A transistor computer is a computer system built primarily using discrete transistors. Transistor computers completely obsoleted much of the earlier computer technologies such as relays and vacuum tubes by the mid 1960s. By that time computers started to be classified according to their size, price, and capabilities. Systems fell into either mainframe computers, minicomputers, and microcomputer. Starting from the 1970s, the microprocessor superseded the older discrete logic systems.
