What does a transitor mean?

Answer 1

A transistor is a semiconductor device that can amplify or switch electronic signals and electrical power. It consists of three layers of semiconductor material, typically arranged as either NPN or PNP, which control the flow of current between two terminals based on the voltage applied to a third terminal. Transistors are fundamental components in modern electronics, enabling the operation of everything from small gadgets to large computing systems. They are essential for functions such as signal modulation, amplification, and digital logic operations.
