Logo of MS-DOS

MS-DOS (Microsoft Disk Operating System) is an operating system for x86 based personal computers. It was based on 86-DOS (Quick and Dirty Operating System), also known as 86-DOS, which was made by Tim Paterson and purchased by Microsoft. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for personal computers during the 1980s and 1990s. It was preceded by M-DOS (also called MIDAS), designed and copyrighted by Microsoft in 1979. MS-DOS was written for the Intel 8086 family of microprocessors, particularly the IBM PC and compatibles. An MSX port was also made, called MSX-DOS.

It was gradually replaced on consumer desktop computers by operating systems offering a graphical user interface (GUI), in particular by various generations of the Microsoft Windows operating system. It is still used by a tiny market niche where legacy DOS applications are still required, but no modern version is available.

Microsoft and IBM both had their own versions of MS-DOS. There are not many differences between the two versions before the split up, when IBM started developing PC-DOS independently of Microsoft. IBM distributed their version of MS-DOS first as IBM DOS (prior to version 5.0), and later on as IBM PC-DOS.
