without affecting any
other node on the network. Its weakness, however, is that failure of the central
computer results in a shutdown of the entire network. And because each node is
individually wired to the hub, cabling costs can be high.Ring networkRing
Network, in computer science, a local area network in which devices (nodes) are
connected in a closed loop, or ring. Messages in a ring network pass in one
direction, from node to node. As a message travels around the ring, each node
examines the destination address attached to the message. If the address is the
same as the address assigned to the node, the node accepts the message;
otherwise, it regenerates the signal and passes the message along to the next
node in the circle. Such regeneration allows a ring network to cover larger
distances than star and bus networks. It can also be designed to bypass any
malfunctioning or failed node. Because of the closed loop, however, new nodes
can be difficult to add. A ring network is ...
