PC means...

In its more general usage, a PC (personal computer) is a computer designed for use by one person at a time. Prior to the PC, computers were designed for (and only affordable by) companies who attached terminals for multiple users to a single large computer whose resources were shared among all users. Beginning in the late 1980s, technology advances made it feasible to build a small computer that an individual could own and use. The term "PC" is also commonly used to describe an "IBM-compatible" personal computer in contrast to an Apple Macintosh computer.
