How does an XOR logic gate produce a 1?

An XOR (exclusive OR) logic gate produces a output of 1 when its two inputs are different, meaning one input is 0 and the other is 1. This is a fundamental property of the XOR operation, which is often used in digital circuits and binary arithmetic.

When both inputs are different, the XOR gate evaluates to true, signifying that either one condition or the other is satisfied, but not both. For example, if the inputs are 1 and 0, the output would be 1, and similarly for 0 and 1. In contrast, if the inputs are the same—both 0 or both 1—the output is 0, indicating that neither of the exclusive conditions is met. This unique behavior of producing an output of 1 only when the inputs differ is what characterizes the XOR gate.
