What does Vertical Redundancy Check (VRC) mean?
Vertical redundancy check (VRC) is an error-checking method used on an eight-bit ASCII character. In VRC, a parity bit is attached to each byte of data, which is then tested to determine whether the transmission is correct. VRC is considered an unreliable error-detection method because it only works if an even number of bits is distorted.
A vertical redundancy check is also called a transverse redundancy check when used in combination with other error-controlling codes such as a longitudinal redundancy check.
Techopedia explains Vertical Redundancy Check (VRC)
VRC is a redundancy check meant for parallel synchronized bits applied one bit at a time. It uses additional parallel channels for check bits and refers to single-parity bits or larger hamming codes.
Although parities are only meant for error detection and not error correction, they still can remain part of a system for correcting errors.
