What is Software
Software is a set of instructions that are given to a computer to perform a particular task. It tells a computer how to perform a specific task. The software can be used to create documents, play games, manage finances, and much more. It is an essential part of modern computing, allowing us to do more with our computers than ever before.
Types of Software
- System Software
- Application Software
System Software
System software is designed to perform the internal functions of a computer and control hardware components such as monitors, keyboards, and mice. It also provides an interface between hardware and application software, allowing them to communicate with each other. System software is essential for the smooth functioning of a computer, as it helps to manage and coordinate the various components of the system.
E.g.:- Windows, Linux, and Mac OS.
Types of System Software
- Operating System:– An operating system is a software program that manages the hardware and software resources of a computer. It acts as an intermediary between the user and the computer hardware, allowing the user to interact with the computer.
- Language Processor:- The language processor is a special translator system that is used for turning a program written in a high language into a machine code.
- Device Drivers:- A device driver is an essential software program that facilitates the communication between a specific hardware device and a computer. Without device drivers, a computer would be unable to function properly, as they are responsible for enabling the hardware to interact with the operating system.
- Firmware: Firmware is software that is embedded in hardware devices like printers, routers, and cameras. It provides low-level control over the device and allows it to perform its basic functions.
Functions of system software include
- Providing a Platform: System software provides a platform for other software to run on. It manages system resources like memory, disk space, and processing power and allows other software to access these resources.
- Controlling Hardware: System software controls the hardware devices on the computer. It communicates with devices like printers, scanners, and sound cards through device drivers and firmware.
- Maintaining System Health: Utility programs included in system software help maintain the health and performance of the computer. They perform tasks like disk cleanup, virus scanning, and system optimization.
Application Software
Application software is those software which are designed to perform a specific task. This software is specially designed to solve the problems of one particular field. We cannot use application software in different fields to solve different problems.
E.g.:- MS-Office, Chrome, and Outlook.
Types of Application Software
- Pre-written Application Software:- Pre-written application software is designed for the common needs of various business organizations or applications.
- Customized Application Software:- Customized application software is designed for a specific application of a specific environment.
The functions of application software include
- Performing Specific Tasks: Application software is designed to perform specific tasks or applications. Word processors are used for creating and editing documents, while spreadsheet software is used for managing data and performing calculations.
- Enhancing Creativity: Graphics and multimedia software allow users to create and edit visual and audio content, enhancing creativity and productivity.
- Improving Efficiency: Application software can improve efficiency by automating tasks and reducing the time it takes to perform certain functions.
Distinguish between virus and antivirus?
| Virus | Antivirus |
| Computer virus is a malicious program, which has the ability to replicate and execute itself. | An antivirus software is a computer program used to scan files. It detects, prevents, identifies and eliminates computer viruses and other malicious softwares. |
| It is destructive in nature. | It is preventive in nature. |
| It harms the computer system in different ways. | It protects the computer system from viruses and other malicious softwares. |
| Crypto Locker and SQL Slammer are the examples of virus | QuickHeal and e-Scan are the examples of antivirus |
