Basic gates -A logic gate is a simple switching circuit that determines whether an input pulse can pass through to the output in digital circuits. 

A logic gate is a digital gate that allows data to be transferred. Logic gates, use logic to determine whether or not to pass a signal. Logic gates, on the other hand, govern the flow of information based on a set of rules. The following types of logic gates are commonly used:

1. AND
2. OR
3. NOT
4. NOR
5. NAND
6. XOR
7. XNOR
