Universal Gates:

Universal logic gates are the logic gates that are capable of implementing any Boolean function without requiring any other type of gate. There are two universal logic gates, they are – NAND, NOR. NAND gate represents the complement of AND operation. It is mainly the combination of AND and NOT gate. The output is 0 only when each of the inputs is 1. And NOR g ate represents the complement of OR operation. It is mainly the combination of OR and NOT gate. The output is 1 only when each of the inputs is 0. Using universal gates, we can construct any basic gate easily.
