Defination:

• Computers and devices are connected to a closed loop cable. Here there are no terminating ends so if one system crashes the entire network goes down.
• Each computer functions as a repeater and charges the signal before sending it to the next station.

Points:

• Meaning that data travels in circular fashion from one computer to another on the network.
• Typically FDDI, SONET or Token Ring technology are used to implement a ring network
• Ring networks are most commonly wired in a star configuration

Advantages:

• Cable faults are easily located, making troubleshooting easier
• Ring networks are moderately easy to install

Disadvantages:

• Expansion to the network can cause network disruption
• A single break in the cable can disrupt the entire network.
