bitwise operators operate at bit level on whole numbers: they are the fastest operations to be done on whole numbers... xor operator works as: 1 xor 1 = 0 1 xor 0 = 1 0 xor 1 = 1 0 xor 0 = 0 so xor is used as a mask wich invert bits where bit is set and leave bits unchanged where bit is not set... at a very low level, all instructions are done using combined/chained bitwise operators (each is a specialized electronic transistor wich compound nowadays microprocessors by more of 10 billions)
