Pardon the dust! This page includes some jargon that hasn't been added to the site's glossary yet. I'll be around to fix this later, but sorry for the inconvenience in the meantime. |
Glossary Entry: DOS
Definition
DOS, short for Disk Operating System, was one of the earliest operating systems available for home computers. Microsoft's version, known as MS-DOS, was the most popular variant, and was little more than a command line.
MS-DOS was later replaced by Microsoft Windows. While early versions of Windows were able to run DOS programs, this ability was later dropped. Today, you'll need to use a DOS emulator or a virtual machine running a DOS operating system in order to run those old programs.
