,Question 1
It is a network of users that share computer resources in a limited area.
Correct Answer
LAN

Question 2
Local Area Network
Correct Answer
LAN


Question 3
How are Local Area Networks defined?
Correct Answer
In terms of protocol and the topology used for accessing the network.

Question 4
A set of rules established for users to exchange information
Correct Answer
Protocol

Question 5
The network architecture used to interconnect the networking equipment.
Correct Answer
Topology

Question 6

,Question 9
Each station connected to the network ensures access for transmission of its messages at regular or fixed time
intervals
Correct Answer
Deterministic

Question 10
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.

Question 11
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.

Question 12
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.

Question 13
A device that manages the passing of the token instead of relying on individual computers to pass it.
Correct Answer
Token ring hub

Question 14
How does the token ring hub improve the network?

Correct Answer
It improves the reliability of the network.

Question 15
Topology whereas the computers share the media or coaxial cable for data transmission.
Correct Answer
Bus topology




Trusted by thousands of students and professionals worldwide Page 3 of 33

, Question 16
The coaxial cable that is looped through each networking device to transmit data in a bus topology
Correct Answer
ThinNet

Question 17
In this topology, all devices on the network can see each other's data traffic.
Correct Answer
Bus topology


Question 18
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

Question 19
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."

Question 20
Which topology is seldomly used in modern networks?
Correct Answer
Bus topology

Question 21
What is the most common topology used in today's LANs?
Correct Answer
Star topology

Question 22
Topology that uses twisted-pair cables with modular plugs to connect computers and other networking devices.
Correct Answer
Star topology
