- noun a logical function whose output is true if any input is true and false if all the inputs are the same.
- A logical operation which is false if all of its elements are the same. For example, if all of its multiple inputs have a value of 0, then the output is 0. And, if all of its inputs have a value of 1, then the output is 0. Any other combination yields an output of 1. For such functions, a 1 is considered as a true, or high, value, and 0 is a false, or low, value. Its abbreviation is XOR. Also called exclusive OR operation.
