Question: Error Detection and Cyclic Redundancy Check ( CRC ) : Explain the principles of the Cyclic Redundancy Check ( CRC ) method for error detection.

Error Detection and Cyclic Redundancy Check (CRC): Explain the principles of the Cyclic Redundancy Check (CRC) method for error detection. Given a hypothetical data se- quence, describe how the CRC method could identify a single-bit error. Why is CRC commonly used in Ethernet frames?
