A. Calculate the checksum of following 2 bytes: 00110101 and 10101100, and fill in the blank: Checksum: B. Calculate the checksum of following 2 bytes: 01011010 and 10110100, and fill in the blank: Checksum: Note: fill in binary numbers only. In the simple TCP client/server socket programming experiment, the client sends a word 'network' (total 8 bytes, including carriage return), and the server echoes with 'NETWORK', as shown in the figure below. Assume the client has a SendBase of 50, and the server has a SendBase of 90. Client Server Client SendBase Client enters the word A. Seq-A: B. ACK-B: C. Seq-C:: D. ACK-D: Please calculate the sequence numbers A-F for the above figure and fill in the spaces below: E. Seq-E: Seq=A, ACK=B, data F. ACK-F: Seq=C, ACK=D, data Seq=E, ACK=F Server SendBase Server receives, ACKS echoes capital word
