Which topology must a token-passing protocol use?

  1. Only the ring topology, because the token must follow the ring
  2. It is not limited to any particular topology
  3. Only the star topology, because the hub holds the token
  4. Only the bus topology, because the token follows the bus
Show answer

Correct answer: It is not limited to any particular topology

It is often seen in rings, but the token order need not match the physical order.
