AND/OR/NOT

What are AND/OR/NOT gates?

AND/OR/NOT are the three fundamental logic gates that form the building blocks of digital circuits and computer systems. AND gates output HIGH only when all inputs are HIGH, OR gates output HIGH when any input is HIGH, and NOT gates (inverters) output the opposite of their single input. These gates process binary signals (0s and 1s) and can be combined to create complex logical operations, memory systems, and computational functions in microprocessors, controllers, and digital devices.

Logic Gate

A logic gate is a fundamental digital circuit component that performs basic logical operations on one or more binary inputs to produce a single binary output. It implements Boolean algebra functions such as AND, OR, NOT, NAND, NOR, XOR, and XNOR, where inputs and outputs are represented as high (1) or low (0) voltage levels. Logic gates are the building blocks of all digital systems, from simple circuits to complex processors, and can be implemented using various technologies including transistors, diodes, or integrated circuits.
