LAN - correct answer- It is a network of users
that share computer resources in a limited
area.
LAN - correct answer- Local Area Network
In terms of protocol and the topology used for
accessing the network. - correct answer- How
are Local Area Networks defined?
Protocol - correct answer- A set of rules
established for users to exchange information
Topology - correct answer- The network
architecture used to interconnect the
networking equipment.

Ring, Bus, and Star - correct answer- What are
the most common topologies for LANs?
Token Ring topology - correct answer- Uses a
token that is placed in the data channel and
circulates around the ring.
Token Ring Topology - correct answer- A
deterministic network
Deterministic - correct answer- 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. -
correct answer- 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. - correct answer- 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. - correct answer-
What is a solution to the troubleshooting and
maintenance disadvantages of the Token Ring
system?
Token ring hub - correct answer- 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. -
correct answer- How does the token ring hub
improve the network?
Bus topology - correct answer- Topology
whereas the computers share the media or
coaxial cable for data transmission.
, 4 | Page
ThinNet - correct answer- The coaxial cable
that is looped through each networking device
to transmit data in a bus topology
Bus topology - correct answer- In this
topology, all devices on the network can see
each other's data traffic.
Bus topology - correct answer- 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." - correct answer- What
are the disadvantages of a bus topology?
Bus topology - correct answer- Which topology
is seldomly used in modern networks?
