4) Consider the Rdt 2.0 protocol for reliable data transfer. Given the data (actual payload) determine checksums at sender and receiver side. Also, determine what type of response will be sent from receiver to sender. Explain? (20 points) Give values for sender checksum, receiver checksum and response? Response = ? Sender Unreliable channel bit error Receiver Data (payload) = (1100 1010, 0101 1100) Received Data (payload) = (1101 1010, 1010 1100) Checksum = ? Checksum =
