A logic gate is a piece of electronic hardware that performs a logical (boolean) operation on one or more logic inputs and produces a single output. They’re usually made from a series of diodes or tansistors.
Logic used in computer systems is called Boolean Logic because there are only 2 possible values, TRUE or FALSE (which is represented in binary as 1 or 0)
HERE is a file in a word document displaying the logic gates and how switches that go through these gates effect an output. The graphics use were created using logic.ly .
