Suppose a 10-Mbps Ethernet hub (repeater) is replaced by a 10-Mbps switch, in an environment where all traffic is between a single server and N "clients." Because all traffic must still traverse the server-switch link, nominally there is no improvement in bandwidth.
(a) Would you expect any improvement in bandwidth? If so, why?
(b) What would your answer be if the original hub were token ring rather than Ethernet?
(c) What other advantages and drawbacks might a switch offer versus a hub?
