It is a network of users that share computer resources in
a limited area. - correct answers LAN
Local Area Network - correct answers LAN
How are Local Area Networks defined? - correct
answers In terms of protocol and the topology used for
accessing the network.
A set of rules established for users to exchange
information - correct answers Protocol
The network architecture used to interconnect the
networking equipment. - correct answers Topology
What are the most common topologies for LANs? -
correct answers Ring, Bus, and Star
,Uses a token that is placed in the data channel and
circulates around the ring. - correct answers Token
Ring topology
A deterministic network - correct answers Token Ring
Topology
Each station connected to the network ensures access
for transmission of its messages at regular or fixed time
intervals - correct answers Deterministic
What are the disadvantages of the Token Ring system?
- correct answers 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 answers
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 answers 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
answers Token ring hub
How does the token ring hub improve the network? -
correct answers It improves the reliability of the
network.
Topology whereas the computers share the media or
coaxial cable for data transmission. - correct answers
Bus topology
The coaxial cable that is looped through each
networking device to transmit data in a bus topology -
correct answers Thinnet
In this topology, all devices on the network can see each
other's data traffic. - correct answers 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 answers Bus topology
What are the disadvantages of a bus topology? - correct
answers "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 band efficient."
Which topology is seldomly used in modern networks? -
correct answers Bus topology
What is the most common topology used in today's
LANs? - correct answers Star topology
Topology that uses twisted-pair cables with modular
plugs to connect computers and other networking
devices. - correct answers Star topology
Topology whereas each device is connected to a switch
or hub - correct answers Star
A switch or hub facilitates the transfer of data between
networking devices in this topology - correct answers
star
Transmits data to all the devices connected in the star
network - correct answers hub
