This is different from a local printer that is directly connect to the computer via USB cable.
Network printer is very advantageous in that multiple network computers can access the printer at thesame time.
Answer:
In a STAR TOPOLOGY network, each device on the network is attached to a central router. If the router fails, then the other devices will be unable to communicate, but if only one connected device fails, then all other devices will still be able to communicate.
Explanation:
In this type of topology all the computers are connected to a single router through a cable. This router is the central node and all others nodes are connected to the central node.
