What is software? Why we need software? and Types of Software

In this article, we will discuss what is software? and why we need software?. we also discuss types of software.

What is Software?

Computers have become an integral part of our daily lives, and the software that runs on them is what makes this possible. Software is a set of instructions, data, or programs that tell a computer what to do and how to do it.

It is the collection of computer programs, that run on the computer and perform specific tasks. A computer program is a written instruction in files, which are written in some programing language. Any task performed by computer is possible because of software or computer programs.

The purpose of the software is to provide a way for users to interact with a computer and perform desired functions, such as word processing, gaming, data analysis, and more.

It can be thought of as the non-tangible component of a computer system that is responsible for performing various tasks and providing functionality to the user.

Why we need software?

Software is needed because it provides the instructions that computers use to perform tasks and provide solutions to problems.

We need software for a variety of reasons, including:

To interact with hardware

  • A computing device is made up of many several components of hardware (like CPU, ram, hard disk, motherboard, mouse, keyboard, etc.) together working as a single machine. All these computer hardware devices cannot work together on its own. To work all these components together, we have to give instructions to all these components to work together. So we need software to give instructions to all these components.
  • Without software, a computer or any computing device is just a piece of garbage. Any function of the computer is done by software. Software gives a life to a computer machine so all the physical devices work together like one body.
  • Simple Example of hardware and software of humans, Humans have eyes, ears, legs, hands, and other internal organs, so these are the part of hardware because they are physical and tangible. All the thinking is the part of software. We think consciously or unconsciously and store information in our brain is part of software which is responsible to function all our hardware part of body.

To perform tasks

A computer needs software to perform tasks, such as opening and editing documents, playing games, and accessing the internet. Without software, a computer would simply be a collection of hardware components and would not be able to perform any useful tasks.

To provide user interface

Software provides the user interface that allows us to interact with the computer and its applications. This can be a graphical user interface, such as the one provided by Windows or macOS, or a command-line interface, such as those used in Unix and Linux systems.

To manage data

Software is also responsible for managing and storing data, such as files and documents, in a way that is accessible and secure.

To run applications

A computer needs software to run applications, such as email clients, word processors, and web browsers. These applications provide the functionality that makes a computer useful for various tasks and activities.

“In conclusion, software is essential for a computer to function and to provide value to its users. It acts as an interface between the hardware components and the user, enabling us to perform tasks, manage data, and run applications.”


PurposeHardware provides the physical components that make up a computerSoftware provides the instructions that tell the hardware what to do.
FunctionalityHardware provides the basic computing power, storage, and input/output capabilitiesSoftware provides the applications and operating system that allow a computer to perform specific tasks.
UpgradabilityHardware components can be upgraded or replaced as technology advancesSoftware can be updated or replaced to add new features or fix bugs.
CustomizabilityHardware components are generally fixed and cannot be customizedSoftware can be customized to meet specific needs and requirements.
InteractionHardware components are typically controlled by softwareSoftware interacts with the hardware to perform tasks and manage data.

Types of Software

Software can be divided into two main categories: system software, which provides basic functions for “the computer and its hardware”, and application software, which performs specific tasks for users.

System Software

System software are the software for the system means these software helps the whole computer system to work all components together as a whole body.

These software are the center between user and hardware devices.

System software helps to control and manage the hardware devices. All the functions performed by computer hardware is only possible by system software.

Operating System

Operating system is the system that operates the whole computer system. It controls computer hardware devices and provides a user interface so the users can work on the computer.

Operating System provides an interface between users and hardware. It provides a friendly environment for the users so the users can work on computer without too much thinking.

Operating System as a resources manager

All the hardware resources (like CPU, ram, motherboard, hard drives, etc.) together create a computer system and operating system manage all these resources and provide a working environment to the users.

Operating system does not only provide a working environment, but it also manages all the files, memory, process of the computer. It is also responsible for the security of the system.

Basic functions of the operating system

  • File Management
  • Device Management
  • Memory Management
  • Process Management
  • Provides Security
  • Coordination between other software and users
  • Error detecting aids
  • Control over system performance
  • To handle deadlock conditions

Application Software

Application software are those software which are used by end-users to solve their specific problems. These types of software are developed to satisfy the end user’s needs.

These types of software are installed on the operating system and designed to complete specific tasks for uses.

Some examples of application software

  • Word processing software: Microsoft WordPad, Excel, PowerPoint, notepad, etc.
  • Web browsers: Chrome, Firefox, Internet Explorer, Opera, UC browser, etc.
  • Media players: VLC Player, Window Media Player, etc.
  • Console games: GTA, Battlefield, Counter-Strike, PUBG, etc.
  • Photo editors: Photoshop, GIMP, CorelDraw
  • Video editors: Adobe Premiere Pro, Filmora, Camtasia Studio, etc.

Frequently Asked Questions

what is software and hardware?

Software refers to the set of programs, data, and instructions that run on a computer and provide specific functionality and control. It includes the operating system, which provides the foundation for a computer’s operation, as well as applications and utilities that perform specific tasks, such as word processing, web browsing, and video editing. Software is written in programming languages and can be installed, updated, or uninstalled as needed.
Hardware refers to the physical components of a computer, including the motherboard, processor, memory, storage, and input/output devices. These components provide the basic computing power and storage capacity that software relies on to perform its tasks.
The hardware components of a computer can be divided into two categories: internal components, such as the processor and memory, which are housed within the computer case, and external components, such as the keyboard, mouse, and display, which connect to the computer through ports and cables.
In summary, hardware provides the physical components that make up a computer, while software provides the programs, data, and instructions that control the hardware and perform specific tasks. The two work together to form a complete and functional computer system.”

What if we don’t have any software?

Limited functionality: Without software, a computer would not be able to perform tasks such as word processing, web browsing, or playing games. It would be limited to basic calculations and data storage.
No user interface: Without software, there would be no graphical user interface or command-line interface, making it difficult for users to interact with the computer.
Inability to manage data: Without software, a computer would not be able to store, organize, or retrieve data effectively. This would make it difficult for users to access and manage their files and documents.
Inability to connect to the internet: Without software, a computer would not be able to access the internet or communicate with other devices.
No security: Without software, a computer would not have access to security tools such as firewalls, antivirus programs, or encryption software, making it vulnerable to cyberattacks and data loss.
In conclusion, software is essential for a computer to function and provide value to its users. It enables us to perform tasks, manage data, and interact with the computer and other devices in a user-friendly way.”
