An error detection technique in which an extra bit, called a parity bit, is added to each byte in a transmission, holding a 0 or 1 depending on whether the byte has an odd or even number of 1 bit.The sender and receiver agree on odd parity, even parity, or no parity.If they agree on even parity, a parity bit will be added that will make each byte even.If they agree on odd parity, a parity bit will be added that will make each byte odd.
