This page provides all possible meanings and translations of the word MS-DOS
MS-DOS, Microsoft disk operating system(noun)
an operating system developed by Bill Gates for personal computers
MS-DOS is an operating system for x86-based personal computers. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s to the mid-1990s, until it was gradually superseded by operating systems offering a graphical user interface, in particular by various generations of the Microsoft Windows operating system. MS-DOS grew out of a request placed by IBM in 1981 for an operating system to use in its IBM PC range of personal computers. Microsoft quickly bought the rights to QDOS, also known as 86-DOS, from Seattle Computer Products, and began work on modifying it to meet IBM's specification. The first edition, MS-DOS 1.0, was launched in August 1981. The version shipped with IBM's PCs was called PC DOS. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products eventually went their separate ways. During its life, several competing products were released for the x86 platform, and MS-DOS itself would go through eight versions, until development ceased in 2000. Ultimately it was the key product in Microsoft's growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI. It is a flexible operating system, and consumes only 8 MB of installation space.
