XOR (Exclusive OR) is a boolean logic operator defined by its truth table. It outputs 1 when inputs differ and 0 when they are the same. XOR has several interpretations: it can mean “exclusive or,” “not equals,” or can be seen as conditional inversion or parity operations. It possesses properties like commutativity, associativity, and identity with 0. Bitwise XOR extends these properties to integers, offering applications in cryptography, graphics, and error-correcting codes. In cryptography, XOR combines plaintext with a keystream for encryption. In pixel graphics, it allows for reversible drawing operations that are efficient in memory use. Overall, XOR is crucial to computer science for its simplicity and utility in various operations.
