The MS-DOS logo

DOS, which stands for Disk Operating System, refers to a series of text-based operating systems used by early computers. Many companies had their own version of DOS across many platforms, but Microsoft's MS-DOS (released in 1981 for IBM PCs) is the most ubiquitous, and what most people refer to when talking about DOS in general. The last standalone release of MS-DOS was version 6.22, although updated versions of it were embedded into Windows 9x and ME.
