AI overview

DOS (Disk Operating System) is an older computer operating system that used a text-based command line instead of graphical windows, and it was the standard system for personal computers in the 1980s and early 1990s. It matters historically because it was foundational to personal computing, and versions like MS-DOS became widely used before graphical systems like Windows took over.
