4. A computer network runs at 1 gigabit per second. Data is sent in packets on the network; each packet contains 1500 bytes (a byte is 8 bits). Each packet is transmitted at line speed (1 gigabit per second). However, the network controller also requires 10 s of overhead for each packet, during which time it can't transmit any data. (a) [2 points] What is the latency to send a single packet? Remember, this consists of the overhead and the time to actually send the data, which can't be overlapped. (b) [2 points] What is the actual throughput of the network, including the overheads listed above, in packets per second? What is the throughput in bits per second? (c) [2 points] What fraction of the network's time is "wasted" due to the controller's overhead?
