STUDY GUIDE COMPLETE QUESTIONS AND
ANSWERS
◉ The coaxial cable that is looped through each networking device
to transmit data in a bus topology Answer: ThinNet
◉ In this topology, all devices on the network can see each other's
data traffic. 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. Answer: Bus
topology
◉ What are the disadvantages of a bus topology? 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? Answer:
Bus topology
◉ What is the most common topology used in today's LANs?
Answer: Star topology
◉ Topology that uses twisted-pair cables with modular plugs to
connect computers and other networking devices. Answer: Star
topology
◉ Topology whereas each device is connected to a switch or hub
Answer: Star
◉ A switch or hub facilitates the transfer of data between
networking devices in this topology Answer: star
◉ Transmits data to all the devices connected in the star network
Answer: hub
◉ Also called a multiport repeater Answer: hub
◉ Not meant for large networks, but are still used in some smaller,
slower speed LANs Answer: hub
, ◉ A transmission from a hub in a star network to all the devices in
the network connected to the hub Answer: broadcast
◉ Stores the hardware or physical address for each device
connected to its ports in a star network Answer: switch
◉ Sends data transmissions directly to the port of the destination
device on the network Answer: switch
◉ The physical input/output interfaces to the networking hardware
Answer: port
◉ Where the cables physically connect to each other or a central
switch or hub Answer: Port
◉ Only the intended destination device on this network will see the
data traffic Answer: star
◉ What is an advantage of the star topology? 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? Answer: A device can be
removed or added without disrupting other devices on the network
