Microcomputers and home computers are types of personal computers. Often, the term personal computer is used exclusively for computers running a Microsoft Windows operating system, but this is erroneous. For example, a Macintosh running Mac OS and an IBM PC compatible running Linux are both personal computers. This confusion stems from the fact that the term PC is often used as a shorthand form for IBM PC compatible and historically Mac OS has run on non-IBM compatible hardware like the PowerPC architecture.
