(loj´ik gāt)
(n.) A type of
circuit (or collection of
transistors and
resistors) that regulates the flow of electricity (or optical signals in
fiber optic computing systems) that determines the
Boolean logic computers use to make complex logical decisions. The three simple gates—AND, OR and NOT—combine to perform complex decision making processes. The
on or
off state of a logic gate corresponds to the
binary values.
The complex logic gates are XOR (exclusive-OR), NAND (NOT-AND), NOR (NOT-OR), and XNOR (exclusive-NOR).
