Expert
It is the least expensive and most common mechanism for Error Detection in VRC. For even parity the total number of 1s becomes even, if a parity bit is added to every data unit. VRC can detect all single-bit errors but it can detect burst errors only if the total number of errors in each data unit is odd.
