It is called a Star topology
A star topology has a central hub with other devices each connected to the hub but not to each other - for one device to communicate to another, they have to use the hub. With a bus topology all the devices are connected to the same bus - there is no hub. Each topology has advantages and disadvantages; the speed of a star network is limited by the hub; a telephone exchange is an example of a star network and there is a built-in limit to the number of devices that can be connected and there's no way to increase it other than to replace the hub with a bigger one. However, the devices (telephones in our example) can be dumb - all the intelligence is in the hub; it manages the calls and importantly, for commercial exchanges, calculates the bills. For bus networks, devices have to be smarter but can do much more as they can grab the whole bus.
In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.
Ring topology
Mesh Topology
star topology
The arrangement of computers on a network is called topology. It describes how the individual computers are connected to each other and to the network.examples of topology are Star topology, ring topology, mesh topology, bus topology.
It is called a Star topology
The computer term 'mesh topology' is where a group of computers are connected to a network interconnecting with each other, thereby allowing the transmission to be distributed between all the connected computers.
in bus topology computers are connected with each other by a wire in a approximately strait manner..and if one computer stops working the whole network will stop. while in star topology every computer is connected with the host computer & much wire is require..and if any client computer tops working it will not effect the whole network.----ravi singh chauhan...7275974787

Ring technology: In a ring network, every device has exactly two neighboring devices for communication purpose. It is called a ring topology as its formation is like a ring. In this topology, every computer is connected to another computer. Here, the last node is combined with a first one. This topology uses token to pass the information from one computer to another. In this topology, all the messages travel through a ring in the same direction.
