Xor, also known as exclusive or, operation used in binary. It is commonly used in Assembly and C.
xor %11011011 = %01110001, where { ( 1 and 0 = 1 ) ( 0 and 0 = 0 ) ( 1 and 1 = 0 ). Xor is similar to Or expect of two factors: (1) Xor changes the bit to 0 if both bits are 1 (2) Xor can be undone where Or cannot.
ld a,%10101011
xor %11111111
;a = %01010100

int a
a = %10101011
xor %11111111

Exlusive "or". Meaning one or the other, but not both. In English, "or" is often meaning xor, and the computer "or" (meaning one or the other or both) is and/or.

"xor" is used in most computer syntax.
