Q2 Suppose two hosts A and B, are separated by d-20,000 km and are connected by a link R -2Mbps (2 x 106 bps). Assume that the propagation speed s 2.5 x 108 m/s, 1. What is the unit? Calculate the bandwidth-delay product, i.e., Rx propagation delay. 2. Consider sending a file of L-800,000 bits from A to B. If the file is sent continuously as one large message, what is the maximum number of bits that will be in the link at any given time
