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, only one token can pass through the network at a time. This token-passing method ensures that only one device can send data at any given moment, preventing collisions. Therefore, only one token is present in the ring network simultaneously.
Nobody knows......
I assume you're talking about a network. On a token network, all of the computers wait to send data until they have the token. The token is a piece of data that travels around the network (picture all of the computers set up in a circle) giving each one a chance to send their data. After that computer has sent the data, the token moves on to the next. It prevents data collision on the network.
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.
In a ring topology, the access method used is typically token passing. In this method, a token is passed around the ring from one node to the next, allowing nodes to transmit data when they possess the token. This helps in controlling and managing the network traffic in a structured manner.

ri
In networking, a token passing topology is a method where a special data packet, called a token, circulates around the network. Only the device that holds the token can send data, ensuring organized access and reducing collisions. This approach enhances network efficiency and reliability by controlling the flow of data between devices. Examples of token-based protocols include Token Ring and Token Bus.

token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical ring.
