What is a Personal Computer (PC)
Today's reality is that, although IBM clearly designed or architectured and invented the PC in 1981 and controlled the improvement or development and evolution of the PC standard for some years then, IBM has no longer in control of modification of the PC standard. It does not instruct what makes up a PC today. In 1987 IBM lost control of the PC standard when it introduced its PS/2 line of systems. Up until then, other companies that were producing PCs direct copied IBM’s systems right down to the chips, connectors, and even the shapes of the boards, power supplies, and cases. After 1987, IBM abandoned many of the standards it created in the 1st place, and the designation “IBM compatible” started to be considered obsolete.
If a Personal Computer or PC is no longer defined as an IBM-compatible system, then what is it? The real question think to be, “Who is in control of the PC standard today?” If we go deep into that question, it breaks down into two parts. First, who is in control of the PC software? Second, who is in control of the PC hardware?
