What is the output of an OR gate when both inputs are 0?

• A. 0
• B. 1
• C. 2
• D. Error

Answer: (A)

In the context of digital logic, an OR gate is a basic logic gate that outputs a 1 (true) if at least one of its inputs is 1 (true). Conversely, the OR gate outputs a 0 (false) only when all of its inputs are 0 (false). When both inputs to the OR gate are 0, the condition for the gate to output a 1 is not met since neither input is true. Therefore, the output must be 0, which corresponds to the scenario where the OR gate receives no positive input signal. This behavior is critical in digital circuits, as it allows for simple decision-making processes based on binary input states.
