What is a key characteristic of a ring network?

A key characteristic of a ring network is that every node is linked to exactly two other nodes. This configuration creates a closed loop in which data travels in one direction or both directions around the ring, making it efficient for transmitting data between nodes. In this structure, each node acts as a repeater for the data transmitted from one node to the next, facilitating the orderly passing of information throughout the network.

The characteristics of a ring network ensure that each node can receive and send data to its two directly connected neighbors. This setup contrasts with other types of networks, such as star networks, where nodes connect to a central hub, and mesh networks, where nodes can connect to multiple nodes. The design of the ring network has implications for network performance and fault tolerance, as any disconnection or failure of a single node can disrupt the entire network unless additional redundancy measures are implemented.
