When we turn on a computer, we expect it to perform tasks and execute programs efficiently. But have you ever wondered which software is responsible for running a computer? In this article, we will explore the different types of software that are used to run a computer.

The Operating System (OS)

The Operating System (OS) is the most critical software that runs a computer. It acts as an interface between the user and the hardware components of the computer. The OS manages all the resources and processes necessary for running applications and ensuring that they all work together correctly.

There are several types of Operating Systems available in the market, with some of the most popular ones being Windows, MacOS, and Linux. Each OS has its unique features and benefits, making it suitable for various purposes like gaming, programming or graphic design.

Application Software

Application software refers to programs that are designed to perform specific tasks on a computer. These programs can be anything from word processors to web browsers or video editing software.

One of the most significant advantages of Application Software is that it provides users with a way to interact with their computers easily. Some popular application software includes Microsoft Office Suite (Word, Excel, PowerPoint), Adobe Creative Suite (Photoshop, Illustrator), and web browsers like Google Chrome or Mozilla Firefox.

Utility Software

Utility Software includes programs designed to help maintain system performance and keep it running smoothly. These tools can be used for tasks like disk cleanup, antivirus protection, backup solutions or driver updates.

Examples of utility software include CCleaner for disk cleanup, Norton Antivirus for virus protection and Acronis True Image for backup solutions.


The Basic Input/Output System (BIOS) is another critical piece of software that runs your computer’s hardware components. The BIOS is responsible for booting up your computer when you turn it on and ensuring that all hardware components are working correctly.

The BIOS is a low-level program that runs before the Operating System, making it an essential component of the computer system.


In conclusion, many different types of software are used to run a computer, each with its unique purpose and functionality. The Operating System acts as the interface between the user and hardware components, while application software and utility software perform specific tasks to improve performance.

The BIOS is responsible for booting up your computer and ensuring that all hardware components are working correctly. Understanding how these different types of software work together can help you troubleshoot issues with your computer quickly.
