Operating systems

The main operating systems for microcomputers are Windows, UNIX, Linux and OS/2. Each is designed for specific microprocessors.

Windows runs on the IBM family of computers using Intel microprocessors. Windows provides a graphical user interface (GUI) that lets the users select from icons that show the choices. Windows also provides multitasking: several application programs are running at the same time. OS/2 is IBM-compatible. It can run application programs written for Windows, and it provides a graphical interface. It is also multitasking.

UNIX can work with different microprocessors, but each microprocessor requires a different version, and the versions are incompatible. UNIX provides multitasking, which allows several users to share some programs at one time.
