WHAT IS RING TOPOLOGY ?

Ring Topology is where each node connects exactly to two other nodes, forming a single continuous pathway for signals through each node in a ring. This section will analyze the advantages, disadvantages, and misconceptions of the ring topology.

Advantages

• Data is quickly transferred without a ‘bottle neck’. (very fast, all data traffic is in the same direction)
• The transmission of data is relatively simple as packets travel in one direction only.
• Adding additional nodes has very little impact on bandwidth
• It prevents network collisions because of the media access method or architecture required.

Disadvantages

• Data packets must pass through every computer between the sender and recipient therefore this makes it slower.
• If any of the nodes fail then the ring is broken and data cannot be transmitted successfully.
• It is difficult to troubleshoot the ring.
• Because all stations are wired together, to add a station you must shut down the network temporarily.
• In order for all computers to communicate with each other, all computers must be turned on.
• Total dependence upon the one cable
