Cita: A personal computer (PC) is a microcomputer whose price, size, and capabilities make it suitable for personal usage. The term was popularized by Apple Computer with the Apple II in the late-1970s and early-1980s, and afterwards by IBM with the IBM Personal Computer. Personal computers are also known as home computers.
Como dice, es un termino.. no el nombre de algo... ya que lo hayan relacionado o hayan hecho eso para diferenciarlos es diferente.
Oh.. y lo que paso con IBM vino despues...
