A. Hamming code
B. Checksum
C. Parity check
D. Cyclic redundancy check
Explanation: Given all codes are error detecting codes other than hamming code. Error detecting codes are used for noisy and wireless links whereas error correcting codes are used for channels like optical fiber.
A. Fletcher’s checksum
B. Polynomial code
C. Generator polynomial code
D. Checksum
Explanation: Polynomial codes has the polynomial representation for bit strings and these polynomials have 0 or 1 as their coefficients. It makes use of generator polynomial to do further calculation in finding errors.
