Assume that, in a stop-and-wait ARQ system, the bandwidth of the data line is 1Mbps, and 1 bit takes 20 ms to make a round trip. Find the bandwidth-delay product and the utilization percentage of the link respectively if the system data frames are 1000 bits in length.
1
20,000 bits, 5%
2
10,000 bits, 10%
3
5,000 bits, 20%
4
40,000 bits, 2.5%
