A three terminal semiconductor electronic device is called a transistor. Transistors are widely used in electronic appliances such as computers, radio, audio video equipment, biomedical instrument etc. A transistor is a three layer semiconductor which consists a very thin central layer of one type of semiconductor material sandwiched between two relatively thick layer of second type. A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
