A bipolar junction transistor ( BJT ) has terminals labeled base, collector, and emitter. For a field-effect transistor ( FET ) , the terminals are labeled gate , source, and drain, and a voltage at the gate can control a current between source and drain.
A diode is a two-terminal semiconductor device that consists of a PN junction made of semiconductor material.
An integrated circuit ( IC ) , sometimes called a silicon chip or chip, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated.
