It is a network of users that share computer resources in a
limited area. (ANSWER LAN
Local Area Network (ANSWER LAN
How are Local Area Networks defined? (ANSWER In terms ofprotocol
and the topology used for accessing the network.
A set of rules established for users to exchange information
(ANSWER Protocol
The network architecture used to interconnect the networking
equipment. (ANSWER Topology
What are the most common topologies for LANs? (CORRECT) -
✅Ring, Bus, and Star
Uses a token that is placed in the data channel and circulates
around the ring. (ANSWER Token Ring topology
A deterministic network (ANSWER Token Ring Topology
Each station connected to the network ensures access for
transmission of its messages at regular or fixed time intervals
(ANSWER Deterministic
What are the disadvantages of the Token Ring system? (CORRECT) -
✅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? (ANSWER The token ring path
must be temporarily broken or interrupted if a computer orany
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? (ANSWER Connect each
computer or device on the network to a central token ringhub.
A device that manages the passing of the token instead of relying
on individual computers to pass it. (ANSWER Token ring hub
How does the token ring hub improve the network? (CORRECT) -
✅It improves the reliability of the network.
Topology whereas the computers share the media or coaxial cable
for data transmission. (ANSWER Bus topology
The coaxial cable that is looped through each networking device
to transmit data in a bus topology (ANSWER ThinNet
In this topology, all devices on the network can see each other's
data traffic. (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.
(ANSWER Bus topology
What are the disadvantages of a bus topology? (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) -
✅Bus topology
What is the most common topology used in today's LANs? (CORRECT)
- ✅Star topology
Topology that uses twisted-pair cables with modular plugs to
connect computers and other networking devices. (CORRECT) -
✅Star topology
Topology whereas each device is connected to a switch or hub
(ANSWER Star
A switch or hub facilitates the transfer of data between
networking devices in this topology (ANSWER star
Transmits data to all the devices connected in the star network
(ANSWER hub
Also called a multiport repeater (ANSWER hub
Not meant for large networks, but are still used in some smaller,
slower speed LANs (ANSWER hub
A transmission from a hub in a star network to all the devices in
the network connected to the hub (ANSWER broadcast
