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.
In reg-mem architecture, clock cycle is 10 ns wide. It is proposed that reg-reg architecture be used instead, that reduces the clock cycle by 2 ns. However, it requires an addition
Large data packets result in fewer load because a smaller part of the packet is used for header information. Optimum networks use 4kB data packets or larger. Large data packets

What is the full form of FDM and TDM It is both. Each of the 100 channels is possess its own frequency band (FDM), and on every channel two logical streams are intermixed by th
What is the difference between routable and non- routable protocols? Ans) Routable protocols can work with a router and can be used to build huge networks. Non-Routable protocol
Repeaters - Operate only in physical layer - Connects two segments of the same LAN - Both segments must be of the same protocol - Only forwards frames; does not filter
