Exam with Verified Questions and 100% Correct
Answers
American Wire Gauge (AWG) - (ANSWER)A system used to provide a standard
reference for comparing various physical demensions of conductor materials. The
greater the wire diameter the smaller the AWG value.
Attenuation - (ANSWER)The decrease in magnitude or the power loss of a signal
that propagates between two points, expressed in (dB) as the ratio of received
signal to transmitted signal level.
Bandwidth - (ANSWER)The information-carrying capacity of a system. Expressed
in the range of analog frequencies (e.g. 0Hz to 1 MHz) that can be transported or
processed by the system.
Capacitance - (ANSWER)A property of conductors that allows storage of electrical
charges when potential differences (voltages) exist between the conductors.
Measured in farads (F).
Crosstalk - (ANSWER)The unwanted transfer of a signal's electromagnetic energy
from one or more circuits to other circuits.
Impedance (Z) - (ANSWER)The total opposition to current flow is called
________. Measured in ohms.
, 2
Inductance - (ANSWER)The property of an electromagnetic field built around a
conductor that opposes any changes in current flow in a circuit, both AC and
varying DC. The basic unity of inductance is a Henry (H).
Insertion loss - (ANSWER)The measure of signal loss resulting from the insertion
of a component, or link, or channel, between a transmitter and receiver (often
referred to as attenuation).
Nominal Velocity of Propagation (NVP) - (ANSWER)A ratio of the speed of
transmission along a cable relative to the speed of light in a vacuum. It is often
stated in percentages.
Resistance - (ANSWER)The property of a conductor to resist the flow of electricity
through it. Expressed in ohms.
Return Loss - (ANSWER)A ratio of the power of the outgoing signal to the power
of the reflected signal. Expressed in decibels.
Analog, Digital - (ANSWER)The information transmitted by an ICT system can
originate in tow forms: ________ and ________.
Megahertz - (ANSWER)Which of the following quantifies the bandwidth of a
cabling system in a frequency range of interest?
, 3
Full Duplex - (ANSWER)Communication that happens in two directions at the
same time.
Bit - (ANSWER)The basic unit of digital information
Decibel (dB) - (ANSWER)The unit used to express system gain and loss.
Frequency - (ANSWER)The number of cycles a signal is repeated in a period.
Half Duplex - (ANSWER)Communication between two devices whereby
transmission takes place in only one direction at a time.
Simplex - (ANSWER)A one-way mode of communication. Radio
and television broadcasts are simplex mode transmissions.
Series-11 - (ANSWER)The type of cable used for video backbone distribution.
100 ohms at 75 Mhz - (ANSWER)Balanced twisted-pair cables have a nominal
characteristic impedance of __________
Delay Skew - (ANSWER)The difference in arrival time between the fastest and the
slowest signal in a UTP wire pair. Expressed in nanoseconds and is length
dependent.
