Multiple choice

Which error detection method uses one's complement arithmetic?

  1. Simply parity check

  2. Checksum

  3. Two-dimensional parity check

  4. CRC

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Checksum is the error detection method that uses one's complement arithmetic to detect data transmission errors. It sums data values and uses one's complement for overflow handling. Parity checks use single bits, CRC uses polynomial division, and 2D parity adds a second dimension.
