1, Host A and Host B are directly connected by a 10 106 bps link. The distance between the two hosts is 1,000 kilometers. Assume that the propagation speed over the link is 2 108 m/s, and that all packets are 125 bytes long. a. What is the propagation delay for a single packet? (4 points) b. What is the transmission delay between the two hosts? (4 points) c. If Host A begins to send a single packet at time t-O, at what time does Host B receive the FIRST bit of the packet? (4 points) LAST bit of the packet? (4 points) packet? (4 points) d. If Host A begins to send a single packet at time t 0, at what time does Host B receive the e. If the packet size is increased to 1 million bytes, what is the propagation delay for a single
