Personal computer
Terminology

The term "PC" is an initialism for "personal computer". While the IBM Personal Computer incorporated the designation into its model name, the term originally described personal computers of any brand. In some contexts, "PC" is used to contrast with "Mac", an Apple Macintosh computer.

Since none of these Apple products were mainframes or time-sharing systems, they were all "personal computers" and not "PC" (brand) computers. In 1995, a CBS segment on the growing popularity of PC reported: "For many newcomers PC stands for Pain and Confusion."
