How many outputs does an AND logic gate have?

• A. Two
• B. One
• C. Three
• D. Four

Answer: (B)

In digital logic, a gate’s output is a single signal that represents the result of its operation on the inputs. An AND gate computes the logical conjunction of its inputs, and it delivers one output signal that goes high only if all inputs are high. Even if the gate has more than two inputs, the output remains a single line—the AND of all inputs. So the number of outputs is one. The other counts would imply multiple separate results from the same gate, which isn’t how standard AND gates are defined.
