2. Recall that data correction protocols based on retransmissions are known as ARQ protocols (Automatic Repeat reQuest). Assume a Stop-and-Wait ARQ system, the bandwidth of the link between sender and receiver is 1 Mbps and 1 bit takes 20 msec to make a round trip. a. If the system data segments are 1,000 bits in length, what is the utilization of a noise-free link? b. If we use a protocol that can send up to 15 segments before stopping and worrying about the acknowledgments, what is the utilization of a noise-free link
