A computer system comprises hardware and software components, aiming to offer a powerful computational tool. These systems play a crucial role across diverse domains, aiding us in numerous tasks. The prevalence of the internet has significantly bolstered the utilization of computers for information sharing and communication. Computer systems empower us to store, process, display, and transmit information. Even in a basic modern computer system, multiple programs are typically required to carry out various functions effectively.

Utility Programs

The utility programs is a type of system software that allows a user to perform maintenance-type tasks, usually related to managing computer, its devices, or it programs.

The utility programs for large computer systems are designed for professional system programmers to either modify or repair the system software. Many utility programs such as programs for finding files, diagnosing and repairing system problems, cleaning up a hard drive, viewing images, playing multimedia files and backing up files. It also helps to secure and safeguard data.

However the utility programs for microcomputers are very often used by end users.

They are user friendly and designed for end users, change the monitor’s background pattern, or install computer hardware. It is a software program that performs a specific task, usually related to managing or maintaining a computer system.

Most operating system include several built-in utility programs. Some of the principal utility programs are as follows:
