Token Ring is a type of network topology that uses a ring-shaped physical topology and a logical ring topology to transmit data between devices. In a Token Ring network, devices are connected in a circular fashion, with each device connected to the next device in the ring.
Data is transmitted in the form of a token, which is a special packet that circulates around the ring. When a device wants to transmit data, it waits until it receives the token, which gives it permission to transmit. The device then adds its data to the token and sends it around the ring until it reaches its destination.
