Advantages and Disadvantages of Different Network Topologies
Network topologies describe the ways in which the elements of a network are connected.
They describe the physical and logical arrangement of network nodes
Advantages and Disadvantages of...
▸ The data being transmitted between two nodes passes through all the intermediate nodes. A central server is not required for the management of this topology.
▸ The traffic is unidirectional and the data transmission is high-speed.
▸ In comparison to a bus, a ring is better at handling load.
▸ The adding or removing of network nodes is easy, as the process requires changing only two connections.
▸ The configuration makes it easy to identify faults in network nodes.
▸ In this topology, each node has the opportunity to transmit data. Thus, it is a very organized network topology.
▸ It is less costly than a star topology.
▸ The failure of a single node in the network can cause the entire network to fail.
▸ The movement or changes made to network nodes affect the entire network's performance.
▸ Data sent from one node to another has to pass through all the intermediate nodes. This makes the transmission slower in comparison to that in a star topology. The transmission speed drops with an increase in the number of nodes.
▸ There is heavy dependency on the wire connecting the network nodes in the ring.
