a) Consider that a host is sending a frame of 1200 bytes to another host found 20 Kilometers away. (Assume that switching delay is negligible)
i) Calculate the total latency (from the first bit transmitted by sending host to the last bit buffered by receiving host) on a 100Base-FX Ethernet network with a "store-and-forward" switch in the path. Assume that the link introduces a propagation delay of 2 x 108m/s and that the switch begins retransmitting immediately after it has finished buffering the frame completely.
ii) Same as (i) but assume that the switch implements "cut-through": it is able to begin retransmitting the frame as soon as the first 100 bits have been buffered.
iii) Give a suitable type of transmission media that can be used for this communication.
