COMPUTER SOFTWARE

Computer software Computer software is a program that makes the computer system work. It controls and monitors the working of a computer system. The computer will not work without software. Software also call programs are the instructions that tell the computer what to do and how to do it. The two main categories of software are system software and application software. The system software also called the operating system (OS) actually runs the computer. This software controls all the operations of the computer and its devices. All computers use system software and without the system software the application software will not work. The most common OS on a PC is the Windows operating system and for the Mac computer it would be the Mac operating system.

There are three types of software

  1. System software/Operating system

  2. Programming language

  3. Application software.

A working computer needs both the hardware and the software to function. Hardware + Software = A working computer system. A computer is a machine. It cannot think, count, calculate or draw all by itself. It must be told what to do. When we give computer instructions in a program, it follows the program

   The Computer appreciation and gives us the result or output. When the instructions in a program are right, the computer gives the right output. When, the  instructions are wrong, the computer gives the wrong output.

There are three types of software. These are the system software, programming languages and application software.

 System software

System software is a program that makes the computer system work. It controls and monitors the working of a computer system. It is also called the operating system.

Examples of system software are:

  1. a) Disk Operating System (DOS)

  2. b) Windows 2000 or Window NT

  3. c) UNIX

DOS and Windows 2000 are used in  microcomputers while UNIX is used in Main frame computers.

OPERATING SYSTEM

Operating System (OS) is one of the core software programs that runs on the hardware and makes it usable for the user to interact with the hardware so that they can send commands (input) and receive results (output). It provides a consistent environment for other software to execute commands. So we can say that the OS acts at the center through which the system hardware, other softwares, and the user communicate. The following figure shows the basic working of the operating system and how it utilizes different hardware or resources.

M.S DOS

 

Microsoft Disk Operating System, MS-DOS is a non-graphical command line operating system derived from 86-DOS that was created for IBM compatible computers. MS-DOS originally written by Tim Paterson and introduced by Microsoft in August 1981 and was last updated in 1994 when MS-DOS 6.22 was released. MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line instead of a GUI like Windows.

Windows OS, computer operating system (OS) developed by Microsoft Corporation to run personal computers (PCs). Featuring the first graphical user interface (GUI) for IBM-compatible PCs, the Windows OS soon dominated the PC market. Approximately 90 percent of PCs run some version of Windows.

LINUX OPERATING SYSTEM

Linux is a Unix-like, open source and community-developed operating system for computers, servers, mainframes, mobile devices and embedded devices. It is supported on almost every major computer platform including x86, ARM and SPARC, making it one of the most widely supported operating systems.

UNIX OPERATING SYSTEM

 

UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.

Activities

  1. Your teacher will take you on a visit to offices where computers are used. The offices you will visit include a school, a government office, a hospital, a business centre and a bank.

  2. In each of these offices, ask the computer users the various software they use and what each software does.

  3. List the software in each office as a system software, a programming language or application software.

  4. Your teacher will also show you all the software on the computers in your school computer room.

Utility Software

Utility software, often referred as utility is a system software that is designed to help analyze, configure, optimize or maintain a computer and enhance the computer’s performance. It is a program that performs a specific task, which is usually related to managing the system resources. Utilities are sometimes also installed as memory-resident programs.

Utility software usually focuses on how the computer infrastructure that includes computer hardware, application software, operating system and data storage programs operates. These utilities could range from the small and simple to the large and complex that can perform either a single task or a multiple tasks. Some of the functions performed by these utilities are data compression, disk defragmentation, data recovery, management of computer resources and files, system diagnosis, virus detection, and many more.

Examples of Utility Program

Some of the examples of the utility programs (Utilities) include: Disk defragmenters, System Profilers, Network Managers, Application Launchers, Antivirus software, Backup software, Disk repair, Disk Cleaners, Registry Cleaners, Disk Space analyzer, file manager, File Compression, Data Security and many more. In addition, operating systems contains a number of utilities for managing disk drives, printers, and other devices.

Advantages of utility software

Utility software has been designed specifically to help in management and tuning of operating system, computer hardware and application software of a system.

  • It performs a specific and useful function to maintain and increase the efficiency of a computer system

  • Aids in keeping the computer free from unwanted software threats such as viruses or spyware

  • Adds functionality that allow the user to customize your desktop and user interface

  • Manages computer memory and enhances performance

In general, these programs assist the user to make and run their computer better. They are also used for password protection, memory management, virus protection, and file compression in order to manage all the computer functions, resources and files efficiently.

Differences between applications and utilities

Utilities differ from applications mostly in terms of size, complexity, usability and their function. Most importantly utilities are more technical and are used by the people those with an advanced level of computer knowledge. In contrast, application software is simple and can be used by any user with no or less technical knowledge.

For example spreadsheet programs, word processors, and database applications are all referred as applications as they are large programs and perform a variety of functions that are not directly related to managing computer resources.

Evaluation:-

  1. Mention examples of utilities software

  2. List 3 advantages of utility software

  3. Differentiate between applications and software

 Application Software

– Word processing software

– Spread sheet

– Communication software

E.g (Explorer, outlook)

Application software

Application software is a program or group of programs designed for end users. Word processors, spreadsheets, database and drawing tools are written to perform special jobs. They are therefore called application software. Children often make use of word processors and drawing tools.

 

Microsoft Word is an example of an application software. We use it to type letters.

CorelDraw is also an example of an application software. It is used in drawing.

 

 

 

 

 

Communication software is used to provide remote access to systems and exchange files and messages in text, audio and/or video formats between different computers or users.

Spreadsheet

A spreadsheet is a computer application for organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets.
