'''MS-DOS''' (Microsoft Disk Operating System) is a monolithic singletasking operating system developed by [[w:Microsoft|Microsoft]] between 1980 and 2000 for [[w:x86|x86]]-based personal computers. It was the ''de facto'' industry standard environment on the IBM PC and its clones, although it also shipped with many x86-based computers that were otherwise incompatible with IBM. | '''MS-DOS''' (Microsoft Disk Operating System) is a monolithic singletasking operating system developed by [[w:Microsoft|Microsoft]] between 1980 and 2000 for [[w:x86|x86]]-based personal computers.

By default, MS-DOS is driven by a command line interface; the <code>A></code> or <code>C:\></code> prompt shown when the command processor is ready to accept input ultimately became one of the unofficial symbols of DOS. Several software vendors have developed programs that add a more friendly user interface to manage files and launch other programs. | By default, MS-DOS is driven by a command line interface; the <code>A></code> or <code>C:\></code> prompt shown when the command processor is ready to accept input ultimately became one of the unofficial symbols of DOS.

Microsoft itself included such a program, the MS-DOS Shell, with some versions of MS-DOS. | ||
There is very limited support for running multiple programs simultaneously in MS-DOS. The operating system allows a program to terminate and stay resident (TSR), meaning that a portion of the program's code can stay present in memory and be triggered by an API call or a hardware interrupt even after the base program exits. A proper [[Multitasking MS-DOS 4|multitasking version]] of MS-DOS was produced in 1986, which shipped to a limited number of OEMs and eventually evolved into [[OS/2]]. | There is very limited support for running multiple programs simultaneously in MS-DOS.
