RING TOPOLOGY

DEFINITION.

Ring topology is a each network computer and device are connected to each other forming a large circle or similar shape.example of a simple setup on a network using a ring topology.

WHAT IS RING TOPOLOGY.

The logical ring topology is another important topology in LAN Connectivity . As the name implies, host are connected in the form of a ring or circle . Unlike the physicalbus topology . A frame travels around the ring , stopping are each node. If a node wants to transmit data, it is permitted to add that data as well as the destinationaddress to the frame . The frame then continues around the ring until it finds the destination node , which takes the data out of the frame. The advantage of using this type of method is that there are not collisions of data packets. two types of rings exists.

HOW RING TOPOLOGY WORKS.

A ring topology is a networking method in which the hubs are all interconnected in a circle. Think of it like a compass rose where the directions are computers. They can all communicate with each other, but for north to talk to south, it must go thru west or east first, and the same for west to east, they must go thru the prior. The major problem with the ring topology is that if one crashes then they all do. You see thesignal in a ring system only flows in one direction (kinda like ethernet) so if north ruptures the line and the signal travels clockwise east could send to all computers on the network, including north(even tho its broke) however it could not receive signals from anybody, North is blocking the ring and the signal travels clockwise so if west was trying to talk to south, the hub closest to it, it couldnt even do it. This is why in most cases network technicians will use the home run (star) topology, because each computer is responsible for itself, and not half the network.
