A NOT gate (also often called Inverter) is a logic gate. Each NOT gate has only one input signal. Logically with NOT gates, the input and the output swap, so if you input 1 it outputs as 0; likewise if you input 0 it outputs as 1.

In the 20th century an inverter was often made of a discrete transistor with other components, or several inverters were packaged in an integrated circuit.
