In computer networking, topology is the arrangement of devices and their connections. Ring topology is a type of network configuration in which each device on the network is connected to two other devices, forming a “ring.” Data travels around the ring in one direction only, from device to device, until it reaches its destination.

What is Ring Topology?
In computer networking, a ring topology is a network configuration in which each node is connected to two other nodes in the network, building a single continuous pathway for signals through the network. Ring topologies are often used in local area networks (LANs).
In a ring topology, each node has two neighbours, with the signals travelling in opposite directions around the ring. If one node fails, the network can reroute signals around the failed node using the other nodes as alternate paths. This redundancy can improve reliability and fault tolerance, but it also adds complexity to the network.
Ring topologies can be designed using either twisted pair cable or fibre optic cable. The choice of cable type will depend on the distance between nodes, the data transfer speed required, and other factors.
Advantages of Ring Topology
- One major advantage is that it is very difficult for an outsider to tap into or interfere with a network using this type of configuration.
- Additionally, if one node on the network goes down, the rest of the nodes can continue to communicate with each other without issue. This can be a big advantage in mission-critical situations where uptime is key.
- Finally, ring topologies tend to be very easy to expand and add new nodes to as needed.
Disadvantages of Ring Topology
There are a few disadvantages to ring topology.
- First, if one node fails, the entire network fails.
- Second, adding or removing a node from the network can be difficult.
- Third, ring topologies are not well suited for large networks.
- Finally, they are susceptible to broadcast storms.
