What is a logic gate?

A logic gate is a device (either virtual or mechanical) used to execute a Boolean function. Logic gates are the bedrock of modern computing.

Logic gates can be divided into two categories: 1- input logic gates 2- input logic gates

The 1-input logic gates are:

• Buffer
• Inverter

The 2- input logic gates are:

• AND
• NAND
• OR
• NOR
• XOR
• XNOR
