Which error detection technique uses polynomial division?

Options

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

Correct Answer (Detailed Explanation is Below)

C. Cyclic Redundancy Check (CRC)

Detailed Explanation

Correct Answer: (C) Cyclic Redundancy Check (CRC)
CRC uses modulo-2 polynomial division to generate a remainder. The remainder is appended to the data and checked by the receiver to detect transmission errors.
