MS-DOS (Microsoft Disk Operating System) is a non-graphical, command line operating system that was widely used on IBM PC-compatible computers in the 1980s and early 1990s. It provided basic functions for managing files, running software, and interacting with hardware. Users typed commands to perform tasks such as copying files, starting programs, and configuring the system. It was a dominant OS before the widespread adoption of graphical user interfaces like Windows.
