Ring topology in networking forms a structure of Ring in the network formation. all the nodes are connected na ring and data travels in one direction using a control signal called a token.
Each node connects to exactly two other nodes, forming a single continuous pathways for signals through each node as a ring.
Data travels from one node to another, with the each node by handling all the packet and acknowleding them.

Advantages of Ring Topology
- Not affected by adding further nodes or heavy network traffic as only the node with the token can transmit data so there are no data collisions.
- Relatively cheap to install and expand.
Disadvantages of Ring Topology
- It is very slower than the star topology while it is on the normal node.
- If the cable fails at any point in the ring then the whole network will fail to work or act.
- If any node fails then the token cannot be passed around the ring any longer so the whole network fails.
- The hardest topology to troubleshoot is that it can be hard to track down where the failure has occurred in the ring.
- Harder to modify or expand because by adding or removing a node you must shut down the network temporarily.
- In order for the nodes to communicate with each other, they must all be switched on.
