because the data does not pass through every node.
For Example High-Speed LAN, etc.
Following are the advantages of Star topology:
Following are the advantages of Star topology:
Centralized control.
Less Expensive.
Easy to troubleshoot(the faulty node does not give response).
Good fault tolerance due to centralized control on nodes.
Easy to scale(nodes can be added or removed to the network easily).
If a node fails, it will not affect other nodes.
Easy to reconfigure and upgrade(configured using a central device).
Following are the disadvantages of Star topology:
If the central device fails, the network will fail.
The number of devices in the network is limited(due to limited input-output port in a central device).
Mesh Topology
Mesh topology is a computer network topology in which nodes are interconnected with each other. In other words, direct communication takes place between the nodes in the network.
Hybrid Topology:
Hybrid Topology:
A Hybrid topology is a computer topology which is a combination of two or more topologies. In practical use, they are the most widely used.
In this topology, all topologies are interconnected according to the needs to form a hybrid. All the good features of each topology can be used to make an efficient hybrid topology.
Following are the advantages of Hybrid topology:
It can handle a large volume of nodes.
It provides flexibility to modify the network according to our needs.
Very Reliable(if one node fails it will not affect the whole network).
Following are the disadvantages of Hybrid topology:
Complex design.
Expensive to implement.
Multi-Station Access Unit(MSAL) required.
Hence, after learning the various computer network topologies, we can conclude that some points need to be considered when selecting a physical topology:
