DOS is a general acronym for "Disk Operating System", though it came to refer to the operating system used in the IBM PC, particularly Microsoft's MS-DOS.
This tutorial looks at DOS Internal Commands, which in some sense are analogous to shell commands in Linux. That means that the command interpreter already has these loaded and ready to go when you boot.
