Checksum (10 points). UDP and TCP use ls complement for their

Checksum (10 points). UDP and TCP use ls complement for their checksums. Suppose you have the following three 8-bit sequences: 01010101, 01110000, 01001100. What is the checksum over the three bit sequences? (Note that although UDP and TCP use 16-bit words in computing the checksum, in this problem, for simplicity, we consider 8-bit summands.) Show all work. How does the receiver detect errors using checksum? Is it possible that a 1-bit error will go undetected? How about a two-bit error
