Parity is a method of checking the correctness of the code transmission. Be transmitted according to a set of binary digital code of " 1" bits is odd or even to verify. Using odd as odd parity, and vice versa, as even parity. What kind of validation is specified in advance good. Usually set up a dedicated parity bit, it makes this group code " 1" is odd or even. If using odd parity, then when the receiver receives this set of code, check the " 1" if the number is odd, to determine the transmission code is correct.
