What is the output of a NOR gate when both inputs are high?

A NOR gate is a digital logic gate that outputs true or high only when both of its inputs are false or low. In the context of this question, if both inputs are high, the NOR gate will output false. This aligns with the fundamental operation of the NOR gate, which combines the functions of an OR gate followed by a NOT gate.

When both inputs are in the high state, the OR operation would yield high, and then the NOT gate would invert that output, resulting in a low or false output. Thus, the output of the NOR gate when both inputs are high is indeed false.

Understanding the operation of a NOR gate is crucial in digital logic design as it helps in simplifying circuit designs and understanding more complex logic functions, which are foundational in IT support and circuit functionality.
