What is logic gate?

Explanation

A logic gate called the digital circuit of something more important than certain types of logic functions.
A gate is a digital circuit that follows certain logical relationship between the input and output voltages. They are known as logic gates.
Gates because they control the flow of information.
The five common logic gates used are NOT, AND, OR, NAND, NOR. Each logic gate is indicated by a symbol and its function and its behaviour is understandable with this truth table. Means, truth table is useful for understanding the behaviour of logic gate.
Truth table: It is a table that shows all possible input combinations and the corresponding output combination for a logic gate.
The Boolean equation is called the logic representation of a particular types of logic gate operation.
Semiconductor devices are useful to understand the function of logic gate.
