WGU C172 Network and Security -
Foundations; PA and OA set Rated A+
It is a network of users that share computer resources in a limited area. ANSWERS-
LAN
Local Area Network ANSWERS-LAN
How are Local Area Networks defined? ANSWERS-In terms of protocol and the
topology used for accessing the network.
A set of rules established for users to exchange information ANSWERS-Protocol
The network architecture used to interconnect the networking equipment. ANSWERS-
Topology
What are the most common topologies for LANs? ANSWERS-Ring, Bus, and Star
Uses a token that is placed in the data channel and circulates around the ring.
ANSWERS-Token Ring topology
A deterministic network ANSWERS-Token Ring Topology
Each station connected to the network ensures access for transmission of its messages
at regular or fixed time intervals ANSWERS-Deterministic
What are the disadvantages of the Token Ring system? ANSWERS-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? ANSWERS-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? ANSWERS-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. ANSWERS-Token ring hub
How does the token ring hub improve the network? ANSWERS-It improves the reliability
of the network.
, Topology whereas the computers share the media or coaxial cable for data
transmission. ANSWERS-Bus topology
The coaxial cable that is looped through each networking device to transmit data in a
bus topology ANSWERS-ThinNet
In this topology, all devices on the network can see each other's data traffic.
ANSWERS-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. ANSWERS-Bus topology
What are the disadvantages of a bus topology? ANSWERS-"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? ANSWERS-Bus topology
What is the most common topology used in today's LANs? ANSWERS-Star topology
Topology that uses twisted-pair cables with modular plugs to connect computers and
other networking devices. ANSWERS-Star topology
Topology whereas each device is connected to a switch or hub ANSWERS-Star
A switch or hub facilitates the transfer of data between networking devices in this
topology ANSWERS-star
Transmits data to all the devices connected in the star network ANSWERS-hub
Also called a multiport repeater ANSWERS-hub
Not meant for large networks, but are still used in some smaller, slower speed LANs
ANSWERS-hub
A transmission from a hub in a star network to all the devices in the network connected
to the hub ANSWERS-broadcast
Stores the hardware or physical address for each device connected to its ports in a star
network ANSWERS-switch
Sends data transmissions directly to the port of the destination device on the network
ANSWERS-switch
