Where the ring topology is commonly used?

Ring topology is commonly used in local area networks (LANs), particularly in environments that require predictable performance, such as in schools and small businesses. It was historically prevalent in token ring networks, where data packets travel in a unidirectional or bidirectional manner around the ring, minimizing collisions. Although less common today due to the rise of star and mesh topologies, ring topology can still be found in certain industrial applications and metro area networks (MANs). Its structured layout allows for easier troubleshooting and management of network traffic.
