LAN - ANS It is a network of users that share computer resources in a limited area.
LAN - ANS Local Area Network
In terms of protocol and the topology used for accessing the network. - ANS How are Local
Area Networks defined?
Protocol - ANS A set of rules established for users to exchange information
Topology - ANS The network architecture used to interconnect the networking equipment.
Ring, Bus, and Star - ANS What are the most common topologies for LANs?
Token Ring topology - ANS Uses a token that is placed in the data channel and circulates
around the ring.
Token Ring Topology - ANS A deterministic network
Deterministic - ANS Each station connected to the network ensures access for transmission
of its messages at regular or fixed time intervals

1. If an error changes the token pattern, it can cause the token to stop circulating. -
ANS What are the disadvantages of the Token Ring system?
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. - ANS What is a disadvantage of the
Token Ring system from the troubleshooting and maintenance?
Connect each computer or device on the network to a central token ring hub. - ANS What is
a solution to the troubleshooting and maintenance disadvantages of the Token Ring system?
Token ring hub - ANS A device that manages the passing of the token instead of relying on
individual computers to pass it.
It improves the reliability of the network. - ANS How does the token ring hub improve the
network?
Bus topology - ANS Topology whereas the computers share the media or coaxial cable for
data transmission.
ThinNet - ANS The coaxial cable that is looped through each networking device to transmit
data in a bus topology
Bus topology - ANS In this topology, all devices on the network can see each other's data
traffic.
Bus topology - ANS 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.
"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." - ANS What are the disadvantages of a bus topology?
Bus topology - ANS Which topology is seldomly used in modern networks?
Star topology - ANS What is the most common topology used in today's LANs?
Star topology - ANS Topology that uses twisted-pair cables with modular plugs to connect
computers and other networking devices.
Star - ANS Topology whereas each device is connected to a switch or hub
star - ANS A switch or hub facilitates the transfer of data between networking devices in this
topology
hub - ANS Transmits data to all the devices connected in the star network
hub - ANS Also called a multiport repeater
hub - ANS Not meant for large networks, but are still used in some smaller, slower speed
LANs
broadcast - ANS A transmission from a hub in a star network to all the devices in the network
connected to the hub
switch - ANS Stores the hardware or physical address for each device connected to its ports
in a star network
switch - ANS Sends data transmissions directly to the port of the destination device on the
network
