The Token Ring topology uses token passing as an access method. In this network configuration, a token, which is a small data packet, circulates around the network nodes, granting permission to the device holding it to transmit data. This method helps to prevent collisions and ensures orderly access to the network medium. Token passing can also be found in other protocols like Token Bus and Fiber Distributed Data Interface (FDDI).
In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.
star topology,bus topology,ring topology,mesh topology etc...
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.

How does Token Bus (IEEE 802.4) enforce discipline on a logical ring topology? ----
An old topology called Token Ring
Token Ring is an active topology - each packet must be recreated as it goes from client to client.
Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
You are thinking ring topology. Not used much today.
