History of the transistor - Wikipedia
A transistor is a semiconductor device with at least three terminals for connection to an electric circuit.In the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits.The transistor replaced the vacuum
