CURSOR When you open any word application, you will see a blinking vertical bar in the text area. This is called Cursor. The cursor indicates where the next character you type will appear. This position is called the Insertion Point. What therefore is a cursor? A Cursor is defined as a blinking vertical bar which indicates the insertion point in a text area or field. When you press a key on the keyboard, the character you typed will be placed at the insertion point and the cursor will move one step to the right. When the mouse pointer is moved to a text area it changes from the normal arrow to an insertion point(which looks like a capital I) Normal mouse pointer Cursor Insertion point BASIC TEXT FORMATTING FONT A font is a complete set of characters of a single size and style of a particular typeface.

Definition of Internet The internet is a worldwide interconnection of computer networks. Internet is popularly known as Net. A computer network is simply two or more computers connected together that allows the computers to communicate and share information. These days the internet connects millions of computers from schools, homes, industries, etc together. Resources used for internet connectivity You can connect your computer to the internet through an Internet Service Provider (ISP). B. Internet Service Provider (ISP) An ISP is an organization that provides access to the internet, usually for a monthly fee. The ISP connects your computer to their system which is already connected to the internet thereby allowing you to also have access to the internet. Examples of Internet Service Providers in Ghana are Ghana Telecom Network Computer System (NCS) U-Com Zip-Net Broadband Africa Online Internet Ghana Wireless Ghana iBurst Broadband4U NetSAT Ltd. C. WORLD WIDE WEB (WWW) The world wide web is an interconnected system of pages or documents containing texts, images, sounds and video that can be accessed through the internet. The pages or documents on the World Wide Web are linked together using hyperlinks. D. HYPERLINKS Hyperlinks are text or images on web pages which when clicked will send you to another web page. Every web page on the internet has a unique address called Web address or Uniform Resource Locater (URL). All web pages start with the ‘www’ prefix. Examples www.yahoo.com , www.google.com , www.Ghana.gov.gh , www.knust.edu.gh ,www.cosmosschools.com, www.opponglexis.wordpress.com , etc. Web browsers A Web browser is a software that displays web pages on the internet. Once you have an internet connection and a Web browser, you can start using the internet. Every operating system has at least one Web browser installed on it. Examples of web browsers include Microsoft Internet Explorer Mozilla Firefox Netscape Navigator Opera FEATURES OF WEB BROWSERS Although there are different types of web browsers, there are some common features that are common to most of them. Features of Microsoft Internet Explorer Web browser Print button Back button Forward button Refresh button Address bar Stop button Functions 1. Address bar: This is where you type in a web address of the web page you want to visit. 2. Forward button: forward button take you to the next opened web page. 3. Back button: This button takes you back to the previous opened web page 4. Stop button: Stop button when clicked stops loading a page. 5. Refresh button: Refresh button reloads the current page. 6.

Delete the existing address in the address bar. 3. Type in the address of the web page you want to view. 4. Press the Enter key on your keyboard. EXITING A WEB PAGE Exiting a Web Page To exit a web page, just click on the Close button on the Title bar of the Web browser. NETWORKING AND THE INTERNET INTORUCTION TO NETWORK Network A. Network Definition A network consists of two or more computers that are linked in order to share resources (such as printers and CD-ROMs), exchange files, and allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites or infrared light beams. B. Benefits of Computer Networks 1. File Sharing - Network file sharing between computers gives you more flexibility rather than using floppy drives or Zip drives. you can use the network to save copies of your important data on a different computer, examples share photos, music files and documents. 2. Sharing Devices. Sharing devices is another benefit in which a network exceeds stand-alone computers. For example laser printers, fax machines, modems, scanners and CD-ROM players, when these peripherals are added to a network, they can be shared by many users. 3. Sharing Internet Access. In computer network, students can access the internet simultaneously. 4. Speed. Using a network is faster way for sharing and transferring files. Without a network, files are shared by copying them to floppy disk. 5. Cost. Networkable versions of many popular software programs are available at considerable savings compared to buying individual licensed copies. Its allows easier upgrading of the program. 6. Security. Files and programs on a network are more secure as the users do not have to worry about illegal copying of programs. Passwords can be applied for specific directories to restrict access to unauthorized users. 7. Centralized Software Management. One of the greatest benefits of installing a school network is the fact that all of the software can be loaded on one computer (the server). This saves time and energy when installing updates and tracking files. 8. Electronic Mail. A network that provides the hardware necessary to install an e mail system. E-mail’s help in personal and professional communication for all school personnel as it enables the spread of general information to the entire school staff. Example, electronic mail on LAN (Local Area Network) enables students to communicate with teachers and peers at their own school when connected to the Internet, it enables users to communicate with others. 9. Flexible Access. School networks allow students to access their files from computers throughout the school. Some schools provide public access to students to begin an assignment in the computer lab and save then access the file when they are at a cyber cafe or home. B. Devices Needed in Computer Network. Hub A central device that provides a common connection point for nodes on a network. Network Interface Card A NIC (network interface card) is a piece of computer hardware designed to allow computers to communicate over a computer network. Router A device that forwards data packets along networks. A router is connected to at least, two networks, commonly two LANs or WANs or a LAN and its ISP’s network. Connector Short for Registered Jack-45, an eight-wire connector used commonly to connect computers onto a local-area network (LAN), especially Ethernets. RJ-45 connectors look similar to RJ-1 1 connectors used for connecting telephone equipment. Modem Short for modulator-demodulator. A modem is a device or program that enables a computer to transmit data over telephone or cable lines. Computer information are stored digitally, whereas information transmitted over telephone lines are transmitted in a form of analogue waves. A modem converts between these two forms. TYPES OF NETWORKS Three types of networks: •Local Area Network or LAN •Metropolitan Area Network or MAN •Wide Area Network or WAN A LAN covers a small region of space, typically a single building. A MAN is a collection of LANs with the same geographical area, for instance a city. A WAN can be a collection of LANs or MANs or the mix of two with a very large geographical area, for instance a country or even beyond the border. LOCAL AREA NETWORK (LAN) Local Area Network (LAN) is the smallest network compared to the other two networks. The simplest form of LAN is to connect two computers together. LAN is operated within a limited physical area, such as at home, school, a single building or several buildings. A network which consists of less than 500 interconnected devices across several buildings, is still recognised as a LAN. Inexpensive hardware used in LAN previously include twisted pair, coaxial cables and the higher end is fiber optic or wireless. However, coaxial cables are now being replaced by a higher speed cabling system such as CAT5 using RJ45 connectors. LAN is a very high speed network (from previously 10Mbps) to 100Mbps, which is faster than MAN and WAN. Local Area Network is a group of computers and network devices connected together, usually within the same building.
