Q. In what circumstances is a token-passing network more effectual than an Ethernet network?
Answer: A token ring is extremely effective under high sustained load as no collisions can occur and every slot may be used to carry a message, providing high throughput. A token ring is less efficient when the load is light (token processing takes longer than bus access therefore any one packet can take longer to reach its destination) or sporadic.
