Describe a problem with an Ethernet hub that using an Ethernet switch solves.
What will be an ideal response?
The problem with an Ethernet hub that replacing it with an Ethernet switch solves is that on a hub the total speed of the network is 10 Mbps, and only one conversation can take place at a time. Therefore, when more than two computers wish to communicate, it reduces the effective bandwidth of each conversation. A switch solves this problem, because, rather than send all incoming frames out all the other ports (as a hub does), a switch only sends signals to the destination port. Therefore, each conversation gets the entire 10-Mbps bandwidth.
