Which technique is used to detect errors in Ethernet frames?

Options

  • A. Parity Check
  • B. Cyclic Redundancy Check (CRC)
  • C. Hamming Code
  • D. Checksum only
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. Cyclic Redundancy Check (CRC)

Detailed Explanation

Correct Answer: Cyclic Redundancy Check (CRC)

  • Ethernet uses CRC-32 for frame error detection.
  • The Frame Check Sequence (FCS) field contains the CRC value.
  • The receiver checks the frame for transmission errors.
  • CRC detects errors but does not itself correct them.
