What is a PC?
"PC" can stand for several things. In our society right now, the most common references are these:
Politically correct
Personal computer
I'm sure there are plenty of others!!

One thing it stands for is personal computer. But I'm sure there are others. For years I have heard PC used to distinguish between the "IBM" type computers and those made by Macintosh (I probably spelled that wrong). Now it refers to any brand that isn't a Mac.
PC can also be "privileged communication"
i have heard that PC has been used for those things. The first meaning to evolve was the meaning Politically correct. It can mean many other things too. For example, i have a friend whose intials are PC his name is Patrick Cannon. Another example is the personal computer which is used to store many things and is hooked up to a monitor
