Ring Technology is extensively used and utilized in small premises using LAN networks. This network is reliable with fast data accessing and transferring speed.
Due to the significant features of ring topology, they are installed in schools, colleges, and universities campus.
What is Ring Topology in Computer Network
In a ring topology, every node, computer, or device is connected to its neighbor device.
RING TOPOLOGY is used and utilized in LAN [Local Area Network] and WAN [Wide Area Network], where each node is connected in a closed-loop configuration.
The network is directly connected to the device, whereas all the devices are connected through them.
The ring topology is also called “Active Topology”.
In this topology, data, and information are not transferred from one computer to another, but the data is passed or transferred to a device that is next to the device.
In this way, the data and information are given to the computer system.
In a ring topology, all nodes and computers form a ring shape where all nodes are connected.
The signals are passed or transferred with the help of a repeater.
The device attached to the network is called a “Hoop Network” also called “Dual Ring Topology”.
Use these network cards are used for LAN and WAN
This network uses RJ 45 cables and Coaxial cables to connect two computer nodes.

Where is Ring Topology Used?
Ring topology is used in small networks like small offices.
This network cannot work with high-speed data exchange and transfer; also, the size and structure of the network cannot be updated and altered.
In this network, few nodes or devices are attached to the network.
Advantages of Ring Topology
- The data and information rate in a ring topology is higher than in others.
- The network server is not needed for connectivity.
- Other workstations or nodes can be added without disturbing network performance.
- More nodes can be added and modified and can also be removed easily.
- Errors, faults, and bugs are easily detected and resolved with ease.
- Easy to expand the network.
Disadvantages of Ring Topology
- The ring topology can be easily managed.
- Installation is inexpensive.
- If one node is corrupted or damaged affects the entire network.
- The performance of ring topology is comparatively slower than bus topology.
- Removing, moving, and adding nodes affect networks.
- In a unidirectional ring, data passes to all nodes.
Who Invented Ring Topology?
IBM introduced in 1984.
Types of Ring Topology
There are two types of ring topology
- Unidirectional Ring Network.
- Bidirectional Ring Network.
1. Unidirectional Ring
In a unidirectional ring network, the data and information are transferred in one direction, clockwise or anticlockwise.
This network is also called the “Half Duplex Network.”
2. Bidirectional Ring Network
In a Unidirectional ring network, two nodes are connected; hence they are converted into the bidirectional network, also called a “Dual Ring Network”.
Examples of Ring Topology
- The ring topology is used on school, college, and university campuses. The ring topology is used in the small network; data and information are sent from one device to another.
- Optic fiber is used in telephone lines where data and information travel from one device to another in the unidirectional path to all other computers and laptops connected to the network.
- Ring topology is used in LAN and WAN networks.
Different Types of Topology
There are six types of topology in computer networks
- Bus Topology.
- Ring Topology.
- Star Topology.
- Mesh Topology.
- Tree Topology.
- Hybrid Topology.
Applications of Ring Topology in Tabular Form
- The ring topology is used in small premises like schools, colleges, and universities.
- The ring topology works faster and presents a higher data transfer rate.
- The data and information is transferred in a unidirectional path.
- WAN [Wide Area Network] also with ring topology as WAN is a collection of LANs.
- Optical Network (SONET) is used for a big telephone call through fiber optic cables.
Three Limitations of Ring Topology?
- Single Point of Failure.
- Limited Scalability.
- Performance Impact.
