BICSI INSTALLER EXAM 2025
QUESTIONS AND ANSWERS
American Wire Gauge (AWG) - ANS 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 - ANS 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 - ANS 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 - ANS A property of conductors that allows storage of electrical charges when
potential differences (voltages) exist between the conductors. Measured in farads (F).
Crosstalk - ANS The unwanted transfer of a signal's electromagnetic energy from one or
more circuits to other circuits.
Impedance (Z) - ANS The total opposition to current flow is called ________. Measured in
ohms.
Inductance - ANS 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 - ANS 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) - ANS 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 - ANS The property of a conductor to resist the flow of electricity through it.
Expressed in ohms.
Return Loss - ANS A ratio of the power of the outgoing signal to the power of the reflected
signal. Expressed in decibels.
Analog, Digital - ANS The information transmitted by an ICT system can originate in tow
forms: ________ and ________.
Megahertz - ANS Which of the following quantifies the bandwidth of a cabling system in a
frequency range of interest?
Full Duplex - ANS Communication that happens in two directions at the same time.
Bit - ANS The basic unit of digital information
Decibel (dB) - ANS The unit used to express system gain and loss.
Frequency - ANS The number of cycles a signal is repeated in a period.
Half Duplex - ANS Communication between two devices whereby transmission takes place in
only one direction at a time.
