D)cyclic redundancy check

Question

Quizplus · Accepted Answer

A cyclic redundancy check (CRC) is a type of error-detecting scheme that uses a unique prime number to detect errors. It involves the generation of a short, fixed-length check value or summary based on the data being transmitted, which is appended to the message and then transmitted. The receiver then performs the same calculation on the received data and compares it to the check value to determine whether any errors occurred during transmission.
