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
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
Stores the hardware or physical address for each device connected to its ports in a star network
- Answer✔switch
