When it comes to operating a computer, there are various software programs that come into play. These software programs are designed to control and manage various aspects of the computer. In this article, we will take a closer look at some of the main software programs that control the computer.

Operating System Software

The operating system (OS) is the most critical software program that controls the entire computer. It acts as an intermediary between the hardware components and the applications that run on them. The OS manages memory allocation, file systems, input/output operations, and network connectivity.

There are several types of OS available in the market such as Windows, macOS, and Linux. Each OS has its unique features and benefits. For example, Windows is known for its user-friendly interface, while Linux is preferred for its stability and security.

Application Software

Application software refers to any program or group of programs that performs a specific function on a computer. This includes productivity tools like word processors, spreadsheets, and presentation software; media players; graphic design tools; video editing software; and many more.

These applications are developed by third-party developers or in-house teams to meet specific needs or requirements. They use APIs provided by an operating system to interact with hardware components like printers and scanners.

Device Drivers

Device drivers are small software programs that allow hardware devices to communicate with the operating system. Without device drivers, peripherals like printers or scanners would not work correctly.

Most device drivers come pre-installed with an operating system while others need to be installed manually by downloading them from the manufacturer’s website.

Utility Software

Utility software is a type of system software designed to optimize performance or solve problems on a computer. Examples of utility software include antivirus programs, disk defragmenters, registry cleaners, backup tools, and more.

These programs help users maintain their computers and ensure they run smoothly. They can be pre-installed on an operating system, or users can download them from third-party websites.


In conclusion, the software programs that control a computer are essential for its operation and maintenance. From the operating system to application software, device drivers, and utility software, each of these programs plays a crucial role in ensuring that the computer runs optimally.

It’s essential to keep these programs updated and well-maintained to prevent any issues or errors from arising. By doing so, users can enjoy a seamless computing experience while using their computers for work or entertainment.
