BICSI INSTALLER QUESTIONS WITH
CORRECT ANSWERS 2026-2027
American Wire Gauge (AWG) - CORRECT ANSWER -
A system used to provide a standard reference for comparing various physical demensions of c
onductor 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 (v
oltages) 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, bet
ween 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 i
s 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 d
ecibels.
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 int
erest?
Full Duplex - CORRECT ANSWER -
Communication that happens in two directions at the same time.
Bit - CORRECT ANSWER -The basic unit of digital information
Decibel (dB) - CORRECT ANSWER -The unit used to express system gain and loss.
, Frequency - CORRECT ANSWER -The number of cycles a signal is repeated in a period.
Half Duplex - CORRECT ANSWER -
Communication between two devices whereby transmission takes place in only one direction a
t a time.
Simplex - CORRECT ANSWER -A one-way mode of communication. Radio
and television broadcasts are simplex mode transmissions.
Series-11 - CORRECT ANSWER -The type of cable used for video backbone distribution.
100 ohms at 75 Mhz - CORRECT ANSWER -Balanced twisted-
pair cables have a nominal characteristic impedance of
Delay Skew - CORRECT ANSWER -
The difference in arrival time between the fastest and the slowest signal in a UTP wire pair. Exp
ressed in nanoseconds and is length dependent.
10 Mhz - CORRECT ANSWER -For 100 Ohm 4-
[air cables, the maximum allowable propagation delay is measured at MHz for all catego
ries of cabling.
CMUC - CORRECT ANSWER -
The cable marking used for cables that are permeated for installation between carpet and subfl
oor.
Authority Having Jurisdiction (AHJ) - CORRECT ANSWER -
The building official, electrical inspector, fire marshal, or other individuals or entities responsibl
e for interpretation and enforcement of local building and electrical codes.
