Consider a 20,000,000-character message to be transmitted between two stations that are 150 meters apart, using a 10BaseTX LAN with a transmission speed of 50 meters per microsecond (50m/ms).
The packet size is 768 bits, of which 80 is overhead.
Each packet is acknowledged with an additional 88 bits.
a. What is the effective throughput of this LAN?
b. What would be the effective throughput if the network were upgraded to gigabit Ethernet?
