DOS and PC DOS are different. When we say DOS, it means Microsoft DOS or MS DOS whereas PC DOS is the different operating system (older than MS-DOS) developed by IBM. The term "DOS" is the acronym for Disk Operating System. This is the main control software that makes the computer start up and commence other loading functions. As stated PCDOS is in fact the same, an operation system and can refer to may of the older languages used when comouters were first developed such as Amiga DOS, Fast DOS etc.
