Q1) UDP and TCP use 1s complement their checksums. Assume you have following three 8-bit bytes: 01010011, 01010100, 01110100. Determine the 1s complement of sum of these eight-bit bytes? (Note that although UDP and TCP you 16-bit words in computing the checksum, for this problem you are being asked to consider 8-bit sums.) Show all work. Why is it that UDP takes the 1s complement of the sum; that is, why not just use the sum? With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
