Operating systems


An operating system (O/S) is a computer’s primary control program. The O/S, manages the allocation of resources among application programs, including memory and cpu-cycles, and provides common services such as reading and writing to disk, keyboard input and display screen output. Most computer-based devices from mainframes to PCs and smart phones use an O/S. Operating systems in common use include versions of MS Windows, many versions of Linux and Unix, Macintosh OS X and IBM’s i5/OS and z/OS.
