what is logic gate

A logic gate is an electronic circuit that performs a Boolean function, which is a logical operation on one or more binary inputs that produces a single binary output. These gates are the basic building blocks of digital circuits and are fundamental to the operation of computers and other digital devices. There are several types of logic gates, including AND, OR, XOR, NOT, NAND, NOR, and XNOR gates, each of which performs a specific logical operation based on the input signals it receives
