In CRC, if the dataword is 5 bits and the codeword is 8 bits, how many 0s need to be added to the dataword to make the dividend? What is the size of the remainder? What is the size of the divisor?

In CRC, which of the following generators (divisors) guarantees the detection of an odd number of errors?

a. 10111 b. 101101 c. 111

Assume we are sending data items of 16-bit length. If two data items are swapped during transmission, can the traditional checksum detect this error? Explain your answer.
