Q80 / 100
What is the significance of "checksum" or "CRC" (Cyclic Redundancy Check) fields in embedded communication protocols?
Correct! Well done.
Incorrect.
The correct answer is A) They allow the receiver to detect data corruption that may have occurred during transmission (e.g., due to electrical noise), by comparing a computed checksum against the received one
A
Correct Answer
They allow the receiver to detect data corruption that may have occurred during transmission (e.g., due to electrical noise), by comparing a computed checksum against the received one
Explanation
CRC and checksum values are computed from the data before transmission and recomputed by the receiver; a mismatch indicates the data was corrupted in transit, allowing the receiver to request retransmission or discard the bad data.
