Ethernet Topology

In a ring topology, each device has exactly two neighbors for purposes of communication. All messages traveling through a ring in the same direction (either to the right or left). A fault in any wiring or circuit device breaks to knock down the entire network. A topology in ring unlike a network star provides only one path between two nodes, in ring networks can be interrupted by the failure of a single link. An error of node or the cable could break isolate every node connected to the ring.

FDDI networks overcome this vulnerability by sending data on a timer on the ring: in the case of a data breakpoint is wrapped back into the ring, it is a complementary measure until it reaches the end of the cable, maintenance routed to each node along the network known as C – Ring. Ring network topology is very similar to the bus network since it is based as a complex work unit in which the whole system are subject to the same errors and become depedientes from each other. These are some of the advantages and disadvantages offered by the network ring. Advantages: * is a very orderly network where every device has access to the signal and the same opportunity to transmit. * It is better acting than a bus network topology since it is not so heavy. You can create a much larger network using Token Ring. ** Not required network server to manage connectivity between computers disadvantages: * If a workstation is malfunctioning or the port in the MAU can create problems for the entire network. * Some additions and changes of devices can affect the network. * MAU and network adapter cards are much more expensive than Ethernet cards. * Much slower than an Ethernet network under normal activity.
