Final answer:
In networking, a token is a special empty data packet that circulates in a token ring network, allowing devices to take turns sending data.
Step-by-step explanation:
A token in the context of networking is an empty packet of data on a network that is used in token ring networks to manage the permissions to send data between nodes. It is not a type of cable nor is it a server. Instead, it functions as a sort of 'pass' that allows devices to take turns communicating over the network. When a device receives the token, it can send data; otherwise, it must wait for the token to become available.
