Key Unit Competence
Understand the functions of operating system; install and use application and utility software.
1.1 Operating system (OS)
operating system is a large and powerful program that controls and manages computer hardware and application software. It is the most important computer program.
operating system software runs and manages all the operations of the computer. All electronic devices use operating systems to work, for example; laptop computers, tablet, desktop computers, smartphone, router, etc.
he operating system that runs a laptop or desktop computer is commonly called Desktop Operating System (DOS). this includes; Microsoft Windows(with versions like Windows 10 and Windows 8, MacOS(from Apple and is formerly OSX), Chrome OS (designed by Google) and Linux (e.g. Ubuntu, Fedora).
Mobile operating system runs on smartphones, PDAs, tablet PCs and other mobile devices. examples include Android (manufactured by Google Inc.) and iOS (manufactured by Apple) etc.
Server operating system or server OS is installed and runs on servers e.g. web servers examples of server OS are: Windows server, Linux, and FreeBsD (Free Berkeley software Distribution)
When the user runs an application, the program sends requests to the operating system and the operating system commands the hardware to work as required by the user. Most of the work done by the operating system is hidden from the user, meaning the user does not need all the details going on but just sees the results.
1. Booting: the operating system is responsible for completing booting process of the computer. Booting is starting or restarting the computer. Cold boot starts the computer that has been turned off completely whereas warm boot restarts the computer’s operating system.
2. The operating system provides an appropriate User interface. the interface enables the user to interact with the computer software and hardware. the user interface can be Command-line interface (CLI) or Graphical user interface (GUI). With CLI, the user interacts with OS by typing in commands at the command prompt to perform specific tasks. examples include Disk operating system (Dos) such as Ms.Dos (Microsoft Disk operating system).
With GUI, the user interacts with OS by using a mouse to access windows, icons and menus e.g. Microsoft Windows (8 or 10)
3. Operating system manages resource allocation to various programs. the operating system loads programs in computer’s primary memory, runs them and allocates them run-time, memory space, processor time, input/output devices and instructions to use.
4. Memory management: the OS organizes how the primary memory is used by different programs through partitioning. Partitioning is the dividing of the primary memory to run different programs in different partitions or sections of the hard disk. When the size of the primary memory or RAM is not enough, the OS borrows a space from the hard disk and adds it to the primary memory or RAM. this memory is called Virtual memory or Virtual RAM. It enables the OS to run programs which require more memory than available RAM in the system, but it is much slower.
5. Manages user’s files. the OS manipulates how files are created, stored and retrieved using file system. When you store a file on a disk, it is stored in pieces and when you open it, the OS organizes those pieces together and opens your file. OS also handles tasks related to cutting, copying and deleting files and folders.
Note: File system is a method used by the operating system to name, store and organise files on a disk. For example Windows uses NTFS (New Technology File System).MacOS operating system uses a file system called HFS Plus or HFS+. HFS is written as Hierarchical File System. Linux has many file systems such as Ext 2, Ext 3, Ext 4, XFS, etc.
6. Operating system controls input/output peripherals. the operating system manages reading from the input peripheral devices and writing to all peripheral devices. It controls access to all peripherals through small programs called device drivers. A device driver is a program that controls how a specific device works with specific operating system. examples are: Printer driver, network driver and graphics driver.
7. Operating system manages files: operating system supervises the creation, storage, updating and deletion of files to various storage devices e.g. hard disk, flash disk, etc.
8. Operating system manages backup storage (secondary storage or auxiliary storage). operating system locates and retrieves files needed by user from backup storage and monitors how they are used.
9. Operating system manages security and access rights of computer users. In this case, the operating system monitors the creation of passwords, user names or account names on a computer. It also keeps record of who accesses the computer, the activities done and the resources used. In managing system security, the operating system guarantees that resources are used only for programs and users with appropriate authorization.
10. Operating system handles errors as they happen. When the computer is used, without user intervention or knowledge. It can suggest to the user what to do to correct errors through error messages.
there are several different types of operating systems and choice of which operating system to use depends mainly on; cost of buying the OS, hardware requirements to run the OS and user experience. the OS comes with two important components i.e. the Shell (which provide interface between the user and the operating system itself) and the Kernel (which provide interface between hardware and applications). You can install OS using different options among which are; fresh installation (done on a new computer or if the existing OS is damaged and cannot work); multi-boot installation (done when you install two or more different copies of OS on different parts of hard disk) and upgrading (done when you replace old version of OS with a new copy of OS e.g. replacing windows 7 with windows 10).
1. explain briefly the meaning of ‘operating system’ in the computer system.
2. Identify the operating system(s) that is installed in your school computers.
3. Discuss any five functions performed by the operating system in a computer.
4. Give an example of operating system that can be installed on each of the following devices:
b) Laptop computer
5. With clear examples discuss the following terms in computer system:
a) File system
b) User interface
1.3 Types of license for software
there are two types of licenses for software:
.open source software
1.3.1 Open Source License (General Public License or GPL)
Open source software is a computer program in which the source code is available to the general public for use or modification from its original design and free of charge.
Open source license is a license that allows the software to be freely used, modified and shared. this software license is widely used for free and guarantees end-users the freedom to run, study, share and modify software.
1.3.2 Proprietary license
Proprietary software is owned by an individual or company that developed it. the source code is kept almost secret, so you cannot modify it.
his means that the software is under restrictive copyright and the source code is hidden from users. Anybody cannot copy or change proprietary software unless permission is sought from owners. Most software today is proprietary.
Proprietary license is a software license in which the software publisher/owner grants a license to use one or more copies of software, but the ownership of those copies remains with the software publisher. the user must pay for the license before permission is given to use the software.
1.4 Download software
Download software means the transfer/copy of a software through the Internet from the remote computer (server) to a local machine or computer.
Downloaded software installation files (executable files) are commonly used for program installations.
Using a browser installed on your computer, download Google Chrome installation file from Internet onto your computer.
Step 1: open your Browser on the computer.
Step 2:Use the search engine and type “download Google Chrome” installation file in the search book.
Step 3:Press enter key (Return key) on your keyboard. Doing this will start the search for the specified item. After a short time, the search results display. Scroll to find the best result.
Step 4:Click the search result you think is best for you. this will take you to the items page. now click “for Personal Computers” the result will be as shown in the picture below.
Step 5:Click the “Download Chrome” button.
Note: If you download chrome, it automatically installs itself and so you may not see the downloaded file, but an already working program
Step 6: open your downloaded file(s). Do this by clicking on the file’s name bar at the bottom of the browser or by navigating to the computer’s default download location, which is a folder called “Downloads”.
Note: By default, all downloaded software and files are kept in the folder called Downloads on your computer from where they are transferred to another location of user’s choice.
Some programs take long to download and to install and others strictly require Internet connection to complete installation.
Create a folder on your desktop using your first name and use it to save all the downloads.
Using installed browser, download the following software installation files.
a) Avast antivirus b) Mozilla Firefox
c) VLC media player d) Adobe reader
e) Chess game f) skype
1.5 Installation of software
the term Software Installation means, the process of copying installation files of a given program onto hard disk in a format that allows the computer to run the program. It means putting a computer program on a computer and ready for use.
You should always read the manufacturer’s installation manual to correctly install programs. this manual describes all the procedures and the necessary system requirements for successful installation.
System requirements for installing software
.Processor speed (the higher the speed the better)
. RAM size
.Hard disk space
e.g. to install Windows 10, the minimum requirements usually include:
Processor 1 Gigahertz (GHZ) or faster processor or SoC (system on Chip or integrated circuit known as a chip).
RAM 1 Gigabyte (GB) for 32–bit or 2GB for 64-bit
Hard disk space 16GB for 32-bit OS or 20GB for 64-bit OS
Graphics Card Direct X 9 or later with WDDM (Windows Display Driver Model) 1.0 driver
WDDM is a graphic driver architecture for video card drivers running Microsoft Windows.
1.5.1 Installation of Operating system
operating system is installed in a separate section of hard disk referred to as disk partition. the hard disk is usually divided into multiple sections and each section or partition can operate independently of the other. Dividing hard disk into partitions is called disk partitioning.
Before you partition a disk, save or backup important files onto another disk because disk partitioning erases all the data on the disk and prepares it for new data using a particular file system such as FAT (File Allocation table) or NTFS.
the hard disk is usually partitioned when installing operating system. to partition your hard disk, insert in the optical drive a bootable DVD containing a desired operating system e.g. Windows 8 or Windows 10.
Note: While installing the OS, determine the type of file system you should use. File system is a method used by Operating system to keep track of files stored on computer. File systems commonly used by operating systems include: FAT32 and NTFS.
Modern operating systems such as Windows 10 mainly use NTFS (New Technology File System). Consider the type of file system best supported by OS or application software you want to use.
Since an Operating system has to take control of all other programs you will use, it must be installed first before other programs.
Provided with Windows 10 installation DVD or flash disk containing Windows 10 installation files, perform a fresh installation of Windows 10 on your computer.
Step 1:Backup all your data on an external storage device such as a flash drive or external hard drive. this is because clean installation deletes everything on your computer’s hard drive.
Step 2: start your computer and then connect the bootable USB flash drive or insert the bootable Windows 10 DVD on the PC where you want to install Windows 10.
Step 3:Restart your PC, and then press any key to boot from the USB flash drive or the DVD. Press the key after seeing the message as shown below.
If you restart your PC and your current version of Windows starts, then open a boot menu or change the boot order in your computer’s BIOS or UEFI (Unified extensible Firmware Interface) settings so that your computer boots from the media.
Note: To open a boot menu or change the boot order, press a combination of keys (such as F2, F8, F9, F10, F12, Delete, or ESC) as soon as you turn on your PC. However, the key (s) you press depends on the manufacturer of your computer’s motherboard and it is usually displayed immediately the computer starts. Check it out.
once you get the boot menu, select the best boot order such as Optical disk drive then press enter key.
Step 4: on the first screen for Windows setup, select your language, time, keyboard preferences and then click on Next button on lower right.

Key Unit Competence
Generate a table of contents and use one document to have multiple copies for different recipients.
2.1 Table of Contents (TOC)
A table of Contents is a piece of information used by readers to quickly find or locate what they are looking for in a book, magazine or any piece of literature.
Creating Table of Contents
Follow the following steps carefully to create a table of Contents:
Step 1: start Ms Word and then create a new document in which you need to add table of Contents. You will save the document asb
now use Microsoft Word and type the following text as it appears; then you will use it to create table of Contents and Lists of tables and figures in activity 2.2 and 2.3.
Information and Communication Technology Syllabus
ICT syllabus in secondary schools contains a number of items of study. one of the interesting items in the syllabus is about software. When a teacher plans to have an ICT lesson from the Computer Laboratory, all learners smile (like a smiley face shown on the right) because they are going to use computers practically. there is some information about software as shown above:
Definition of computer software
Computer software is defined as a series of instructions that tell the computer hardware how to process data. Computer software is sometimes called computer program. It is divided into two main categories;
About three quarters of what learners study is application software. As shown in the figure above.
these are computer programs that control the operation of a computer and its hardware devices. system software act as an interface between the user, application software and computer hardware. Modern computers are complex machines having many running parts all of which need system software to keep running. systems software also provide general functionality for other programs to use, tools to speed up the computer, tools to develop new software and programs to keep the user safe from attacks.
System software is divided into:
.Operating system: For example, Windows 8, Windows 10, Linux and many others.
.Utility programs: For example, Antivirus, Disk defragmenter and others.
.Translator software: For example, Assembler, Interpreters and compilers.
.Programming languages: For example, machine code, Assembly and Java.
The table below summarizes system software
these are programs that help end-users to accomplish specific tasks using a computer. these programs define what a computer can be used for. Most application programs are available as packaged software that can be bought and installed on your computer. the common categories of application software include:
Word processing software
Word processing software is the key to learning other application programs. on the above is a 7-point star for Microsoft word.
Management of figures is best learnt from lower level with spreadsheets software. this knowledge is important in business calculations. We give Microsoft excel a six-point star as shown on the above.
It is important that learners can convey information to particular audience in an organized way using a computer program. We can now give Microsoft PowerPoint a 5-point star.
other applications are equally good and learning the first three (above) gives a learner a good foundation for understanding other professional applications as given faster.
- Graphics and Multimedia software.
- Computer Aided Design (CAD) software.
- Database Management systems.
- Desktop Publishing.
- Project Management.
- Geographic Information systems.
- education software.
- entertainment software and many others.
The table below summarizes Application software
Step 2:Apply Heading styles to the text that you want to include on the table of Contents (Ms Word will use these styles to build the TOC automatically).
Note: the objects you see in text were wrapped. to wrap them and appear like that, you have to do the following:
Procedure to apply heading stylesselect text you want to be included in Table of Contents In our activity select the heading “Information and Communication Technology Syllabus” and apply Heading1 style. Do this by selecting Heading1 style from the Styles group on the Home tab. Repeat action above for heading “Computer software”.Bold your title. Repeat the procedure on subsequent titles using heading 2 in styles group and bold command in the font group on the Home tab:the titles to apply heading 2 in the text are:
- Click shape (the drawing tools automatically display under Format tab).
- Click Wrap text in the Arrange group on the Format tab.
- In the Wrap text menu, select tight (you can also test other options to see how they work).
- Move the picture or shape to the right until all the text appears on the left of the shape.
- Release the mouse button. Justify your paragraph or block of text in case of need by clicking Justify button in paragraph on Home tab.
Apply heading 3 style to text headings below:
- Definition of computer software
- system software
- Application software
Repeat this step for every text heading you think should be in your TOC.At this stage insert page numbers. Align right page numbers in the footer using 1, 2, 3 number format.Step 3:Generate an automatic Table of Contents for the document at the beginning of your document.To create Table of contents, do the following below:Creating table of ContentsClick where you want to insert the table of contents (usually at the beginning of the document).Click References tab > Table of Contents, and then choose Automatic Table 1 style from the list (see picture 2.2).Note: If you use a Manual Table of Contents style, Word won’t use your headings to create a TOC and won’t update it automatically. If you opt for manual method, then everything has to be done manually.When created, you can format or customize your TOC by changing font, number of heading levels, etc. A TOC can also be created in any other location in your document but it is most suitable at the beginning of your document.the table of contents that results from activity 2.1 is shown in picture 2.3.Activity 2.2open My-toC file and perform the following activities:a) Insert a page break at the end of the document.b) type the heading ‘Computer Hardware’.c) Generate a list of computer hardware available in your computer laboratory on the following categories:

5.1 Charts (Graphs)
A chart is a graphical representation of numerical data. It is a sheet of information in form of a table, graph, diagram or object.
Charts enable users to see results of data in detail, interpret and predict current and future data in a much easier way.
5.1.1 Uses of charts
- Used to summarize numerical information.
- View relationships between different variables e.g. Price against sales volume.
- Detect trends overtime and make forecasts.
- search for patterns among a large amount of figures.
Note: In unit 3, we looked at how we create charts in MS Word and this means you already know something about charts. Like in MS Word, a chart is created almost the same way in MS Excel but the difference is in steps you take to create it.
5.1.2 Types of charts
there are several types of charts used to present data pictorially. the charts mainly include; column, bar pie, line and scatter graphs.
You are given the following data to enter in Microsoft excel. save the data as ‘ICt marks’. Use the data to create a column, bar, pie, line and scatter charts. (Follow steps for creating a chart in section 5.2).
1. Column chart:A column chart displays data as vertical bars. If the data in table 5.1 above is entered in spreadsheet and a column chart created for ICT marks, it may appear as shown in picture 5.1.
2. Bar chart: A bar chart represents data mainly as horizontal bars or objects.
When the data in table 5.1 is used in Ms excel to create a chart, a bar chart for ICT marks may appear as shown in picture 5.2.
Difference between column and bar charts
A bar chart represents data using horizontal objects but a column chart uses vertical objects.
Similarity between column and bar charts
Both bar and column charts represent data using bars or columns to compare items. the length of each bar or column is proportional to the data that it represents. this means that a bar or column corresponding to a value of 100 would be twice as long as one corresponding to value of 50.
3. Line chart (line graph)
A line chart is a graphic representation of data plotted using a series of lines.
If the data in table 5.1 is used to create a line chart, it would appear as shown in picture 5.3.
4. Pie chart
Pie chart is a circular chart sliced into sections; each section represents a percentage of the whole. Pie charts do not display horizontal and vertical axes as other charts.
If the data in table 5.1 is used to create a pie chart, it would appear as shown in picture 5.4.
