DOS
- DOS
- 1. Disk Operating System. The original command line based operating
system used on IBM personal computers and
compatibles. Technically PC-DOS refers to the version of DOS used on IBM
computers and MS-DOS the version of DOS used on compatible clones from
other manufacturers. Both PC-DOS and MS-DOS were written by Microsoft
and were essentially identical.
DOS predates Windows. Earlier versions of Windows (notably Windows 9x) provided the option to restart in "DOS mode". Current Windows versions still support a "Command Prompt", which provides a DOS like interface.
