GENERAL PURPOSE PACKAGES
Presentation/Multimedia Packages
•
•
•
Multimedia documents combine text, graphics, sound, animation and
even video clips.
Multimedia authoring packages and presentation packages are both used
to set up slideshows to present information using all of these types of data.
Most packages provide you with a series of templates to choose from and
many will provide you with a wizard to help you set up a presentation.
Assembling the elements of a presentation
Before you start to assemble your pages you need to gather all the materials you
are going to use, for example the sound files, the graphics and the video clips,
and store them in folders.
Once you have your sound
files, graphics, videos and
animations stored in folders
you can begin to put the
presentation together. This
involves placing the
graphics and text where
you want them, attaching
sound files and inserting
video clips and animations.
This page has a
background graphic of
the Glasgow Science
Centre tower and text boxes are being placed carefully in the foreground.

GENERAL PURPOSE PACKAGES
Let us look at how the different elements of a presentation are put together.
Inserting text and graphics
There are two main ways of entering text:
•
using the keyboard
•
cutting and pasting from other documents.
There are a couple of standard ways of adding graphics:
•
from clip art files held on hard disk, CD or websites.
•
from folders of graphics that you have collected and stored on your hard disk.
Adding audio
You can attach an audio file to one or more slides in a presentation and, in
some packages, to an object on the slide. This is usually a simple matter of
pointing at the location of the audio file to link it to the slide or object. In this
example an audio file is being attached to the graphic object.

Adding video
Video clips are an integral part of a good
multimedia presentation.
Linking a
video clip
to a presentation document is usually
a straightforward matter of opening
the folder, pointing at the file and
clicking the mouse.
Some applications have templates of
pages/slides with control buttons like
play, forward and reverse already in
place. These are ready to have video
clips linked to them.
Capturing audio
You can capture audio for your presentation by:
•
•
•
•
recording a track from a CD
playing a musical instrument,
such as a MIDI keyboard,
directly into your computer
downloading a sound file
from the internet
recording sounds directly
using a microphone and a
recording feature like this one.
Your system really needs to have a good-quality sound card to enable you to
capture good-quality sounds. To find out more about sound cards see the
Computer Systems support notes.
Capturing images
If you want to capture your own images to put into your presentation you can
use these technologies that are explained in detail in other parts of the
support notes.

GENERAL PURPOSE PACKAGES
You can also use a
search engine on the
internet such as Google
to locate graphics.
Using hyperlinks to link slides
Linear linkage of slides
Once you have made up your slides you need to begin to link them up.
Some packages automatically link your slides to follow one after another. With
other packages you have to set up the links yourself. This graphic shows a set
of slides linked to follow one after the other.
STANDARD GR ADE COMPUTING STUDIES

GENERAL PURPOSE PACKAGES
When you are organising the slides in your presentation you can use
hyperlinks to give the user alternative ways through the presentation.
Hyperlinks link pages together and, by clicking on them, the user can jump to
a new page.
You can give the user a menu of hyperlinks and let them choose what they
want to look at.
These hyperlinks give the user a choice of revision questions to answer.
Hyperlinks can be attached to graphics, for example buttons or arrows.
Clicking on the buttons/arrows lets users move forward or backward or
even jump to pages they are
interested in.
The hyperlink attached to this button
will take you to some credit topics.
The hyperlink attached to this
arrow moves the user forward to the
next slide.

Creating a Web Page
Using a wizard or a template
This is a good way to
get your web pages
started. A wizard will
step you through the
process and templates
like these ones have page
structures already set up.
All you have to do is
select the one you need.
Adding text, graphics, sound and video clips
You can enter text into your web page by:
•
•
•
using the keyboard
cutting and pasting from another document
inserting a text file.
Adding graphics, sound and video clips to your web pages makes them truly
multimedia documents and makes them attractive. Adding these to your web
page is usually a simple
process of browsing
through your folders/
directories and clicking
on the graphic or video
clip you want inserted.
Here you can see a sound
file being attached to a
web page.

Using hyperlinks
You found out about using hyperlinks when you looked at multimedia and
presentation software. Hyperlinks are used on web pages to link pages
together and to help users find their way around your web pages.
Helping users find their way around your website
When you are linking your web pages using hyperlinks you should try to help
the users who are going to visit your site by setting up your hyperlinks so that
they have different paths through the site.
Graphic hyperlink
Text hyperlinks
This page offers the user text links, a graphics link as well as, in the main
menu on the left, links back to the ‘Welcome’ page and other courses.

Adding a hotspot
A hotspot is an invisible area on a page to which you attach an action of some
sort. When a user makes the pointer hover over the hotspot, or clicks on it,
an event takes place, for example it jumps to a new page, starts playing a
sound file or activates an animation or a video.
Using hotspots makes your page interactive and lets the user choose where to go
and what to find out. For example you could place hotspots on these graphics and
link them to text pages that explained what was going on in each one.
When the user clicks on the hotspot
that is marked by a circle, this text
box appears.
This is a sensor that
enables the robot arm
to identify objects
Here you see a robot arm on a
space station. Its reaction
time will have to be instant.
For further information on
Real Time Processing jump to
the systems section.
Here the hotspot, marked by a circle, is over a robot
arm that is attached to the space station.
This is one of the solar
panels that provide the
space station with energy.
The same graphic can have several hotspots attached
to it. Here the user has activated a hotspot that has
been placed over a solar panel on the space station.
Adding tables
Tables in web pages are
used to help you organise
the materials on your page.
They are an excellent way of
keeping text and graphics together.
Here you can see a table with
one row and two columns being
used to hold text and a graphic.
Here is a picture of
the Glasgow Science
Centre tower. It has
sensors that detect
wind speed and
direction. The data is
fed back to a
controlling computer
system that changes
the direction in
which the tower is
pointed.

What is an Expert System?
An expert system is a package that holds a body of knowledge and a set of
rules on a subject that has been gained from human experts.
An expert system helps the user make decisions by asking questions and then,
based on the user’s answers and the knowledge that it holds, offering advice. It
can even explain to the user how it arrived at its conclusions.
What is the purpose of expert systems?
Expert systems are designed to help people make decisions by making the
knowledge of a human expert available to them in a software package.
Expert systems are used to help people make decisions in a whole range
of situations.
•
•
•
•
•
In the financial world they are used by people to make decisions about
investments, risks, and complex projects.
In hospitals expert systems can help doctors diagnose illnesses and
suggest treatments.
In the oil industry they are used in exploration for oil fields.
In industry expert systems are used to help maintain and repair equipment.
In factories they are used to help manage complex production processes.
Expert systems have the following advantages.
•
•
•
•
•
They make expert knowledge available through a computer system.
They combine the knowledge of lots of experts.
They support people when they have important and complex decisions
to make.
People in remote places, for example doctors in remote hospitals, can
have expert help and advice on hand in the shape of the expert system.
People can learn using expert systems by asking questions, reading the
answers and asking the system to give feedback on the reasons for the
answers given.

General Purpose Packages in
the Workplace
Jobs
How does the use of GPP in the workplace affect people?
Loss of jobs?
Some jobs might be lost but for most people the introduction of new systems
and packages means that their jobs change to fit in with the computer systems.
How does it change people’s jobs?
People have to work with GPP and this means they have to:
•
learn new such as like word processing, using spreadsheets, constructing
web pages.
Need for training
When a new package is introduced staff members have to attend training
courses. These can be very expensive but there are advantages, such as:
•
once trained, staff can make full use of the packages
•
the business will run more efficiently and this should make the cost of
the training worthwhile.

No more paper?
Using computers to store all our data means that we can store data and
documents on hard disks, CDs even DVDs. Does this mean the end of paper?
Because we can store so much on CD and hard disk or even USB Flash
memory it does mean that there is less paper around, and less need for filing
cabinets to store the paper in.
But, so many people have access to printers that it is inevitable that we still
produce lots of printouts.
One big source of paper is the endless stream of junk mail that is churned out by
computer systems and posted to you, though nowadays a lot of it comes by e-mail.
A paperless world is still a long way off.
Exercise 22
1. What do people need to learn when new general purpose packages are
introduced to their workplace?
2. Training courses can be very expensive. Why are businesses prepared
to pay such a lot for training?
3. Is your printer rarely used or do you still need lots of printouts? List the
documents you need to print out.
Initial costs, replacement costs and
running costs
When you set up a computer system with all its hardware and packages you
have to remember that there are a lot of costs involved.
Initial costs
These involve paying for:
•
computer systems
•
application packages
•
training courses
•
installation of cabling and power sockets.
Replacement costs
Replacements are always needed because:
•
newer, more powerful computers are developed all the time
•
new software with advanced features is constantly coming on the market
•
new technologies, for example wireless computing, become available
•
hardware such as scanners, monitors and printers eventually wears out
and needs replaced.

The Law
Data Protection
Act 1998
The need for the Data Protection Act
Data held about people on computers and networks can be hacked into and
the data can be changed, copied or deleted. People’s privacy can be invaded.
To protect the data and people’s rights the Data Protection Act was passed by
Parliament to protect people’s privacy. There is so much private information
about people held on computer systems that it is possible for mistakes to be
made and for data to get lost. There are also lots of hackers (people who try to
get unauthorised access to data) who are constantly trying to access, copy,
change or delete private information.
When businesses or organisations keep information about people on computer
systems they need to make sure that:
•
data is backed up
A system of making regular backup copies is necessary. This makes sure
that if data is lost it can then be recovered from the backup copy.
•
data is protected
Anyone who holds data on people must try to protect it from hackers.
A common way of doing this is to use IDs and passwords. This is a good
system and does restrict access to people who are authorised to see,
search through and update data. Unfortunately, it does not stop all
hackers.
•
data is checked for accuracy
When data is being entered into a system or being updated people can
make mistakes with the result that the data is inaccurate. Unfortunately,
despite the fact that businesses and organisations carry out checks
mistakes still happen and inaccurate data does get stored on computer
systems.
So, if hackers can get through and mistakes can happen, there is a need to give
people the right to access their own data.

Everyone’s right under the law
The Data Protection Act gives everyone the right to see data that is held
about them on a computer system and to have it changed if it is wrong!
There are exceptions to the Act
If the data is held by the police, the security forces or the Inland Revenue
then access is denied.
The Data Protection Act was passed by Parliament in 1984 and updated in
1998. The important points you need to know about are as follows.
Data subject
Data subjects, the people who have data held about them, have the right to:
•
•
•
•
•
•
know if data is held about them on a computer and to have a copy of the data
know why the data is being processed and who is going to receive the data
inspect that data and to have it changed if they think it is inaccurate
ask for compensation if data is inaccurate or if an unauthorised person
has been given access to it
prevent processing of data likely to cause damage or distress
be sure that decisions made about them are not made only on the basis
of automatic computer processing.
A data subject can also apply to the courts to block the processing of data or
to correct, erase or destroy it.
Data controller
A Data controller is the person, business or organisation controlling the
collection, contents and use of personal data.
The data controller must:
•
•
•
register with the Data Protection Commissioner
apply for permission to keep personal data on computers
state what data they want to keep, what it will be used for and who has
access to it.
The data controller must keep to the following data protection principles. All
personal data should:
•
•
be processed only if the consent of the individual is given, if it is part of
a legal contract, if it is essential to a business transaction or the carrying
out of public duties
be held for the specified purposes described in the Register entry

‘This graphic is an example of a toolbar. It is made up of a series of
icons.’
The HCI is the part of the computer system that we humans use to
control, and communicate with, the computer system.
It is an HCI that is based on graphical displays such as icons, windows
and dialogue boxes.
It is a graphic that represents a file, a folder, a piece of hardware or a
software package.
Likely answers are: ‘printer’, ‘floppy disk drive’, ‘removable hard drive’,
‘CD-writer’, ‘scanner’, ‘digital camera’.
Windows, Icons, Menus, Pointers. (or Windows, Icons, Mouse, Pulldown-menus.)
Because it is so user friendly.
A template is the skeleton of a document with much of the format of the
document already in place, such as headings, colour, fonts, tables and
text boxes. An example is a template for an invitation card.
A wizard is a sort of tutorial that guides you through a complicated task. A
popular use of wizards in general purpose packages is to take you, step by
step, through the process of setting up a document or labelling a chart.
‘Online help’ is a collection of information about the features of your
software packages that is part of your package. You would use it to find
out how to perform a task, for example how to display the formulae in
a spreadsheet.
It means making changes to the HCI to fit
your personal taste.
Some likely answers are: ‘changing the size
and shape of your icons’, ‘changing the speed
of the pointer’, ‘changing the appearance of
the desktop: its colour, the screensaver being
used’, ‘changing the keyboard settings, such as
the cursor blink rate’.
Obvious shortcuts are Ctrl-P to print, Ctrl-S to
save, in fact any on an edit menu like this one:
Using keyboard shortcuts is a direct and quick
way to get tasks done. This is because you can
avoid using a series of menus, which slows you

•
They make it easy to transfer data between packages.
•
They have a common HCI that makes them easier to use.
This means that each of the programs in the integrated package have very

This depends on the packages available to you at home and in school.
• They enable us to complete our tasks quickly and efficiently.
• They help us keep data accurate and up-to-date.
• They make changing or adapting documents easy.
• Using these applications you can produce a whole range of different
types of documents that you can use to communicate ideas and
information to people.
• They help increase productivity.
Because the documents are stored electronically it is a simple matter to
delete data, insert data or add to data. The most likely examples are
word processing and graphics, but a document from any package will do.

A template is the skeleton of a document with much of the format of the
document already laid out.
It speeds up the production of documents. Because the structure is
already in place, all you have to do is call up the template and then fill
in the content.
This will vary from package to package. Here is some info on templates
from Word:
• A template determines the basic structure for a document and contains
document settings such as AutoText entries, fonts, key assignments,
macros, menus, page layout, special formatting, and styles.
This is a practical exercise that will depend on the wizards available to
you in your software. Your teacher will help you choose a couple of
wizards to use.
A wizard steps you through a complicated process that otherwise you
would find quite difficult.
You will use a simple key press such as Ctrl-H.
There are lots of things you can do to change the HCI: change the
appearance of the icons in your folders, alter the cursor speed, alter the
blinking of the cursor, change the colours of the desktop. Experiment
with these changes until you have the desktop that suits you. You may
find in some schools there are restrictions on the number and type of
changes to the HCI you can make. Check with your teacher.

• Integrated packages make it easy to move data from one application
to another.
• The different applications in an integrated package a have a common

without having to master a completely new set of menus and icons.
• They are cheaper than having to buy a series of individual packages.
Each application in the package will have fewer features than the
equivalent individual package.
This will depend on the software available to you.
In an integrated package all the applications, for example the wordprocessing package, the database, the spreadsheet will have similar icons
and menus.

The most common method is simply to highlight some data then copy
and paste it into whatever document you want, for example highlight
some cells in a spreadsheet, copy them then paste them into a wordprocessing document.
Integrated suites are collections of applications usually produced by the same
software company that have a common HCI and use standard file formats.
Each of the packages in the suite has a full set of features and so is a
much more powerful piece of software.
This is because each of the applications is a fully developed software
package in its own right and is much more powerful than the equivalent
part of an integrated package.
Using dynamic links between documents makes the process of updating
linked documents easier. All you have to do is change the data in the source

• The system then takes the data from the data file, inserts it into the
standard letter then sends it to the printer. It is usually then sent to the
printer straight away, though the user can choose to perform the
merge and send the merged document to the printer later.
Because he can automate the process of producing the letters. He can use
a database file to personalise 50 copies of a standard letter that is saved
on his hard disk.
This feature enables you to set up the structure of a document with its
main features such as headings, fonts, sizes, text boxes already in place.
Once you save this document as a template you can call it up at any time
and simply add content to produce a document. The fact that you can
create a template means that you can add to the templates that come
supplied with your package.
Text is scanned into the system and then the OCR software compares the
shapes of the text scanned in with those it holds in memory. When it gets
