Signalling and communicationQuestion 142 of 1506

In a token-passing protocol, what is the token?

  1. Binary bits sent on the network that carry the address of the next node to talk
  2. A physical ring that is handed from one node to the next node in turn
  3. A fuse that is fitted in each node to stop two talking
  4. A cable connector that links the nodes into a ring
Show answer

Correct answer: Binary bits sent on the network that carry the address of the next node to talk

The token is not a physical thing.
