MS-DOS

Article summary

MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) i s an operating system for x86-based personal computers mostly developed by Microsoft.

MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and released it in 1981 as PC DOS 1.0 for use in its IBM Personal Computer. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS, several competing products were released for the x86 platform. Initially, MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well.…
