Advantages and disadvantages
This type of network topology is very organized. Each node gets to send the data when it receives an empty token. This helps to reduces chances of collision. Also in ring topology all the traffic flows in only one direction at very high speed.
Even when the load on the network increases, its performance is better than that of Bus topology.
There is no need for network server to control the connectivity between workstations.
Additional components do not affect the performance of network.
Each computer has equal access to resources.
Each packet of data must pass through all the computers between source and destination. This makes it slower than star topology.
If one workstation or port goes down, the entire network gets affected.
Network is highly dependent on the wire which connects different components.
MAU’s and network cards are expensive as compared to Ethernet cards and hubs.
What is a ring topology?
In Ring Topology, all the nodes are connected to each-other in such a way that they make a closed loop. Each workstation is connected to two other components on either side, and it communicates with these two adjacent neighbours. Data travels around the network, in one direction. Sending and receiving of data takes place by the help of TOKEN.
