Which error detection method uses one’s complement arithmetic?(a) Si

1.	Which error detection method uses one’s complement arithmetic?(a) Simple parity check(b) Two-dimensional parity check(c) CRC(d) ChecksumI have been asked this question in an interview for internship.I'd like to ask this question from Parity Generators/Checkers in portion Combinational Circuits of Digital Circuits
Answer» The correct option is (d) Checksum Easiest explanation: A checksum is an error DETECTION method used for the purpose of detecting errors that may have been incorporated during transmission. The checksum can be GENERATED simply by adding BITS. HENCE, ONE’s complement arithmetic uses checksum.
