In ring topology, the computer that is allowed to transmit data possesses the ________

In ring topology, the computer that is allowed to transmit data possesses the "Token". A token is a small data packet that circulates around the network in a specific order. When a computer wants to transmit data, it must wait until it receives the token. Once the computer receives the token, it can transmit data onto the network, and the token will move on to the next computer in the ring. In this way, the token acts as a way to control access to the network and prevent multiple computers from transmitting data at the same time, which could cause collisions and data loss.
