There are seven basic logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR.
The NAND gate operates as an AND gate followed by a NOT gate.
The output is "false" if both inputs are "true." Otherwise, the output is "true."
The XNOR (exclusive-NOR) gate is a combination XOR gate followed by an inverter. Its output is "true" if the inputs are the same, and"false" if the inputs are different.
