What is a ring bus also known as?

A ring bus is commonly referred to as a closed loop system because it forms a continuous pathway for data transmission, allowing for a consistent and reliable flow of information. In this configuration, each device on the network is connected to two other devices, forming a ring topology. This structure enables data to circulate in one direction, which helps maintain the integrity of the network even if a single connection is disrupted, as the remaining connections can still facilitate data flow.

This characteristic of maintaining connectivity in a dedicated loop is what distinguishes it from open systems or other arrangements like direct connection systems, where data paths can be more fragmented, and the overall network can face issues if a direct link fails. The closed loop nature of the ring bus system enhances error detection and improves fault tolerance, making it an effective choice for many networking applications.
