Which of the following is most typical of a broadband network? - ANSWER-
Multiple analog channels
What components are common to all computer systems? - ANSWER-Processor
Memory
Storage
I/O
What does I/O stand for? - ANSWER-Input / Output
A NIC is a device used for: - ANSWER-Signaling
A sound card is what general type of computer component? - ANSWER-Input /
Output
Which of the following is managed by the OS? - ANSWER-Keyboard input
Screen display
,File I/O
Peripheral control
The primary purpose of a device driver is to control hardware under the
supervision of the OS. True or False? - ANSWER-True
Which of the following network topologies forms a closed loop? - ANSWER-Ring
Topology
Which of the following network topologies connects devices to a shared straight-
line cable? - ANSWER-Bus topology
When is UTP cable preferred over STP? - ANSWER-When there is little electrical
interference
Which connector type is used with Thinnet coaxial cable? - ANSWER-BNC
Which of the following cable types uses a T-connector to connect each NIC to the
cable? - ANSWER-Thinnet
Which of the following cable types can transmit data farthest? - ANSWER-Fiber
optic
How are bits represented on fiber optic cable? - ANSWER-Pulses (on/off) of light
, Which of the following are the two primary types of light sources in fiber optic
cables? - ANSWER-Laser diode and LED
What is the main advantage of star topology? - ANSWER-Ease of management
Which of the following would not be used in a typical star topology? - ANSWER-
Thinnet
How many wire pairs can be terminated on a 66 block? - ANSWER-25 or 50
What makes a crossover cable different from a patch cord? - ANSWER-A
crossover cable uses the 568A pattern on one jack, and the 568B pattern on the
other. A patch cord uses the same pinout pattern on both jacks.
What is the key reason that smart LAN administrators demand well-made cable
connections? - ANSWER-Bad cable connections degrade a network's performance.
What is the main advantage of using balanced signaling on a serial cable? -
ANSWER-The cable can be longer because balanced signaling is less vulnerable to
interference.
What term describes the number of wave crests that pass a fixed point during a
particular period of time? - ANSWER-Frequency
In data networking, this term is defined as "Signals may flow in either direction,
but not simultaneously". - ANSWER-Half-duplex
