How does a NOR gate differ from an OR gate?

A NOR gate is a digital logic gate that outputs true (1) only when both of its inputs are false (0), effectively functioning as an inverted OR gate. In contrast, an OR gate outputs true if at least one of its inputs is true. Therefore, while the OR gate produces a high output for any combination of high inputs, the NOR gate will only produce a high output when all inputs are low. This means the NOR gate combines the functions of an OR gate with a NOT gate.
