Where is used ms-dos?

MS-DOS (Microsoft Disk Operating System) was primarily used as an operating system for personal computers in the 1980s and early 1990s. It provided a command-line interface for users to interact with their computers, manage files, and run software applications. Although largely replaced by more advanced graphical operating systems like Windows, MS-DOS is still utilized in some embedded systems, legacy software environments, and for specific tasks in programming and system recovery.
