twork 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
What are the disadvantages of a bus topology? - CORRECT ANSWER-"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? - CORRECT ANSWER-Bus topology
What is the most common topology used in today's LANs? - CORRECT ANSWER-Star topology
Topology that uses twisted-pair cables with modular plugs to connect computers and other
networking devices. - CORRECT ANSWER-Star topology
,Topology whereas each device is connected to a switch or hub - CORRECT ANSWER-Star
A switch or hub facilitates the transfer of data between networking devices in this topology -
CORRECT ANSWER-star
Transmits data to all the devices connected in the star network - CORRECT ANSWER-hub
Also called a multiport repeater - CORRECT ANSWER-hub
Not meant for large networks, but are still used in some smaller, slower speed LANs - CORRECT
ANSWER-hub
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
What is an advantage of the star topology from the troubleshooting and maintenance? -
CORRECT ANSWER-A device can be removed or added without disrupting other devices on the
network
All devices are connected to each other - CORRECT ANSWER-mesh topology
What is an advantage of the mesh network? - CORRECT ANSWER-It provides full redundancy in
the network data paths
What is a disadvantage of the mesh network? - CORRECT ANSWER-The additional data paths
increase the cabling cost and the network hardware cost. It is also very complex.
What type of applications is the mesh topology suited for? - CORRECT ANSWER-high-reliability
applications
What type of applications is the mesh topology not suited for? - CORRECT ANSWER-general
networking applications
Open systems interconnect reference model - CORRECT ANSWER-OSI
Who was the OSI model developed by? - CORRECT ANSWER-The International Organization for
Standardization
What year was the OSI model developed? - CORRECT ANSWER-1984
