What does a NOR logic gate output when both inputs are 0?

• A. 1
• B. 0
• C. Depends on the input states
• D. Only for binary inputs

Answer: (A)

A NOR logic gate is a combination of an OR gate followed by a NOT gate. It performs a logical operation where the output is true (1) only when all of its inputs are false (0). When both inputs to a NOR gate are 0, the OR operation first results in 0 (since 0 OR 0 is 0). The NOT operation then inverts this output, changing it to 1. Therefore, the NOR gate outputs 1 when both inputs are 0, which confirms that the reasoning for choosing this option is accurate. Understanding this behavior is essential as it highlights the fundamental operation of NOR gates in digital logic design, where they are often utilized for creating complex logic circuits and implementing functions.
