Parity bit

Parity bitA parity bit is a single bit added to a binary data transmission used to indicate if whether the 0's and 1's within that data transmission is an even or odd number. The parity bit is used in parity error checking to find errors that may occur during data transmission. The picture is an example of a 8-bit binary number with the ninth digit being the parity bit.
