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
port - ANS-The physical input/output interfaces to the networking hardware
Port - ANS-Where the cables physically connect to each other or a central switch or hub
