Which of the following best describes a token ring network?

A token ring network is best described as a circular network topology that uses a token-passing mechanism for data transmission. In this type of network, each device (or node) is connected to a circular path, and data packets can only be sent when a device possesses a special data packet known as a token. The token is passed around the network, allowing nodes to take turns transmitting data, which helps to manage access to the shared communication medium and prevents data collisions.

This structure effectively means that only the device holding the token can send data, ensuring organized and regulated communication within the network. It highlights the importance of control and efficiency in data transmission, distinguishing token ring networks from other configurations like bus or star topologies, where devices may have different methods of accessing the medium.
