BICSI IN101 Exam Questions
and Answers Graded A+ 2026
update
Professionalism - ANSWER-the competence or skill expected of a professional
(How you look, sound, and feel)
Actions of a professional - ANSWER-Refrain from acts that cause background
checks, time management, avoid arguments, park appropriot, do not steal time
Principle of transmission - ANSWER-The movement of information in either analog
or digital form through copper conductors and fiber strands
AC - ANSWER-Alternating current
Analog signal - ANSWER-A signal in the form of a wave using continuous variations
of physical characteristics (constant voltage)
Bandwidth - ANSWER-A range of frequencies available for signaling expressed in
hertz (potential capacity of signals traveling at once)
,Bel - ANSWER-A ratio for analog signal strength (10 dBs)
Current (I) - ANSWER-The flow of electrons in a conductor (Amps)
Decibel (dB) - ANSWER-A ratio for analog signal strength (1/10 BEL)
DC - ANSWER-Direct current
Digital signal - ANSWER-Signal in the form of sequences of discrete pulses (binary
signal)
EMI - ANSWER-Electromagnetic interference
Frequency - ANSWER-The number of cycles that a signal completes in a given time
Hertz (Hz) - ANSWER-standard for measurement used for measuring frequency in
cycles per second. (60 Hz = 60 completed cycles per second)
Power (P) - ANSWER-The amount of energy transferred per unit time required to
operate a device
Volt (V) - ANSWER-A unit of measurement for electromotive force
,Copper cabling - ANSWER-Most common media for data transmission. Data is
transmitted as electrical pulses. (Cat 5, Cat 5e, Cat 6)
Attenuation - ANSWER-The loss or weakening of a signal between two point
expressed in dBs (a ratio of signal sent and signal received)
AWG - ANSWER-American wire gauge
Balanced twisted pair - ANSWER-A type of wiring where a pair of conductors
continually twist inside the cable to reduce or eliminate the possibility of EMI
from other conductors in the cable (blue and blue white will be twisted together)
Capacitance - ANSWER-the ability of a conductor to store electrical energy
coaxial cable - ANSWER-Cabling with a central metallic inner conductor and a
separated enclosed outer conductor by a dielectric material like a metallic braid
Crosstalk - ANSWER-Unwanted transfer of a signals electromagnetic energy (blue
interfering with orange)
Impedance (Z) - ANSWER-The total opposition that a circuit cable or compound
offers to the flow of altering current (measured in ohms)
Inductance - ANSWER-The property of an electrical force field built around a
conductor when current flows through it
, Insertion loss - ANSWER-The signal loss resulting from the insertion of a
component (attenuation when a new signal is transmitted)
NVP - ANSWER-Nominal velocity of propagation (coefficient used to determine
the speed of transmission relative to the speed of light)
Ohm (R) - ANSWER-The measure of electrical resistance
Ohms law - ANSWER-The mathematical relationship among electrical current
resistance and voltage
Ohms law formula - ANSWER-V
I|R
Resistance - ANSWER-A measurement of opposition a material offers to the flow
of direct current (measured in ohms)
Return loss - ANSWER-A ratio of the power of the outgoing signal to the power of
the reflected signal
USOC - ANSWER-Universal service order code
Optical fiber cabling - ANSWER-Transmits data modulated as light pulses
