+**Disk Operating System** (**DOS**) is the name of many operating systems
+starting from 1960s mainframe OSes, but most commonly it refers to
+Microsoft's MS-DOS and compatible systems running on [[IBM PC]] compatible
+hardware. [[FreeDOS]] is an actively maintained DOS-compatible operating
+system that supports things like USB memory sticks. DOSBox is a popular
+emulator for running DOS-based IBM PC programs in modern operating systems.
+
+DOS is designed to only run one program at a time with minimal external
+dependencies. It is thus quite immune to many problems of more modern OSes,
+such as [[software rot]]. It may well used as a [[bedrock platform]] or as a
+"bare-bones" system that may work for basic tasks even when everything else
+fails. The main compatibility issue in DOS is that a lot of hardware is
+commonly used by "banging the bare metal", which makes e.g. old sound
+applications incompatible with modern hardware.
