internet Service Provider. The modem type — you may be asked for the name of your modem and the maximum speed it can handle. You will need to refer to the modem’s user guide to help you. A user name, password, server address and telephone number (if connecting to the Internet — your Internet service provider should give you this information). Some operating systems also include wizards, which are step-by-step guides to help you through the process of setting up a dial up connection. The following three diagrams display the Windows XP operating system’s wizard for setting up a dial-up connection. 252 Version 2 TPC Janine Ratcliffe 2010 Figure 4: Windows XP operating system’s wizard to create a new dial up connection SETTING UP PRINTERS AND OTHER EXTERNAL DEVICES Printers A paper copy of a document is often known as a hard copy. Software programs, on the other hand, are known as soft copies. If you have a printer attached to your computer you can print any document or picture you created on the 253 Version 2 TPC Janine Ratcliffe 2010 computer or information you find on the Internet. If you are part of a large organisation it could be possible that there are several printers that you can use for printing. Within the Control Panel there will probably be an option to choose Printers. The Printer’s option may allow you to change a lot of printer settings including: making the printer the default printer (the printer that will be used if no other printer is selected) page orientation — whether the printouts will be portrait or landscape whether the printout will be colour or greyscale (black and white) print quality — whether the print out will be draft, normal or best quality paper size — eg A4, A5, letter the ability to cancel or pause the job that is currently printing. Figure 5: A Windows dialog box that enables changing printer preferences Other external devices Depending on the operating system you are using there may also be an option to change settings for input devices such as scanners and digital cameras. Some of the settings that may be able to be changed include: the quality of scan colour of images (colour or greyscale) page orientation (landscape or portrait). Shortcuts to accessing programs or files Shortcuts are used in a windows-based operating system. They are quick pointers to programs and files on your computer. They allow you to open a program or a file by double-clicking on them. Shortcuts have an arrow in the lower left-hand corner of the icon. A shortcut can be placed anywhere on your system. The most common places to place shortcuts are on the desktop and on the Start menu. One method to create a shortcut on the desktop is to: 1 Choose the program or file that you want to use for a shortcut. 2 Right-click with your mouse button. (Left-click if you have swapped your mouse settings for a left-handed person.) 254 Version 2 TPC Janine Ratcliffe 2010 3 Choose Option ‘Send to Desktop’. (Create Shortcut) will appear. Or, Create Shortcut may be listed in the menu that pops up when you rightclick. In either case, select Create Shortcut. 4 An icon similar to below will appear on your desktop. 255 Version 2 TPC Janine Ratcliffe Start menu 2010 Like shortcuts, the Start menu is an option that is used within the Microsoft Windows operating system. A Start menu is a menu that allows you to access useful items on your computer. A list of programs that you use the most frequently will appear in this list. This list can be changed manually by: 1 Using your mouse, right-click within the Start menu. 2 Go to Properties. There will then be options such as size of icons, number of programs to display that you can customise. Figure 6: An example of the Start menu in Windows XP SETTING DATE AND TIME Your computer needs to use the date and time for a large number of operations. For example, every time you create or modify a file the date and time is set alongside the file. Whenever you send an email the date and time is sent with the email. There is also a clock available that will display the current date and time. All operating systems will have a place for you to set up the date and the time. If you have a Control Panel or Control Centre the date/time settings should be located in that area. There may also be a place to change the ‘time zone’, so if you took the computer to another country you could automatically adjust it to the new time zone. Some operating systems will also let you change the way the date and time appears. You could, for example, set the time to appear in 24 hours format or 12hour format using AM and PM. 256 Version 2 TPC Janine Ratcliffe 2010 Figure 7: Date and time using Windows Figure 8: Date and time using Apple MacIntosh CREATING AND CHANGING USER ACCOUNTS In some operating system software there is the ability to create user accounts for each person who will be using the computer. Benefits of creating a user account for each person are that this: customises the display of the desktop for each user keeps each user’s files private helps to protect important computer settings. When creating user accounts, one person needs to be an Administrator. The Administrator can have total control of the computer, meaning they can create or delete user accounts, install and delete programs — whereas the other users will not have this ability. To change or create a user account you will need to log in as an ‘Administrator’ and then you will probably need to go to the Control Panel and find the area User Accounts. All other users will have varying degrees of control of the computer. Administrators are able to set up each user independently. It is important that the administrator gives the correct amount of access to the computer system for each user. Depending on local needs, some users may need to be given accounts that allows them permission to install new programs and gives them complete access to all files on the computer. Other users, however, may only need accounts that will not let them change any settings and gives them access to only a limited number of files. The Administrator will also assign a password to each user’s account. Although the Administrator, will have permission to change a user’s password, it is important that each user keeps this password confidential, so that nobody else is able to use their account. The Administrator will also have their own password. It is essential that the administrator’s password not be lost or forgotten, for without access to an Administrator account, no changes to any other account will be able to be made. To change or create a user account you will need to log in as an ‘administrator’ and then you will need to go to the Control Panel and find the area ‘User Accounts’. In this area there will be the ability to create new accounts and make changes to existing accounts. 257 Version 2 TPC Janine Ratcliffe 2010 Figure 9: Example of accessing the User Accounts settings: Microsoft XP operating system SUMMARY An operating system is the most important program used on any computer. Today there are many ways in which you are able to configure the operating system to suit your individual needs. Basic configurations include: mouse settings, dial up connections, printer and other device settings, setting the date and time, and settings for user accounts.

Can you tell what day of the week this will be? Make sure that you reset your computer back to the current date and time. Activity 2 Bob and Michelle have two children, Joshua and Fiona. Everybody uses the same computer, however the children have accidentally been deleting some of Bob’s important work files. Bob is often away for long periods so Michelle will need to be able to install new software. What could they do to help restrict access to Bob’s files? Activity 3 Looking at your computer, can you find five programs or files that would be useful to have shortcuts to (so that you can access them from the desktop)? Explain why you chose each item to create a shortcut. 260 Version 2 TPC Janine Ratcliffe 2010 Task 2A The reading here will help you to develop your knowledge and skills in using an interface to perform basic tasks. This will involve an understanding of the basic features and tools available in a: graphical user interface command line interface. USE AN INTERFACE TO PERFORM BASIC TASKS Using a graphical user interface Using the mouse 261 262 What is the desktop? 49 Desktop windows 49 File management 264 Formatting a disk 265 Help 267 Searching 268 Command line interface 268 Drives and directories 269 Formatting 269 Wildcards and searching 270 Create, edit, copy and delete files 270 Help 272 Summary 272 Check your progress 272 USING A GRAPHICAL USER INTERFACE Today, the most popular kind of user interface is the graphical user interface. This type of interface is a lot easier for most people to use, compared to a command line interface. As the name suggests, a graphical user interface is very visual, and uses icons, buttons, menus, windows, boxes and colour to organise areas and tasks, and make commands accessible to the user. One of the most useful tools you use with a graphical user interface is the mouse. The mouse is the main way you move a cursor around the screen to select a button or icon to perform a particular task. Operating systems, such as Linux, have several different types of graphical user interfaces that are available for you to use. A popular Linux graphical user interfaces is called Gnome. 261 Version 2 TPC Janine Ratcliffe 2010 Figure 1: Screenshot of the Windows XP graphical user interface Using the mouse A mouse is a small, hand-operated device, and is one of the main ways to move the cursor and send commands to the computer. The cursor moves around the screen as you move the mouse. There are a variety of mice available. Some mice have two buttons (a left and a right mouse button), while some mice have three buttons. The left and right mouse buttons, however, are generally used by all operating systems. Sometimes it is necessary to use a combination of a mouse click and a key on the keyboard to perform an action. Where this is useful to do is mentioned in the following notes where relevant. Some common ways that you can use a mouse with two buttons include: Left-click: One click of the left mouse button allows you to choose something on the screen. Right-click: One click of the right mouse button will often open up a shortcut menu. Double-click: Quickly clicking the left button twice allows you to open a selected file or folder. Click-drag: Click on an item, such as a file icon, and keep holding the mouse button down, then drag the item to move it to a new location. Another common function that click-drag performs is with text. For example, when you are inside a word document, click at the start of a sentence and drag to the end of the sentence to select that sentence. If you have a mouse with only one button, then use that button to do all the things above you would do with the left mouse button. To open up a shortcut menu with this mouse on an Apple Macintosh computer, you press the Control key at the same time as you click once. 262 Version 2 TPC Janine Ratcliffe A mouse may also have the additional feature — a scroll wheel — that enables you to use the mouse to scroll up and down a window instead of using the window’s scroll bars. It can take a bit of practice to become skilful with all these mouse actions. 263 Version 2 2010 TPC Janine Ratcliffe What is the desktop? 2010 The desktop is the background screen that appears in an operating system. There are several useful items on the desktop including: Mouse Pointer: On the desktop the mouse usually appears as a small white or black arrow. When you move your mouse on a flat surface, the arrow will match the movement on the screen. Icon: An icon is a small picture that may appear on your desktop. Double-clicking on an icon is an easy way to open a program, files or other items (such as removable drives). Icons allow you a quick access to all of these items. Desktop windows It is very important to become familiar how to work with windows on the computer. A window is an area on the screen that displays programs or information, for example, windows are a device the operating system uses to display a list of the contents of a folder. A window can be moved, resized, opened and closed. Many operating systems allow you to have several windows open at any time, so you can easily move around between areas. Within a graphical user interface environment, windows are also used to display a document when it is opened. There are several features of windows including: Title bar: This is a bar that appears at the top of the window. It often includes the name of the program or folder. Minimise: This option shrinks the window to its smallest size. It will now only appear as an option on the task bar. The program is still open; clicking on it in the taskbar will restore it to its regular size. Maximize: This options makes the window expand to its largest size. Close: This will close the window. If you need to save your work, a program will usually ask you to save before closing. Minimise Maximise Close Figure 2: Buttons that appear in Microsoft Windows operating system to minimise, maximise and close a window. These buttons sit on the frame of each window. File management Any piece of information that needs to be stored permanently on the computer is stored as a file on a disk. There are many places that a file may be stored including a hard disk, floppy disk, USB disk or network disk. In order to manage all your files efficiently, most graphical user interfaces have a file management tool that will allow you to open, copy, delete, rename and move files from one location to another. All user interfaces have there own unique file management systems. 264 Version 2 TPC Janine Ratcliffe 2010 Microsoft Windows has several areas where you can manage the files including ‘My Computer’ and ‘Windows Explorer’. Within the Linux user interface, Gnome, files can be managed using the command line interface or a file manager such as ‘Midnight Commander’. Some common file management tasks are: Opening a file: A file can be opened by double-clicking on the file’s icon with the mouse. Copying a file: A file can be copied from one disk to another by clickdragging the file’s icon with the mouse. If you want to copy a file to another location on the same disk then you need to press the Command key (on a PC) or the Option key (on a Macintosh) at the same time you click-drag. Deleting a file: There may be several ways of deleting a file within a file manager. Clicking once on a file with the mouse and then pressing the Delete key on the keyboard is one method to delete a file. Renaming a file: Click on the file name or icon with the right mouse button and choose Rename to change the name of the file. Moving a file: Click-drag a file’s icon to move that file to another location. If you are moving the file to a different disk, eg from a hard disk to a floppy disk, the file is automatically copied to the floppy disk, so you would still have the same file left on the hard disk. Selecting more than one file at a time: You may want to delete, copy or move more than one file or folder within a window. To first select all the files/folders you want, press the Shift key on the keyboard each time you click on a file/folder that you want to add to the selection. Then, when all the items are selected, perform the next step: eg either click-drag anywhere on the selection to move everything or press the Delete key to delete everything in the selection. Formatting a disk Every computer operating system has its own way to organise the information on a disk. Each disk is divided into a number of tracks. Formatting a disk enables all previous information on the disk to be deleted; then the disk is prepared for use on the current operating system. Formatting can be useful tool to use if the disk has become corrupted, so that a clean disk is available to start again. Hard disk, floppy disks and USB disks are all able to be formatted using the same tool. Most floppy disks will already be formatted when purchased, but you can still re-format them. It can also be useful to give the disk a name, for example ‘MyStuff’. This can be done in a Microsoft Windows operating system, for example, by entering a name within the Volume Label when you are formatting the disk. 265 Version 2 TPC Janine Ratcliffe Figure 3: Screenshot of Microsoft Windows XP – Format tool 266 Version 2 2010 TPC Janine Ratcliffe Help 2010 Most graphical user interfaces supply some type of Help facility (or a number of Help tools) to provide assistance or additional information about features and functions of the operating system. Getting to know your Help tools is a good idea, as these can help you to keep learning more about the how to do tasks with your computer, and how to do them efficiently. In some user interfaces, the Help facility is contained within a separate menu on the desktop. However, Help may also be available within the windows of other functions (for example within the file management facility, search facility, format facility). Many user interfaces use the keyboard key F1 to bring up Help facilities instantly. The Help facility may contain boxes where you can enter text in order to search for specific information. The Help may also have topics of information so that you can find the general subject with which you need assistance. Sometimes the Help also can access information from the Internet, so the information is up-to-date. Figure 4: Screenshot of Microsoft Windows XP – Help and Support Center 267 Version 2 TPC Janine Ratcliffe Searching 2010 User interfaces usually also contain a function that allows you to search for files. This function will allow you to type in only part of a file name in order to try and find the file. You can also specify where you want to search for the file. If, for example, you know the file is on the hard disk, you can tell the search tool to look for the file within that area only. The search may also be advanced enough to ask you when the file was last modified and the approximate size of the file. Figure 5: Screenshots of Microsoft Windows – Search Companion tool COMMAND LINE INTERFACE In this style of interface you have to type every command as a short word and then press the Enter key. Every command has a special code or word that must be remembered, as there are no visual clues (such as icon to click) like a graphical user interface. For example, in many command line operating systems, typing the command CLS would instruct the computer to clear the contents of the current screen. Many Linux users choose to use this kind of interface instead of the graphical user interface. Before the introduction of the Microsoft Windows operating system, the operating system DOS was very popular and it only used a command line interface. Most command line interfaces have their own unique set of commands to perform common tasks such as navigation, formatting, creating, saving, copying and deleting files, and using searches and Help. 268 Version 2 TPC Janine Ratcliffe Figure 6: Screenshot of DOS – an example of a command line user interface 2010 Drives and directories In this style of interface it is essential to be able to navigate around the operating system. You need to know exactly where you are and how you can move from one device to another. All disk devices are usually referred to as a letter, for example: Drive letters A: floppy drive C: hard disk drive D: CD-ROM (usually) E: other drives such as USB disk, network drive, etc Within each of these drives, files are usually organised into structures called directories. You create directories to help keep files of a similar type together. Some operating systems, such as Windows, use the term ‘Folders’ instead of the terms ‘Directories’. In order to check what is contained within each of the directories, the command line interface provides a command to display files within the current directory. ls is the command used in the Linux command line structure, to list the contents of a directory. dir is the command used in DOS to list contents of a directory. Figure 7: Screenshot of DOS – example of listing the contents of a directory The command to move between directories, in most command line interfaces, is cd (which means change directory). cd can be used as: cd (takes you back to previous directory), or cd.. (takes you to one directory above where you are currently). Figure 8: Screenshot of DOS – example of changing to a directory called Westwood Formatting Formatting and naming a volume (a disk) can also be done within a command line interface. For example: format a is the command used to format a floppy disk in DOS to format a floppy disk where a: indicates the name of the drive for formatting. 269 Version 2 TPC Janine Ratcliffe Like a graphical user interface, a name can be created for the disk when formatting it, for example: 2010 format a:/v:mystuff is the command used to format a floppy disk in DOS, while also giving the volume label (or name) ‘mystuff’. Wildcards and searching Wildcards are useful symbols that can be used with many command line interface commands, to help you when you are unsure of the whole name of a file or you are looking for a group of files that have some characters in common. Wildcards are also useful when searching for information. Wildcard symbols include: * this represents a number of characters ? this represents one character. Some examples of how wildcards could be used include: dir d*.* displays all files that commence with the letter d (DOS command) dir *d.* displays all files that end with the letter d (DOS command). The Linux command line interface also includes a Find command that can be used to find files, and this can also be use in conjunction with wildcard symbols. For example: find/westwood –name ‘*happy*’ – this would display any file inside the westwood directory that contained the word happy (Linux command). Create, edit, copy and delete files Command line interfaces also contain commands that allow you to create, edit, save, copy and delete your files. Some examples are as follows. Linux commands Create and edit a file touch is the command to create a file. Example: touch stuff.txt would create a file called stuff.txt. There are many other ways to create files in Linux. Another way is to use a text editor called pico that would then allow you to edit the file. pico stuff.txt would allow to create and edit a file called stuff.txt. 270 Version 2 TPC Janine Ratcliffe 2010 Copy a file cp is the command used to copy files. Example: cp stuff.txt stuff2.txt would copy the file stuff.txt to stuff2.txt. Delete a file rm is the command used to delete files. Example: rm stuff.txt would delete the file stuff.txt. DOS commands Create and edit a file Like Linux, DOS also has a text editor that allows you to create and edit files. The command edit allows you to create and then change a specified file. Example: edit stuff.txt would create a file called stuff.txt. Copy a file copy is the DOS command used to copy files. Example: copy stuff.txt stuff2.txt would copy the file stuff.txt to stuff2.txt. Delete a file del is the command used to delete files. Example: del stuff.txt would delete the file stuff.txt. 271 Version 2 TPC Janine Ratcliffe Help 2010 If you are using a command line interface it is important that you know where any Help facilities are located. The Help facilities can give you a list of all available commands as well as an explanation about what each command is able to do. Linux Linux contains a few different ways of using Help. man is the command that displays the contents of the manual pages (Help) on a specific topic. man man will allow you to see all the topics that are available. man ls would give you information about using the ls command. help ls would also give you brief information about using the ls command. DOS DOS also contains a Help function. help is the command to display a list of commands and a brief overview of their purpose. help dir command will give a more detailed explanation about a command. SUMMARY Getting familiar with your computer operating system’s user interface is very important if you want to use your computer effectively. The interface, whether graphical or command line, allows you to navigate around the computer operating system, manage and search for files, use Help and perform tasks such as disk formatting. Check your progress Now you should try and do the Practice activities in this topic. If you’ve already tried them, have another go and see if you can improve your responses.

Copy the file to either a floppy disk or removable disk. c. Delete the file named PEPPERS (that will be on your desktop or hard drive). 275 Version 2 TPC Janine Ratcliffe 2010 Task 2B The reading here will help you to develop your knowledge and skills for performing basic customisation of a user interface. This will involve an understanding of: Changing colours and themes Changing screen resolution File managers Accessibility options Changing icons for user logon. PERFORM BASIC CUSTOMISATION OF A USER INTERFACE Customising the user interface 276 Changing colours and themes 277 Changing the colour quality 277 Changing themes 277 Changing screen resolution 278 File managers 279 Changing the appearance of files and folders 280 Sorting files and folders 282 Accessibility options 282 Help for people with a vision impairment 282 Help for people with a hearing impairment 283 Help for people who don’t want to use a mouse 284 Changing icons for user logon 284 Summary 285 Check your progress 285 CUSTOMISING THE USER INTERFACE A user interface allows you to communicate with the software on the computer. It is the part of the software program that displays various commands on the screen that you are able to choose from. Because the screens in a user interface will be used on a frequent basis, most user interfaces will give you the opportunity to customise various features. These include changing the colours used on the screen, the screen resolution, font size, and file management display options, as well as personalising a user account with your own icon. If you are using a computer that belongs to a large organisation, you may not be able to personalise any of the features mentioned above. Many workplaces restrict users from changing the appearance of their computers, so all computers will behave in a similar manner. This ensures that all computers are set up to prevent potential problems that may occur. 276 Version 2 TPC Janine Ratcliffe 2010 CHANGING COLOURS AND THEMES Most software using a graphical user interface will have the capability to allow you to change the colours and the themes of the screens. The Control Panel or Control Centre is usually the place in most graphical user operating systems where you are able to change these features. There are several items you can change in relation to colour and themes including: changing the colour quality changing the theme of the desktop. Changing the colour quality Most user interfaces will allow you to change the number of colours (or the colour quality) used to display screens. The type of monitor and video adapter (also known as a graphics card) your computer is using will also determine the amount of colours from which you can select. Using more colours will ensure that your screen images will appear sharp and precise. Using the most colours will be useful when you use software that utilises a lot of graphics, while a smaller range of colours can be an advantage if you want your software programs to work quickly. Figure 1: Screen shot of the Microsoft XP operating system which will enable you to change the range of colours Changing themes Rather than just changing an individual colour for a particular control, changing a theme means that a group of controls, including scroll bars, title bars, font styles, buttons, and desktop backgrounds will all be changed automatically to a colour-coordinated theme. Changing the theme alters the appearance of the entire desktop, allowing your computer to take on its own personality. Some people, for example, use themes that will reflect their favourite football team. There is also a theme within the Linux user interface that can make your desktop 277 Version 2 TPC Janine Ratcliffe 2010 appear and behave like the Microsoft Windows graphical user interface. Operating systems will often have a number of existing themes you can use; they may also allow you to create a theme of your own. Figure 2: Screen shots of the Microsoft XP Operating System – Display Properties screens which enable a user to change themes and colour schemes CHANGING SCREEN RESOLUTION The resolution of a computer screen refers to the amount of detail the screen is able to display. Like the options for changing the colours, the resolution options you have will depend on the kind of monitor you are using. Changing the screen resolution can usually be done within the graphical user interface’s Control Panel or Control Centre. Resolution is measured in units called pixels. Each pixel is the smallest unit that can be displayed on the screen. Resolution is defined by the number of horizontal pixels and by the number of vertical pixels (for example 1280 1024 pixels). Some common resolution settings include 800 600, 1280 720 and 1280 1024 pixels. Usually the higher the resolution means that the desktop will be larger with smaller images. Although everything will be smaller, it will also mean that you are able to see more items on your screen. Some users, however, may prefer a lower resolution. Many people with impaired eyesight will need to be able to see images in a large format. Although there will be a smaller desktop, all the images will be bigger using a lower resolution. 278 Version 2 TPC Janine Ratcliffe 2010 Figure 3: Screen shot of the Microsoft XP Operating System which will enable you to change the screen resolution FILE MANAGERS File managers are the areas within the operating system that allow you to perform ‘house keeping tasks’ with your existing files and folders. You can search, rename, delete, move and copy files and folders to different locations. Figure 4: Screen shot of the Microsoft XP operating system file manager which is called Windows Explorer 279 Version 2 TPC Janine Ratcliffe 2010 Within each of these file management tools, there are many ways that you are able to customise the display of folders and files to suit your needs. With a user a graphical user interface some of the ways that you may be able to change the ways files appear include: changing the appearance of files and folders sorting files and folders. Changing the appearance of files and folders Normally, files and folders will appear as small icons within a file manager, although there will be options for changing how lists of files or folders are displayed. Some of the popular types of views include: icons, list, details and thumbnails. Examples of view options in Windows Explorer Figure 5: Selecting the view preference in Windows Explorer – using the Windows XP operating system Icons Icons view will display each folder and file as a small picture. Figure 6: Windows Explorer Icon view List The List view of folders and files is similar to the Icons view. However, all files and folders are arranged vertically in columns, rather than across the screen. 280 Version 2 TPC Janine Ratcliffe 2010 Figure 7: Windows Explorer List view Details The Details view will display folders and filers in a similar format to List view. However, it also can provide more information about each file such as the size, whether it is a file or folder and the date it was last modified. Preferences may also allow you to choose additional information to display, such as date of creation and the owner of the files. Figure 8: Windows Explorer Details view Figure 9: Changing Details preferences in Windows Explorer Thumbnails The Thumbnails view is useful to display small previews of all the images. This view is useful image files, such as clip art or photographs, so that you can see the images that the files contain without having to open the files. 281 Version 2 TPC Janine Ratcliffe 2010 Figure 10: Windows Explorer Thumbnails view Sorting files and folders It may be useful to also sort your files and folders into a particular order. By default, files and folders are normally sorted into alphabetical order, with folders displayed before files. Some other useful ways the interface may be able to sort your files include: by size — sorts the files in order of file size by type — this option will group files of a particular application type, for example, sort word processing files together and spreadsheet files together by date — sorts the files according to the date and time each file was last modified. ACCESSIBILITY OPTIONS Some user interfaces include accessibility options to help people with a disability to customise the interface to suit their individual needs. The accessibility options are usually found within the Control Panel or Control Centre of a user interface. Some accessibility options we’ll look at here offer: help for people with a vision impairment help for people with a hearing impairment help for people who don’t want to use a mouse. Help for people with a vision impairment There can be several types of tools available to help a user with a vision impairment, including utilities which magnify the text, change the contrast colours of the screen or use sounds whenever particular keys are pressed. Examples of tools To give you examples, below is a description of tools to help people with a visual impairment available in the Microsoft Windows XP operating system. Magnifier is a display utility, provided by Microsoft Windows that makes the screen more readable for users who have impaired vision. Some of Magnifiers main functions include: 1 changing the level of magnification 282 Version 2 TPC Janine Ratcliffe 2 changing the size of the magnification window. 2010 High Contrast is a useful option for people with vision impairment. High contrast changes the colour scheme so that the screen becomes easier to view with the selected colours. By using a high contrast scheme, font sizes may also be increased to make reading the screen easier. Figure 11: Using High Contrast in Windows XP operating system Toggle Keys are also useful for people with a vision impairment. Toggle Keys enable the computer to output a sound whenever one of the following keys are pressed: CAPS LOCK, NUM LOCK or SCROLL LOCK. Help for people with a hearing impairment Your system should have utilities that can help a person with impaired hearing. Examples of tools Utilities such as ShowSounds and SoundSentry enable programs to display flashing titles or captions in the place of either speech or sounds. These tools are available in Microsoft Windows XP operating system. 283 Version 2 TPC Janine Ratcliffe 2010 Figure 12: Sound accessibility options in Windows XP operating system Help for people who don’t want to use a mouse Your system may also have a utility to enable the keyboard to move the pointer, instead of using the mouse to do this. This is useful for people who may have difficulties using a mouse, or don’t want to use a mouse, Example: MouseKeys In Windows XP operating system the MouseKeys utility allows you to set the numeric keyboard as an alternative to using the mouse. Figure 13: The MouseKeys option in Windows XP operating system CHANGING ICONS FOR USER LOGON User interfaces that utilise user accounts may have the potential to change icons that display in the Start Menu before a user logs in to their account. For example, in the recent versions of the Windows user interface, user account details can be 284 Version 2 TPC Janine Ratcliffe 2010 changed within the Control Panel. Once a user account has been created a new picture or icon can be chosen for the user. The picture can be either be chosen from the selected display or chosen from any existing images (for example a photo) that resides on the computer. Figure 14: The User Accounts option to display a unique icon for each user SUMMARY Customising a user interface can be done in many ways and is useful for a variety of reasons. Changing settings such as screen resolution, colours and themes, the way files and folders display, accessibility options and user login icons are just some of the ways a user interface can be personalised. As well as catering to individual tastes, customising a user interface can be extremely important for people with either a hearing, vision or mobility impairment. Check your progress Now you should try and do the Practice activities in this topic. If you’ve already tried them, have another go and see if you can improve your responses. When you feel ready, try the ‘Check your understanding’ activity in the Preview section of this topic. This will help you decide if you’re ready for assessment. 285 Version 2 TPC Janine Ratcliffe 2010 Questions The best way to display photo files when using a File Manager is to display the list of files as: Icons Details List Thumbnails Setting a computer’s screen to a low resolution will: Make any images appear larger Make any images appear smaller Not change image size None of the above. The purpose of accessibility options is to: Allow the computer user more access to files and folders Allow the computer user access to change colours and themes Allow the user interface to be customise for each computer user Allow the user interface to be customised for people with a disability 286 Version 2 TPC Janine Ratcliffe 2010 Activity 1 Which view option is used to display the files in the above folder window? Is there any additional information included with the file display? Activity 2 Using your own operating system, use the Help facility to find out some accessibility options that could be changed for someone with a vision impairment. Explain how the accessibility options would help someone with a vision impairment. Activity 3 287 Version 2 TPC Janine Ratcliffe 2010 Look at the dialog box above. The colour scheme of the windows has been changed to ‘rose’. List four more parts of the user interface for which you can customise the colour. 288 Version 2 TPC Janine Ratcliffe 2010 Task 3 The reading here will help you to develop your knowledge and skills for installing, upgrading and uninstalling application software in a stand-alone environment. This will involve an understanding of: The difference between system software and application software Types of application software Factors to consider when choosing software Processes for performing an installation, upgrade or uninstall of application software. INSTALL, UPGRADE AND UNINSTALL APPLICATION SOFTWARE IN A STAND-ALONE ENVIRONMENT What are the types of software? What is an operating system? Application software 289 290 290 Accounting 291 Database software 291 Desktop publishing 291 Educational software 291 Electronic mail software 292 Games 292 Internet browsers 292 Spreadsheets 292 Word processors 292 Integrated packages 292 Factors to consider when choosing software 293 Choosing the type of software you need 293 Considering the version of the software 293 Compatibility of the software 294 Single user and multi-user software 294 Installing, upgrading and uninstalling application software 294 Installing software 294 Upgrading application software 295 Uninstalling application software 297 Summary 297 Check your progress 298 WHAT ARE THE TYPES OF SOFTWARE? A software application (or program) is a set of instructions that tells the computer how to do things. Anything that you can touch on the computer (such 289 Version 2 TPC Janine Ratcliffe 2010 as the mouse, monitor or internal components including the CD drive and hard disk) is known as hardware, whereas everything that you cannot see or touch is known as software. There are two main kinds of software: system software and application software. System software includes the operating system which controls the basic functions of a computer (such as managing files and talking to the hardware devices). Application software, however, allows the user to complete specific tasks including creating a word processing document, producing a spreadsheet or playing a game. The hardware, system software and application software need to work together for a computer to operate. Without any system software, the computer hardware would not function and the application software would not be able to be used. If there wasn’t any application software there would be few tasks a computer would be able to accomplish. What is an operating system? The most important kind of system software is the operating system. Every computer needs an operating system in order to run the application software and control the hardware devices connected to it. Most computers are supplied with an operating system that has been pre-installed. Examples of popular operating systems are: 1 Microsoft Windows – the most well known operating system 2 Mac OS – designed specifically for Apple Macintosh computers 3 Linux – a freely distributed operating system. Some of the functions that an operating system may perform include: playing a part in starting up and shutting down the computer controlling the communications between other computers and the Internet managing the hardware devices (such as monitor display, mouse movement) organising files. A computer system consists of hardware and software components: APPLICATION SOFTWARE Once the computer’s operating system is functioning, application software can also be loaded onto the computer. Computer hardware Each piece of application software is designed to do a particular job such as mouse,performing monitor, disk drive creating a text document, mathematical calculations or organising and storing large amounts of information. The following list identifies some of the popular categories of application software: accounting database software Operating system desktop publishing software educational operating system electronic mail (email) software games 290 Version 2 Application software word processor, spreadsheet, game TPC internet browsers spreadsheets word processors integrated packages. Janine Ratcliffe 2010 Accounting There are many accounting computer software applications available that record and process accounting transactions such as: tracking income and expenses, performing taxation calculation and sometimes payroll functions. Depending on the needs of the user an accounting package may be purchased as third party software (packaged software) or may be developed within the company (customised software). Some popular accounting software programs include: Quicken by Intuit, Inc. MYOB. Database software Database software helps to store large amounts of information. Databases are organised in a logical order so that you can search for information very quickly and easily. Examples of databases include: Microsoft Access Paradox Filemaker dBase. Desktop publishing Desktop publishing software (which is also known as ‘page layout’ software) is used to combine text and graphics to produce, for example, professional quality newsletters, brochures or magazines. Many recent word processors also have desktop publishing features. Examples of desktop publishing packages include: QuarkXPress Adobe Indesign Microsoft Publisher. Educational software Educational software’s main purpose is to teach the user a particular skill. It can range from simple games that cater for pre-school children to programs such as typing tutors and foreign language tutors. 291 Version 2 TPC Janine Ratcliffe Electronic mail software 2010 Electronic mail software, or email software, enables you to create and send messages over the Internet or an Intranet. One of the most well-known email software programs available is Microsoft Outlook. Games Today there are thousands of games available for you to buy for your computer. Games can include arcade games, where a user needs to test their hand-eye co-ordination, strategy games or computer versions of traditional board games. Internet browsers An Internet (or web) browser enables you to view website pages. Today there are many web browsers that are available free, and some that are included with other software. Some popular web browsers available include: Microsoft Internet Explorer Netscape Navigator Mozilla Firefox. Spreadsheets A spreadsheet is an application program designed to manipulate numeric information. It is a rectangular grid that provides you with a way to productively and creatively use all kinds of mathematical formulas and calculations. Some popular uses of spreadsheets include: creating charts to represent your information, developing budgets or displaying profit/loss statements. Spreadsheet programs currently available include: Microsoft Excel Lotus 123. Word processors A word processor is an extremely popular application program that allows you to compose and edit letters, memos and reports. It is a powerful tool that allows a user to create documents by entering text, importing text or graphics, moving and copying text, formatting (including changing margins and fonts), and printing. Some popular word processing applications include: Microsoft Word Word Perfect. Integrated packages An integrated package is a collection of different software programs that are designed to work well together. Microsoft Office is a popular integrated package, which bundles together a word processor, a spreadsheet and several other small 292 Version 2 TPC Janine Ratcliffe 2010 applications such as a photo editor. There is usually some capability for each program to interact easily with another. For example, a spreadsheet might be able to be linked to a word processing document. FACTORS TO CONSIDER WHEN CHOOSING SOFTWARE When choosing software you need to consider a number of issues including: the type of software you need the version of the software you require compatibility of the software with the current operating system and the computer hardware whether you need single or multi-user software. Choosing the type of software you need Before choosing any software it is important to consider the purpose for the software. Do you need software to create text documents? (You may need a word processing application.) Do you need to perform mathematical calculations? (You may need a spreadsheet application.) Do you want to use software for recreation? (You may need a game.) Do you need to keep records of your accounts? (You may need accounting software.) Do you need software to help a child with their mathematics? (You may need educational software.) Many people will use only a few basic features of the application software they select. For instance, most people use a word processor to create simple letters or memos. If you will only be using software for these kinds of simple tasks then it may be unnecessary to buy software with extensive features. If, however, you need to use the software for complex tasks on a regular basis, a basic software application may not be adequate. Considering the version of the software Software companies regularly enhance their software and are constantly placing new versions of their system software, application software or integrated packages in the market. A version means a major change in a software program. A version is usually indicated by a number such as 1.0, 2.0, etc. The highest version number of a software program available means it is the newest, or most recent, version of the software. Software companies will also do minor changes to their software and thus also issue new releases. A release is indicated by a decimal number after the version number, for example 2.1, 2.2. Note that not all software companies follow this numbering system. Microsoft, for example, often uses years rather than numbers to indicate the latest versions of their software, for example Microsoft Office 2003 and Windows 2000. Depending on the computer hardware, the operating system and your personal requirements, you may or may not always have to install the latest version of software. Some older operating systems, for example, may not be compatible 293 Version 2 TPC Janine Ratcliffe 2010 with new versions of software. You must always check the system specifications and hardware requirements for the software application to confirm whether your hardware and operating system will be compatible with the version of software you intend to install. Compatibility of the software Compatibility refers to the ability of the software or hardware to work with other software or hardware effectively. Before choosing any application software it is important to determine whether the software will be compatible with the current operating system and the hardware, so you don’t buy software that will not work with the computer system. Compatibility can be determined in a few ways including: checking the software company’s website reading the specifications on software packaging or in a user manual. Ensuring that application software is compatible with the operating system is critical. Some software companies create different versions of their software so that there is a version available to run on different operating systems. For example, Microsoft has created two versions of its word processing package, Word, to work within a Windows (PC) and a Macintosh environment. Before you purchase any software application, make certain to read the specifications to find out whether the software will work under your operating system. If you purchase a word processing package that has been designed to work on a Windows operating system, it will not also be able to be used on a computer with a Linux or Macintosh operating system. It is also very important to check the hardware requirements for the software. It can be quite possible that very recent versions of software may not be able to run on an older computer. It is always better to exceed rather than meet the minimum hardware requirements. Some of the hardware requirements that will need to be met include amount of RAM (random access memory), type of processor and a certain amount of hard disk space. If a computer only just manages to meet the requirements, there is a good chance that the software will run very slowly. Single user and multi-user software When choosing software it could be designed to work for only one person at a time to use the software (a single user) or designed for many people to use the software at the same time (multi-user software). Many operating systems have been especially developed to allow people to network-selected computers — so that everyone will be able to work together and share items such as files and printers. Many database software programs are also designed for multiple users, so that all computer users using the database program can have access to the same information at the same time. INSTALLING, UPGRADING AND UNINSTALLING APPLICATION SOFTWARE Installing software Installing software is the process of transferring a software program onto the computer operating system so it is able to function. Generally, when installing software the following procedures will occur: 1 Files and folders that the software needs to use will be copied on to the computer’s hard disk. The operating system settings will be adjusted to ensure that the program works properly. 294 Version 2 TPC Janine Ratcliffe 2010 Performing an installation Depending on the operating system and the application that you want to install, the process of installing software will vary. Install means to prepare the computer to use the software for the first time. Application software which needs to be installed usually comes on a: CD, DVD, or floppy disk format and/or can be downloaded from the Internet in a file format. Sometimes a software program will automatically install after you insert the CD/DVD/floppy disk. However, for some programs you will have to manually start the install process. The operating system you are using will determine how you perform the installation. Some operating systems have utilities, to help you install new programs. With other operating systems you will have to use a file management tool to help you find the files you need to install. Figure 1: Screenshot of Windows XP – In the Control Panel there is a special utility to add new programs Most software installations will guide you through a series of steps, asking you questions regarding choices about the setup. If you are asked to choose between a ‘typical’ or ‘custom’ setup, and you are unsure, it is safer to choose ‘typical’ as this will install the program with default values. Installation tips Here are some tips to ensure a successful installation: If you need to find the file to open first, in order to start the installation process, it will often be called Setup or Install. Read any manuals or software guides (files usually named README) before installation, to check for any special steps that you may need to perform. Close any other programs currently running on the operating system. Many software installations will guide you through a series of steps, asking you questions regarding choices about setup. If you are asked to choose between a ‘typical’ or ‘custom’ setup, and you are unsure, it is safer to choose ‘typical’ as this will install the program with default values. Upgrading application software In order to take advantage of new features in a new version of the software that is released, you may find that you will be able to purchase an upgrade of the existing software program. When choosing an upgrade, rather than a new copy of 295 Version 2 TPC Janine Ratcliffe 2010 the software, you will still need to install the upgrade software; however there will be no need to delete the old version. When you install the upgrade software, it will update the old version of the software with any new functions or features. Note that you must have an older version of the software on your computer if you are installing an upgrade. 296 Version 2 TPC Janine Ratcliffe Uninstalling application software 2010 Many operating systems have utilities to help you uninstall your application software — an uninstall utility. You may discover that you don’t want to use a particular program anymore, or maybe you would like to get rid of programs that are either out dated, not suited to your needs or just taking up room on your hard disk. For example, in recent versions of Microsoft Windows, within the Control Panel, there is an option to Add or Remove Programs. You can simply choose the program you want to remove and click the Remove button. Figure 2: Screenshot of Microsoft XP system – Add or Remove Programs If your operating system does not have an uninstall utility, or perhaps the program that you need to uninstall is not displayed in the uninstall utility, you will have to remove the program manually. This means using a file management utility to find any folders or files that belong to the program and manually delete them. You will also have to delete any reference to the programs (for instance any shortcuts that have been set up). When using this method to uninstall programs, note that there could also be system files that are a part of the uninstalled program, so it will be very difficult to completely remove a program from the computer system. SUMMARY There are many types of application software available in the market, including software to create word processing documents, spreadsheets to perform mathematical calculations, web browser software to help you browse the Internet and integrated packages which contain a few different types of software programs. To ensure that you install the correct type of software you need to consider various options: What functions do you require from the software? 297 Version 2 TPC Janine Ratcliffe 2010 Will the software be compatible with the computer’s operating system and hardware? Which version of the software will be the most suitable? It is also important to recognise that software can also be upgraded and uninstalled too.

System utilities are programs that are designed to help you fix and enhance your current computer system. Many operating systems include a range of utility programs to perform common tasks such as checking disks, backing up information, restoring information and reorganising information. Many other system utilities are available as third party software – this means that you purchase and install these utilities separately from the operating system software. Third party system utilities are designed to perform specific functions that the current operating system either does not perform or performs at a lesser standard. 303 Version 2 TPC Janine Ratcliffe 2010 The types of system utilities we’ll look at in this reading will allow you to perform these basic tasks: disk scan disk defragment file back up file recovery get system information. WHAT IS A DISK SCAN? A disk scan is a useful utility to help identify and repair problems on a hard disk or floppy disk; it is provided with some operating systems. It can perform a thorough check of the disk’s surface to ensure that it is able to read and write information on all areas of the disk. If the disk scan utility finds a problem it will usually display a message and offer to fix the problem. There is a disk scan utility on recent versions of Microsoft Windows and Apple Macintosh operating systems, where if you turn off your computer without exiting the system, the Scan Disk utility will run automatically the next time you start your computer. There are also third party utilities that you are able to use that will perform similar and sometimes more thorough scans of the disk. WHAT IS DEFRAGMENT? To a computer, defragment means that all the files on the computer’s hard disk will be placed in a neat and tidy order. Gradually, as a computer hard disk has many files added, updated and deleted, the files can start to become fragmented. Fragmentation means that portions of the files are scattered all over the disk. A defragment will ensure that all files are reordered so that their parts are placed adjacent to one another. This will mean the computer can now read these files much more quickly. Depending on how many files need to be reorganised, a defragment can take hours. If you use your computer regularly you should try and do a defragment at least once a month. A good time to do a defragment may be overnight – when nobody will be using the computer. Often an operating system will include several system tools, including the defragment utility. If it is not included with the operating system, a defragment program can be purchased as an external software program (a third party utility). Figure 1: A diagram of a disk before and after a defragment. The picture on the left displays a disk with lines (representing data) that have been randomly placed on the disk. The picture on the right displays a disk after defragmentation — the lines (data) now appear in a consecutive order. 304 Version 2 TPC Janine Ratcliffe 2010 Figure 2: A screenshot of the Disk Defragmenter utility provided with the Microsoft Windows XP operating system BACKING UP Backing up means making a copy of your files, in case your computer hard disk fails and your original files become ‘corrupted’. Although for the majority of time the computer’s hard disk will not have any problems, occasionally a disk may fail unexpectedly. Some reasons why a hard disk may fail include: a sudden power failure computer virus damaging the hard disk damaged caused by knocking or moving the hard disk. Backups need to be done on a regular basis, so if there is a problem you will still have a recent copy of your files. It is also a good idea to keep backups in another location away from your computer. Make sure where you store your backup information is away from sunlight, dust and magnetic fields. Choosing a backup media It is important to choose the most appropriate kind of media to backup data to. When choosing media, be realistic; it is better to store backups using media that has a large capacity. Some suggestions include: Second hard disk: Some computers may have a second hard disk available that will allow a fast and easy method of backing up data. CD or DVD: Many computers have CD and DVD burners that will allow you to ‘burn’ data onto a writeable CD or DVD. 305 Version 2 TPC Janine Ratcliffe 2010 Zip disk: Zip disks are removable disks that hold between 100MB and 250MB of information. Tape drive: A medium that may be used by a business to backup business information. What should you backup? Backup anything that you have created yourself — including documents, digital photographs and video. All of these items will have no other way of being replaced if there are problems later on. If there is a problem, you can always reinstall the operating system and the application software using the original software CDs. How often should you backup? How often you backup will really depend on how often you use the computer and what is being stored on the computer. If, for example, your computer contains important business information that you are using everyday, it is a good idea to try to back up everyday. If, however, you only use your computer occasionally to play games or write the odd letter, a backup will probably only need to be done once a month. How to perform a backup Some operating systems include special backup utilities that make it easy for you to back up important files. If you don’t have a backup utility already installed you could install a third party program that is designed to do backups or manually copy and paste your files from the hard disk to your backup device. Backup programs allow you to easily select files that you want to back up, then they copy the files to the chosen backup device. A backup program may also compress the files before they are copied so you can fit more files onto the backup device. RECOVERY A recovery utility is used to undelete a file that has been accidentally deleted. Many operating systems now include special recovery utilities to help you restore files that have accidentally been removed. Microsoft Windows includes a Recycle Bin and Macintosh operating systems include Trash. Both of these utilities allow you a second chance to undelete any files on the hard disk. There is also a recovery utility in recent version of Microsoft Windows called System Restore. The System Restore utility keeps a regular log of all current settings so if, for example, a new installation of a program is causing problems System Restore will be able to reset all settings back to how they were before the installation. 306 Version 2 TPC Janine Ratcliffe 2010 Figure 3: A screenshot of the System Restore utility in Microsoft Windows XP operating system SYSTEM INFORMATION System information allows you to find out many things about your computer system. System information provides very detailed information about the hardware and software being used on the computer. Examples of the kind of information are: name and version of the operating system disk drives (including their size and free space available) hardware devices (such as a modems and keyboard) device drivers and their file names and locations Internet browser name and version application settings (such as default language and versions of software). This kind of information could be useful to a computer technician if you were experiencing major problems with your computer. It can be printed out or saved as a file when necessary. 307 Version 2 TPC Janine Ratcliffe 2010 Figure 4: System information displayed in Microsoft Windows XP operating system SUMMARY There are many operating system utilities and third party utilities available to help you fix and enhance your current computer system. Some of the more common utilities allow you to: use a diagnostic tool on a computer (disk scan and defragment) backup and recover files recognise system information.

This will involve an understanding of: Common input and output devices Device drivers Driver signing Installing a device driver Upgrading a device driver Removing a device driver. PERFORM BASIC SETUP AND SUPPORT OF A RANGE OF INPUT AND OUTPUT DEVICES What are I/O devices? 312 What is a driver? 313 What is driver signing? 313 Installing a device driver 314 Upgrading device drivers 316 Removing device drivers 316 Summary 317 Check your progress 317 WHAT ARE I/O DEVICES? Input (I) and output (O) devices are pieces of computer hardware that perform specific functions. Input devices allow information to be entered into the computer. The two main input devices a computer uses are a keyboard and a mouse. An output device displays information after it has finished being processed by the computer. Two main output devices include the monitor and the printer. Input and output devices are connected to the computer’s system unit. Each is connected using at least one cable. Some devices, such as a mouse, may also connect to the system unit using cordless technology. This means the cable is replaced with an electronic signal between the device and the system unit. Figure 1: Example of an input device – keyboard 312 Version 2 TPC Janine Ratcliffe 2010 Figure 2: Example of an output device – printer WHAT IS A DRIVER? A driver is a small software program designed to control an input or output hardware device. Every device needs a driver in order to interact properly with the operating system. Drivers provide the instructions for the operating system to understand how the device works. There are drivers that are used to control devices such as the mouse, CD-ROM drive and printer. Each time you add or change a device you may need to include a driver. Many drivers, such as the driver for the keyboard, are automatically contained within the operating system. These devices are known as ‘plug and play’. For other devices, such as a printer, you may need to load a new driver when you connect the device to your computer. When you buy a new input or output device to use with your computer, the device usually comes with either a CD-ROM or floppy disk which contains the driver software. Although some operating systems may already have a list of available drivers for you to use, chances are that not all the available drivers are up-to-date. It is better to use the driver that you have received from the device manufacturer. What is driver signing? In recent versions of the Windows operating system, Microsoft has introduced a new standard of driver which incorporates a procedure called driver signing. Driver signing is a guarantee to the user that the driver has been tested by Windows for compatibility. 313 Version 2 TPC Janine Ratcliffe 2010 Figure 3: Screenshot of Windows XP – the green tick indicates a signed driver Installing a device driver The device that is to be installed and the operating system that you are currently using will determine how you will install a device driver. Two possible ways a device driver may be installed are to: install manually install the driver. Install using the driver disk from the manufacturer After you have plugged your new device into the computer’s system unit, many operating systems will automatically detect that a new device has been installed. After recognising that there is a new device, the operating system will prompt you to install a driver. It is at this point that you can either choose from a list of the operating system’s list of devices or choose the driver disk provided by the manufacturer. Sometimes a manufacturer’s driver disk may also self load. Once you have inserted the disk, a program will run automatically. It may ask you a couple of questions, then it installs the driver for you. Manually installing the driver Some operating systems and drivers do not load in an automatic manner. Sometimes you may need to manually install a driver. Many graphical user 314 Version 2 TPC Janine Ratcliffe 2010 interfaces include a function that allows you to manage your device drivers. It is here that you can install a new driver. Figure 4: Screenshot of Microsoft XP Device Manager – this will allow you to add, upgrade and delete I/O devices and their drivers In a command line user interface, there may be a specific file (such as CONFIG.SYS) that contains the names of all device drivers. The below example displays the instruction to include a CD-ROM device driver within the DOS operating system: DEVICE = C:\HXCD-ROM\CDROM.SYS It is important that you read any instructions from the manufacturer of the device before trying to change these types of files. Testing a device driver Once you have installed a driver it is important that you test the device to ensure that it is working correctly. Try testing all different functions of the device to check that it will work correctly in all circumstances. Examples could include: Mouse Make sure that you can perform basic functions such as click, double-click, and drag. Make sure that you can configure the mouse for both a left and right-handed user. Monitor Ensure that you can change the resolution of the screen. 315 Version 2 TPC Janine Ratcliffe Ensure that you can change the available colours. 2010 UPGRADING DEVICE DRIVERS Sometimes it may be necessary to update some of your device drivers. This could be due to any of these reasons: you install a new version or different operating system you need to fix problems that may currently exist with an old version of the driver or hardware you want to improve the reliability of the hardware device. In order to upgrade an existing device driver you will have to find a new driver. The Internet provides the easiest way of searching for a driver. Steps to follow include those listed below. 1 Ensure that you know the manufacturer and model of the device driver you are trying to find. 2 Use a search engine to: – – find the manufacturer’s website — this website should include a driver’s page that allows you to download any drivers, or find a device driver website — search by entering the manufacturer’s name, model and word ‘driver’ to find any specialised driver websites. 3 Download any relevant drivers to your own computer. Make sure that the driver that you download has been designed for the same device model and is compatible for your operating system. Don’t be tempted into downloading a driver that may be for a slightly different model of device or for a different version of your operating system – it is unlikely that will work properly on your computer. 4 Install the upgraded driver. The upgraded driver should be able to be installed in a similar manner to installing a new driver. Some operating systems also have a facility that allows you to upgrade your driver automatically over the Internet. 5 Test the device and driver. Like when you install a new driver, an upgraded driver should also be tested to ensure that the device correctly functions in all circumstances. REMOVING DEVICE DRIVERS If you remove a current hardware device or upgrade drivers, it may be necessary to remove an old version of a driver. It is very easy to accidentally remove the wrong driver, so extreme caution needs to be taken before you proceed with removal. Once you have removed a driver, the change you have made will be permanent and it will be very difficult to restore the system. Some powerful operating systems (such as Windows XP) provide functions that will allow you to uninstall a driver and also Roll back driver. The Uninstall Driver function will delete any reference to the driver on the current computer system. This is a better option than trying to manually remove the driver yourself. The Roll back function will allow you to go back to using the driver that was being used previously. This is a great tool if you have accidentally installed an incorrect driver as it can easily return you to the old driver version. If you are using an operating system with a command line interface, removing a driver will need to be done manually. Before deleting a driver ensure that you have read any manuals that came with the driver to make certain you are 316 Version 2 TPC Janine Ratcliffe 2010 deleting the correct file. An example of a command to delete a driver using the DOS operating system is: DEL CDROM.SYS SUMMARY Device drivers are essential programs that allow all your input and output devices to communicate with the operating system. Without a correct driver, a device such as a keyboard, mouse, printer or monitor would not be able to function properly. Most devices include a driver disk that you can use to install the device. Sometimes, however, it will be necessary to go to the Internet to upgrade the current device driver. At a later time you may not need to use the device anymore, so you may have to remove the driver.

This requires evidence of your ability to apply techniques learned to the application of producing the work, eg use of hardware, positive participation in the learning process and practical tasks not requiring hardcopy output. OCCUPATIONAL HEALTH AND SAFETY The laws protecting the Health and Safety of people at work apply to students who attend TAFE Colleges, either part time or full time. These laws emphasise the need to take reasonable steps to eliminate or control risk at work (this includes a TAFE College). TAFE NSW has the responsibility for the control, and where possible, the elimination of health and safety risk at the college. You are encouraged to help in eliminating hazards by reporting to your teacher or other College staff, anything that you think may be a risk to you or other people. The OHS Act 2000 and OHS Regulation 2001 require that teachers and students take reasonable steps to control and monitor risk in the classroom, workshop or workplace. Examples of risks may include: · optical fibres · copper cable · electrical hazards · ergonomics. Your teacher will encourage you to assist in hazard identification and elimination, and to devise control measures for any risks to yourself and other people that may arise during practical exercises.
