RING TOPOLOGY

Also known as a ring network, the ring topology is a type of computer network configuration where each network computer and device are connected to each other forming a large circle (or similar shape). Each packet is sent around the ring until it reaches its final destination. Today, the ring topology is seldom used.


Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A node failure or cable break might isolate every node attached to the ring.

Advantages

• Very orderly network where every device has access to the token and the opportunity to transmit
• Performs better than a star topology under heavy network load
• Can create much larger network using Token Ring
• Does not require network server to manage the connectivity between the computers

Disadvantages

• One malfunctioning workstation  can create problems for the entire network
• Moves, adds and changes of devices can affect the network
• Network adapter cards is much more expensive than Ethernet cards and hubs
• Much slower than an Ethernet network under normal load
