DOS
_on_Bochs_sshot20040912.png?width=300)
DOS /dɒs/, short for disk operating system, is an acronym for several computer operating systems that were operated by using the command line.MS-DOS dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 including the partially MS-DOS-based Microsoft Windows (95, 98, and Millennium Edition). ""DOS"" is used to describe the family of several very similar command-line systems, including MS-DOS, PC DOS, DR-DOS, FreeDOS, ROM-DOS, OSx16, ""Horizon OS"" and PTS-DOS. In spite of the common usage, none of these systems were simply named ""DOS"" (a name given only to an unrelated IBM mainframe operating system in the 1960s). A number of unrelated, non-x86 microcomputer disk operating systems had ""DOS"" in their names, and are often referred to simply as ""DOS"" when discussing machines that use them (e.g. AmigaDOS, AMSDOS, ANDOS, Apple DOS, Atari DOS, Commodore DOS, CSI-DOS, ProDOS, and TRS-DOS). While providing many of the same operating system functions for their respective computer systems, programs running under any one of these operating systems would not run under others.
