3. [6 marks) UDP and TCP use 1s complement for their checksums. Suppose you have the following three 8-bit bytes: 01010010, 01100110, 01110110. (Note that although UDP and TCP use 16-bit words in computing the checksum, for this problem you are being asked to consider 8-bit sums.) a) With the 1s complement scheme, how does the receiver detect errors? b) What is the 1s complement of the sum of these 8-bit bytes? Show your work step by step
