Since 1950, advances in semiconductor technology have had an unprecedented impact on computers. In the 1960s, computers were accessible only to big corporations, universities, and government agencies. Now "computer" has become a common word. The range of computers now available extends from such sophisticated, multimillion dollar machines as the Cray computers to the less-than-$1000 personal computers.
Different types of computers are designed to serve different purposes. Some are suitable for scientific calculations, while others are used simply for tuning appliances on and off. Until the 1970s computers were broadly classified in three categories: mainframe, mini, and micro computers. Since then technology has changed considerably, and the distinction between the categories have been blurred. Initially the micro computer was recognized as the computer with a microprocessor as its CPU.
