DOS

The acronym DOS stands for disk operating system, an operating system component for computers that provides the abstraction of a file system resident on hard disk or floppy disk secondary storage. In some cases, the disk operating system was called DOS, and on the PC compatible platform, an entire family of operating systems was called DOS.

In particular, DOS refers to the family of closely related operating systems which dominated the IBM PC compatible market for the decade between 1985 and 1995: PC-DOS, MS-DOS, DR-DOS, FreeDOS, OpenDOS, PTS-DOS, and several others. Of these, MS-DOS from Microsoft became the most widely used.

MS-DOS (and the IBM PC-DOS which was licensed therefrom), and its predecessor, QDOS, was a successor to CP/M (Command Processor / (for) Microcomputers)—which was the dominant operating system for 8-bit Intel 8080 and Zilog Z80 based microcomputers.
