It is cost effective.
Cable required is least compared to other network topology.
Used in small networks.
It is easy to understand.
Easy to expand joining two cables together.
It transmits data only in one direction.
Every device is connected to a single cable .
Cables fails then whole network fails.
If network traffic is heavy or nodes are more the performance of the network decreases.
Cable has a limited length.
It is slower than the ring topology.
Partial Mesh Topology : In this topology some of the systems are connected in the same fashion as mesh topology but some devices are only connected to two or three devices.
Full Mesh Topology : Each and every nodes or devices are connected to each other.
Each connection can carry its own data load.
It is robust.
Fault is diagnosed easily.
Provides security and privacy.
Fully connected.
Robust.
Not flexible.
Installation and configuration is difficult.
Cabling cost is more.
Bulk wiring is required.
A number of repeaters are used for Ring topology with large number of nodes
The transmission is unidirectional,it is called Dual Ring Topology.
Data is transferred in a sequential manner that is bit by bit
Transmitting network is not affected by high traffic or by adding more nodes, as only the nodes having tokens can transmit data.
Cheap to install and expand
Troubleshooting is difficult in ring topology.
Adding or deleting the computers disturbs the network activity.
Failure of one computer disturbs the whole network.
Every node has its own dedicated connection to the hub.
Hub acts as a repeater for data flow.
Can be used with twisted pair, Optical Fibre or coaxial cable.
Fast performance with few nodes and low network traffic.
Hub can be upgraded easily.
Easy to troubleshoot.
Easy to setup and modify.
Only that node is affected which has failed, rest of the nodes can work smoothly.
Cost of installation is high.
Expensive to use.
If the hub fails then the whole network is stopped because all the nodes depend on the hub.
Performance is based on the hub that is it depends on its capacity
Ideal if workstations are located in groups.
Used in Wide Area Network.
Extension of bus and star topologies.
Expansion of nodes is possible and easy.
Easily managed and maintained.
Error detection is easily done.
Heavily cabled.
Costly.
If more nodes are added maintenance is difficult.
Central hub fails, network fails.
It is a combination of two or topologies
Inherits the advantages and disadvantages of the topologies included
Reliable as Error detecting and trouble shooting is easy.
Effective.
Scalable as size can be increased easily.
Flexible.
Complex in design.
