Refer to the exhibit. If the hubs in the graphic were replaced by switches, what would be virtually eliminated?
正解:C
Explanation/Reference: Explanation: Modern wired networks use a network switch to eliminate collisions. By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half duplex links) or the possibility of collisions is eliminated entirely in the case of full duplex links.
