b) Consider an Ethernet hub with 8 ports and an Ethernet switch with 8 ports. In both cases (hub and switch), each port is rated at 100 Mbps. Assume that you use either the hub or the switch to create a small home network of 8 hosts. Which of the two networks (hub-based or switch-based) will be able to achieve a greater total network throughput (the total throughput is defined here as the sum of individual throughputs over all simultaneous communications between the hosts connected to the network)? Why?
