Question 5 (2points): You are the designer of a transfer protocol to send/receive a file between two computers. The sender divides the file into smaller frames to be sent sequentially to the receiver, and there are two options to make sure that receiver receives the file correctly: The sender can send frame n+1 if receives an ACK on frame n from the receiver (e.g., sender receives ACK on frame 2, so will proceed and send frame 3). The sender sends all the frames sequentially and the receiver will send only one ACK if the entire file is received successfully. Which approach, from your point of view, is efficient and why - If we have: 1) noisy communication channel (there is high probability of more than one device speak at the same time, high probability of interference). II) non-noisy communication channel
