Question

_______ is also called vertical redundancy check, one of the types of error detection in communications.
1. Longitudinal check
2. Sum technique
3. Parity checking
4. Cyclic check

Answer 1

Correct Answer - Option 3 : Parity checking

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.
