In token ring topology, if a host needs to send data, it grabs the token and sends data. Once it receives it again it frees the token. This is what I know about token ring Is token is held by host, while data transmits through the ring or data frame is appended to the token and passed? some websites explain as host holds the token and data passes as frame and once data received by sender , sender frees the token if it completes, but some websites and my lecturer explain that data frame is appended with the token and passed.
How the ring topology works with token? How token looks like?
