A Bipolar Junction Transistor (BJT) is a three-terminal semiconductor device that can amplify signals. It's a current-controlled device that consists of two p-n junctions, a common region called the base, and two outer regions called the emitter and collector. 

BJTs are known as bipolar transistors because they involve the operation of charge carriers of both polarities. They can function as current regulators by allowing a small current to control a larger current. 
BJTs can consist of either a P-N-P or an N-P-N semiconductor “sandwich” structure. In a PNP transistor, the regions are, respectively, p type, n type, and p type. In an NPN transistor, the regions are n type, p type, and n type.
