What is ring topology?

Answer 1

the ring topology is a network within which all computer are connected like in a circle. The ring topology data transmission is depending on a token. it's a programme given to a computer to allow it to communicate with others computers. it's useful but if one computer goes down, the topology is down too.

Answer 2

A network topology in which two concentric rings connect each node on a network instead of one network ring that is used in a ring topology. Typically, the secondary ring in a dual-ring topology is redundant. It is used as a backup in case the primary ring fails. In these configurations, data moves in opposite directions around the rings. Each ring is independent of the other until the primary ring fails and the two rings are connected to continue the flow of data traffic.

A network topology that employs two rings for the purpose of redundancy. If one ring experiences a failure, the other provides operability.

Dual-ring topology is a network redundant topology where nodes are connected using two concentric rings with four branches. Dual-ring topology is ideal for applications with cabling issues or small networks that are not frequently reconfigured.

Though more expensive than star or extended star topologies, dual-ring is the most cost-efficient redundant topology.

Dual-ring topology is made up of two rings connected to a network. Each ring works independently until one is disabled when the network fails. When this takes place, the functioning ring automatically wraps around the disabled ring to ensure data flow.

Ring topology advantages include:

• Speed and reliability

• Uninterrupted long distance communication

• Terminators are not required

Ring topology disadvantages include:

• Network issues from bad ports or malfunctioning Media Access Unit (MAU) cards

• Negative network impact from any added,altered or damaged device
