Dear friends, Computer software is one of the most important topic in Computer Awareness. Questions related to system software, application software, software types, open source software, closed source software, freeware, shareware, word processing software, spreadsheet software, presentation software, graphics software, and the Open Source Initiative are frequently asked in SSC, JKSSB, Banking, Railway, Defence, Police, State PSC, and other competitive examinations.
In this article, Exam Waves Coaching Academy explains all important software concepts in very simple language, along with important facts and exam-oriented points.
What is computer software?
Computer software is a collection of programs and instructions that tells the computer what to do and how to do it.
Software helps the computer perform different tasks such as typing documents, calculating numbers, creating presentations, designing graphics, browsing the internet, and managing hardware devices.
Simple definition
Software = A set of programs that controls the working of a computer.
Examples of software include:
- Windows
- Linux
- MS Word
- MS Excel
- MS PowerPoint
Difference between hardware and software
A computer system consists of hardware and software.
- Hardware is the physical part of the computer.
- Software is the set of programs that runs on the hardware.
| Hardware | Software |
|---|---|
| Physical components | Programs and instructions |
| Can be touched | Cannot be touched |
| Examples: Keyboard, Mouse, Monitor | Examples: Windows, MS Word, Excel |
Both hardware and software are necessary for the proper functioning of a computer.
Types of computer software
Software is mainly divided into two types:
- System Software
- Application Software
This is one of the most important questions asked in competitive examinations.
