Q8. What is token passing?

• A token is small frame, which is passed from one node to another in a token ring network. If a node has data to send, it must wait until it receives a token. After the token is received by the node, it seizes the token, makes it as used, and attaches the data. The frame is then addressed to the destination node and the node continues passing the data around the ring until it arrives at the destination node. The destination node copies the data and marks the frame as received. When the sender node receives the frame, it implies that the data is successfully delivered. The sender node then frees the token to be used by another node.
