Answer / guest
Answer: A
A redundancy check detects transmission errors by appending
calculated bits onto the end of each segment of data. A
reasonableness check compares data to predefined
reasonability limits or occurrence rates established for the
data. A parity check is a hardware control that detects data
errors when data are read from one computer to another, from
memory or during transmission. Check digits detect
transposition and transcription errors.
