HW5

1. Why are Ethernet and Token Ring technologies inappropriate for use in a WAN?
2. How much data can be present on an Ethernet segment at one time? To find out, compute the delay throughput product. An Ethernet operates at 10 megabits per second, and a segment is limited to 500 meters. Assume the signals propagate down the cable at 66 percent of the speed of light (the speed of light is 299,792,458 meters per second).
3. How much data can be "in flight" between a sending ground station, a satellite, and a receiving station? To find out, compute the delay throughput product for a satellite net work that operates at 3 megabits per second (3Mbps). Assume that the satellite orbits at 20,000 miles above the earth, and that radio transmissions propagate at the speed of light.
4. Surf the Internet and find some information on Classless Inter-Domain Routing (CIDR). In a couple of brief paragraphs. state how IP addresses are assigned using CIDR. Include the URL of your information source.

Your homework should be labeled with your name, course number and assignment number.
