Which of the following gate is called the universal gate?
OR gate
AND gate
NAND gate
NOT gate
A universal gate is a logic gate that can be used to construct all other basic logic gates (such as AND, OR, and NOT gates) without needing any other type of gate. In digital electronics, the NAND gate and the NOR gate are the two universal logic gates. Among the given options, the NAND gate is the universal gate.
