Question

Write the advantage and disadvantage of the following ring topology ,bus topology,and mesh topology

Answer 1

Explanation:

Bus Topology

Advantages of Bus Topology

• It is easy to set up, handle, and implement.

• It is best-suited for small networks.

• It costs very less.

Disadvantages of Bus Topology 

• The cable length is limited. This limits the number of network nodes that can be connected.
• This network topology can perform well only for a limited number of nodes. When the number of devices connected to the bus increases, the efficiency decreases.

• It is suitable for networks with low traffic. High traffic increases load on the bus, and the network efficiency drops.

• It is heavily dependent on the central bus. A fault in the bus leads to network failure.

• It is not easy to isolate faults in the network nodes.

Ring Topology

Advantages of Ring Topology

• 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.

Disadvantages of Ring 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.

Mesh Topology

Advantages of Mesh Topology

• The arrangement of the network nodes is such that it is possible to transmit data from one node to many other nodes at the same time.

• The failure of a single node does not cause the entire network to fail as there are alternate paths for data transmission.

• It can handle heavy traffic, as there are dedicated paths between any two network nodes.

• Point-to-point contact between every pair of nodes, makes it easy to identify faults.

Disadvantages of Mesh Topology

• The arrangement wherein every network node is connected to every other node of the network, many connections serve no major purpose. This leads to redundancy of many network connections.

• A lot of cabling is required. Thus, the costs incurred in setup and maintenance are high.

• Owing to its complexity, the administration of a mesh network is difficult.
