DOS, or Disk Operating System, was the primary operating system used on IBM PCs in the 1980s and early 1990s. It featured a command-line interface where users could type in text commands, and it displayed a prompt like C:\ to indicate where the user could enter commands. HTML is a markup language used for creating web pages, while Unix and Linux are both operating systems that use a command-line interface, but were not originally installed on IBM PCs.
