Which of the following is the mathematical calculation that is used to verify the validity of a packet?
A.
Cyclical redundancy check (CRC).
B.
Open system interconnection (OSI).
C.
Data link control. (DLC).
D.
Transmission Control Protocol (TCP).
Explanation:
The CRC is an algorithm used to calculate the validity of a packet. It is a checksum used to
determine if there are bit errors on the packet or frame.
Incorrect Answers:B: OSI is not a mathematical calculation.
C: DLC is a Data Link protocol, it is not a mathematical calculation.
D: TCP is a transport protocol, it is not a mathematical calculation.
