233 Questions with Verified Answers
It is a network of users that share computer resources in a limited area. -
CORRECT ANSWER LAN
Local Area Network - CORRECT ANSWER LAN
How are Local Area Networks defined? - CORRECT ANSWER In terms of protocol
and the topology used for accessing the network.
A set of rules established for users to exchange information - CORRECT ANSWER
Protocol
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
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 topology
, Topology that uses twisted-pair cables with modular plugs to connect computers
and other networking devices. - CORRECT ANSWER Star topology
Topology whereas each device is connected to a switch or hub - CORRECT
ANSWER Star
A switch or hub facilitates the transfer of data between networking devices in this
topology - CORRECT ANSWER star
Transmits data to all the devices connected in the star network - CORRECT
ANSWER hub
Also called a multiport repeater - CORRECT ANSWER hub
Not meant for large networks, but are still used in some smaller, slower speed
LANs - CORRECT ANSWER hub
A transmission from a hub in a star network to all the devices in the network
connected to the hub - CORRECT ANSWER broadcast
Stores the hardware or physical address for each device connected to its ports in
a star network - CORRECT ANSWER switch
Sends data transmissions directly to the port of the destination device on the
network - CORRECT ANSWER switch
The physical input/output interfaces to the networking hardware - CORRECT
ANSWER port
Where the cables physically connect to each other or a central switch or hub -
CORRECT ANSWER Port
Only the intended destination device on this network will see the data traffic -
CORRECT ANSWER star
