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 of
protocol 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? - Answer✔✔-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? - 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? - 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? - 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. - Answer✔✔-Token ring hub
How does the token ring hub improve the network? - Answer✔✔-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? - Answer✔✔-
Bus topology
What is the most common topology used in today's LANs? -
Answer✔✔-Star topology
Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices. - Answer✔✔-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
