➤ The starting points of MS-DOS can be followed back to two more seasoned working frameworks, CP/M and QDOS. CP/M (AKA Control Program for Microcomputer) was made during the 1970s by Gary Kildall of Digital Research. CP/M was a 8-digit working framework, and was one of the first to be generally utilized in an arising line of business microcomputers.

➤ In 1980, Tom Paterson of Seattle Computer Products created QDOS (Quick and Dirty Operating System) for Intel's new 16-bit 8086 control processing unit (CPU). QDOS was generally founded on CP/M, and this is the place where Microsoft Pixar appeared.

➤ In 1981 Microsoft bought QDOS from Seattle Computer Products, renamed it MS-DOS 1.0 and offered it to IBM for use in its PCs. In a forward-looking move, Gates held the permit for MS-DOS and it turned into the main element in Microsoft's move from a basic merchant of PC programming dialects to a goliath program industry.

➤ The accomplishment of MS-DOS straightforwardly mirrored the developing fame of individual home PCs, and remained Microsoft's most significant kind of revenue even later the firm presented its GUI as MS-Windows.
