The network architecture used to interconnect the networking equipment. -
Correct-answer-Topology
What are the most common topologies for LANs? - Correct-answer-Ring, Bus, and
Star
Uses a token that is placed in the data channel and circulates around the ring. -
Correct-answer-Token Ring topology
A deterministic network - Correct-answer-Token Ring Topology
Each station connected to the network ensures access for transmission of its
messages at regular or fixed time intervals - Correct-answer-Deterministic
What are the disadvantages of the Token Ring system? - Correct-answer-1. If an
error changes the token pattern, it can cause the token to stop circulating.

What is a disadvantage of the Token Ring system from the troubleshooting and
maintenance? - Correct-answer-The token ring path must be temporarily broken
or interrupted if a computer or any device on the network is to be removed or
added to the network.
What is a solution to the troubleshooting and maintenance disadvantages of the
Token Ring system? - Correct-answer-Connect each computer or device on the
network to a central token ring hub.
A device that manages the passing of the token instead of relying on individual
computers to pass it. - Correct-answer-Token ring hub
How does the token ring hub improve the network? - Correct-answer-It improves
the reliability of the network.
Topology whereas the computers share the media or coaxial cable for data
transmission. - Correct-answer-Bus topology
The coaxial cable that is looped through each networking device to transmit data
in a bus topology - Correct-answer-ThinNet

, 4|Page
In this topology, all devices on the network can see each other's data traffic. -
Correct-answer-Bus topology
Topology whereas each computer must wait for pauses in transmission or until
the transmission from one device is complete before initiating a new transmission
onto the network. - Correct-answer-Bus topology
What are the disadvantages of a bus topology? - Correct-answer-"1. Data can be
corrupted if ore than one device on the network transmits at the same time and
will have to be resubmitted.
2. The use of the shared coaxial cable prevents data transmission from being very
bandwidth-efficient."
Which topology is seldomly used in modern networks? - Correct-answer-Bus
topology
What is the most common topology used in today's LANs? - Correct-answer-Star
