Document Summary

System software consists of two primary types of programs: the operating system and utility programs. Operating system (os) is the main program that controls how your computer system functions. Os manages the computer"s hardware, including the processor, memory, and storage devices, as well as peripheral devices. Provides a consistent means for software applications to work with the central. Responsible for the management, scheduling, and interaction of tasks. You access the operating system through the desktop on your computer. Utility programs small programs that perform many of the general housekeeping tasks for the computer, such as system maintenance and file compression. These types of operating systems are used in devices that perform a repetitive series of specific tasks. These devices may or may not require interaction with users and may be time critical. The type of os is used for devices which run only one application program: example: an atm which has limited set of financial transactions it can run.
