X
XOR exclusive OR. A Boolean operation that yields true
only if one of its operands is true and the other is
false. If both operands are the same (either true or
false), the operation yields false. Because the opera-
tion is bitwise, and reversed if performed twice with
the same operand, XOR is frequently used for
simple encryption, or as a part of encryption
processes.
