This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider two hosts, A and B, connected by a single link. A is to send a packet to B. Assume dtrans and dprop represent transmission and propagation delay.

a. Suppose Host A begins to transmit the packet at time t = 0. At time t = dtrans, where is the last bit of the packet and why?

b. Suppose dprop > dtrans. At time t = dtrans, where is the first bit of the packet and why? c. Suppose dprop
