A token is a unique frame that is approved from node to node about a ring system, it is a sequence of bits passed continuously between nodes in a fixed order and enables a node to transmit information. When it gets to a node that requires transmitting data, the node modifies the token into a data frame and transfers it to the receiver. A token is fundamental to the internal workings of a token ring network.
