BICSI Installer Exam Newest 2025 Questions
and Correct Answers Graded A+
American Wire Gge (AWG) - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER-A property of conductors that allows storage of
electrical charges when potential differences (voltages) exist between the conductors.
Measured in farads (F).
Crosstalk - CORRECT ANSWER-The unwanted transfer of a signal's electromagnetic
energy from one or more circuits to other circuits.
Impedance (Z) - CORRECT ANSWER-The total opposition to current flow is called
________. Measured in ohms.
Inductance - CORRECT 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 - CORRECT 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) - CORRECT 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 - CORRECT ANSWER-The property of a conductor to resist the flow of
electricity through it. Expressed in ohms.
Return Loss - CORRECT ANSWER-A ratio of the power of the outgoing signal to the
power of the reflected signal. Expressed in decibels.
Analog, Digital - CORRECT ANSWER-The information transmitted by an ICT system can
originate in tow forms: ________ and ________.
Megahertz - CORRECT ANSWER-Which of the following quantifies the bandwidth of a
cabling system in a frequency range of interest?
Full Duplex - CORRECT ANSWER-Communication that happens in two directions at the
same time.
