Vertical Redundancy Check

(storage, communications)(VRC) An error checking methodperformed on one 8-bit ASCII character, where the 8th bit isused as the parity bit.

The resulting parity bit is constructed by XORing theword. The result is a "1" if there is an odd number of 1s,and a "0" if there is an even number of 1s in the word. Thismethod is unreliable because if an odd number of bits aredistorted, the check will not detect the error. TheLongitudinal Redundancy Check is an improvement.

vertical redundancy check

An error checking method that generates and tests a parity bit for each byte of data that is moved or transmitted. See longitudinal redundancy check.
