LANs: Introduction to Ethernet

1. Discuss factors that limit speed of operation and range in cables.
2. Discuss the techniques used to enable Ethernet to operate at speeds of 100 Mbps, or more.
3. Consider the transfer of a million bytes of data from one station to another, distance D apart, by means of encapsulation. What is the total elapsed time and effective throughput for the following cases:

a. A circuit-switched, star topology local network. Call set-up time is negligible and the data rate is 64 kbps.
b. An Ethernet network transmitting data at a rate of 10 Mbps. The propagation speed is 200m/ms.
c. An Ethernet network transmitting data at a rate of 100 Mbps. The propagation speed is 200m/ms.

Where D is:
