What unique feature does a XOR gate have compared to an AND gate?

A XOR (exclusive OR) gate is characterized by its ability to produce a HIGH output only when the number of HIGH inputs is odd. Specifically, it outputs HIGH when the inputs are different. This means that if one input is HIGH and the other is LOW, the output will be HIGH. However, if both inputs are the same (both HIGH or both LOW), the output will be LOW.

In contrast, an AND gate outputs HIGH only when all its inputs are HIGH. This fundamental difference in behavior is what sets the XOR gate apart, as it provides functionality that can be used for operations requiring the detection of differences between binary states. Therefore, the essential feature that distinguishes the XOR gate from the AND gate is its behavior regarding the relationship between the inputs, specifically that the XOR gate responds uniquely to differing input states.
