Which basic digital logic gate performs conjunction?

Explanation:
Conjunction means both inputs must be true for the result to be true. In digital logic, that’s exactly what the AND gate does: its output is high only when both inputs are high. If either input is low, the output is low, matching the truth table 0/0 → 0, 0/1 → 0, 1/0 → 0, 1/1 → 1. The other gates don’t fit this rule: OR gate outputs high if any input is high, NAND is the inverted form of AND, and XOR outputs high only when the inputs differ. Therefore, the gate that performs conjunction is the AND gate.
