Star network.
Here Central server route data between clients.
In a star topology, a central server [or switching hub] switches data around the network. Data traffic between nodes and the server will thus be relatively low.
Merits.
Since the data rate is relatively low between central server and the node, a low specification twisted-pair cable can be used to connect the nodes to the server.
A fault on one of the nodes will not affect the rest of the network. Typically, mainframe computers use a central server with terminals connected to it.
Disadvantage.
The network is highly dependent upon the operation of the central server. If it were to slow significantly then the network becomes slow. And if it were to become un-operation then the complete network would be shut down.
