And OA Set Questions And Answers
It is a network of users that share computer resources in a limited area. ANS LAN
Local Area Network ANS LAN
How are Local Area Networks defined? ANS In terms of protocol and the topology used for
accessing the network.
A set of rules established for users to exchange information ANS Protocol
The network architecture used to interconnect the networking equipment. ANS Topology
What are the most common topologies for LANs? ANS Ring, Bus, and Star
Uses a token that is placed in the data channel and circulates around the ring. ANS Token Ring
topology
A deterministic network ANS Token Ring Topology
Each station connected to the network ensures access for transmission of its messages at regular or
fixed time intervals ANS Deterministic
What are the disadvantages of the Token Ring system? ANS 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?
ANS 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?
ANS 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.
ANS Token ring hub
How does the token ring hub improve the network? ANS It improves the reliability of the
network.
Topology whereas the computers share the media or coaxial cable for data transmission. ANS
Bus topology
The coaxial cable that is looped through each networking device to transmit data in a bus topology
ANS ThinNet
In this topology, all devices on the network can see each other's data traffic. ANS 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. ANS Bus topology
What are the disadvantages of a bus topology? ANS "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? ANS Bus topology
What is the most common topology used in today's LANs? ANS Star topology
, Topology that uses twisted-pair cables with modular plugs to connect computers and other
networking devices. ANS Star topology
Topology whereas each device is connected to a switch or hub ANS Star
A switch or hub facilitates the transfer of data between networking devices in this topology ANS
star
Transmits data to all the devices connected in the star network ANS hub
Also called a multiport repeater ANS hub
Not meant for large networks, but are still used in some smaller, slower speed LANs ANS hub
A transmission from a hub in a star network to all the devices in the network connected to the hub
ANS broadcast
Stores the hardware or physical address for each device connected to its ports in a star network
ANS switch
Sends data transmissions directly to the port of the destination device on the network ANS switch
The physical input/output interfaces to the networking hardware ANS port
Where the cables physically connect to each other or a central switch or hub ANS Port
Only the intended destination device on this network will see the data traffic ANS star
