The 7 pages that link to XOR gate, each with the reason it gives.
Exclusive orBroader topic: It is the hardware implementation of the exclusive-or connective.
OR gateCompared with: Unlike inclusive OR, XOR outputs false when both inputs are true.
AND gateCompared with: For two inputs, XOR is true when exactly one is true, not when both are true.
XNOR gateCompared with: XOR reverses every output of XNOR, making it the direct logical complement.
