3.4. Ring Topology

A ring topology is really not a physical course of action of a network link, as you may figure. Rather, rings are a consistent course of action; the real links are cabled in a star, with every node associated all alone link to the MAU. Be that as it may, electrically, the network carries on like a ring, where the network signals move around the ring to every node thus. Figure 3.4 demonstrates a example ring topology network.

Ring topology LANs depend on Token Ring rather than Ethernet. Some may likewise run Fibre Distributed Data Interface (FDDI)— a 100 Mbps fibre optic network—rather than copper based link. Rings are likewise utilized for some bigger telecommunications networks like Synchronous Optical Network (SONET), and also storage area networks and some different apps.

You'll frequently listen to the terms physical and logical bandied about when talking about networks. These terms are utilized for many diverse things. Physical, utilized in the perspective of networking, means the real, physical thing—what you can observe and sense. Logical means how it functions, regardless of its look. For instance, a Token Ring network is physically cabled in a star; every link transmits out from the MAU to every node. Coherently, however, it's a ring in which the signals make a trip from node to node in a round manner. The way that the signals physically make a trip from the node to the MAU and back to the following node is typically immaterial when pondering the coherent round course of action of the Token Ring network.
