UDP and TCP use bits complement to generate checksums. Assume you have the following three 8-bit bytes: 01010111, 01010110, 01110110. What are the complement of the bit of the sum of these 8-bit bytes? Show all steps. Why are bits that UDP takes the complement of the sum; why not just use the sum? With this complement scheme, how does the receiver detect errors? Is it possible that a 1-bit error will go undetected? How about a 2-bits or more error?
