1. If one pings IP address 127.0.0.1, the latency is extremely low. Explain.

2. Use ping to measure network latency to local and distant sites. What is the minimum and maximum Internet delay measured?

3. Compare the throughput of a 100 Mbps network and a 1 Gbps network.

4. Download a copy of the program ttcp, and use it to measure throughput on a local Ethernet. What is the goodput? Estimate the link utilization achieved.
