Detailed Answers Already Graded A+
A transmission from a hub in a star network to all the devices in the network
connected to the hub - CORRECT ANSWER-broadcast
Stores the hardware or physical address for each device connected to its ports in
a star network - CORRECT ANSWER-switch
Sends data transmissions directly to the port of the destination device on the
network - CORRECT ANSWER-switch
The physical input/output interfaces to the networking hardware - CORRECT
ANSWER-port
Where the cables physically connect to each other or a central switch or hub -
CORRECT ANSWER-Port
Only the intended destination device on this network will see the data traffic -
CORRECT ANSWER-star
,What is an advantage of the star topology? - CORRECT ANSWER-It improves
the efficiency of the available bandwidth of the network
It is a network of users that share computer resources in a limited area. -
CORRECT ANSWER-LAN
Local Area Network - CORRECT ANSWER-LAN
How are Local Area Networks defined? - CORRECT ANSWER-In terms of
protocol and the topology used for accessing the network.
A set of rules established for users to exchange information - CORRECT
ANSWER-Protocol
The network architecture used to interconnect the networking equipment. -
CORRECT ANSWER-Topology
What are the most common topologies for LANs? - CORRECT ANSWER-Ring,
Bus, and Star
,Uses a token that is placed in the data channel and circulates around the ring. -
CORRECT ANSWER-Token Ring topology
A deterministic network - CORRECT ANSWER-Token Ring Topology
Each station connected to the network ensures access for transmission of its
messages at regular or fixed time intervals - CORRECT ANSWER-Deterministic
What are the disadvantages of the Token Ring system? - CORRECT ANSWER-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? - CORRECT ANSWER-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? - CORRECT ANSWER-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. - CORRECT ANSWER-Token ring hub
How does the token ring hub improve the network? - CORRECT ANSWER-It
improves the reliability of the network.
Topology whereas the computers share the media or coaxial cable for data
transmission. - CORRECT ANSWER-Bus topology
The coaxial cable that is looped through each networking device to transmit data
in a bus topology - CORRECT ANSWER-ThinNet
In this topology, all devices on the network can see each other's data traffic. -
CORRECT ANSWER-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. - CORRECT ANSWER-Bus topology
