Correct-answer-Token Ring topology M M




A deterministic network - Correct-answer-Token Ring Topology
M M M M M M




Each station connected to the network ensures access for transmission of its
M M M M M M M M M M M




messages at regular or fixed time intervals - Correct-answer-Deterministic
M M M M M M M M M




What are the disadvantages of the Token Ring system? - Correct-answer-1. If an

What is a disadvantage of the Token Ring system from the troubleshooting and
M M M M M M M M M M M M




maintenance? - Correct-answer-The token ring path must be temporarily broken
M M M M M M M M M M




or interrupted if a computer or any device on the network is to be removed or
M M M M M M M M M M M M M M M M




added to the network.
M M M M




What is a solution to the troubleshooting and maintenance disadvantages of the
M M M M M M M M M M M




Token Ring system? - Correct-answer-Connect each computer or device on the
M M M M M M M M M M M




network to a central token ring hub.
M M M M M M M




A device that manages the passing of the token instead of relying on individual
M M M M M M M M M M M M M




computers to pass it. - Correct-answer-Token ring hub
M M M M M M M M




How does the token ring hub improve the network? - Correct-answer-It improves
