Types of computer system. The hardware. The operating sytem. The utilities. The application programs. End users Utilities  are the small programs that provide an addition to the capabilities provided by an operating system. Generally utilities perform a specific task related to managing the system resources. Operating systems contain a number of utilities for managing disk drives, printers, and other devices. Utilities are installed as memory resident programs that assist in system management. These utilities are essential and critical to modern computer environments. They perform the important tasks such as disk optimization and anti-virus protection. Most system utilities are installed, configured and periodically updated for a specific computer configuration. Application programs  are the computer programs which are used for the purpose of performing specific tasks using a computer. Application programs define the ways in which the system resources are used to solve th
