What Is A Personal Computer?
A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end-user with no intervening computer operator. This contrasted with the batch processing or time-sharing models which allowed larger, more expensive minicomputer and mainframe systems to be used by many people, usually at the same time.
The PC is a complex machine. It's made up of various concepts so we've provided an at-a-glance look at what makes up a typical personal computer. You will learn how to identify components, gain an understanding of what data is all about, and learn all about system busses and what they are used for.
