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

signaling expressed in hertz (potential capacity of signals traveling at once)
Cable loss - CORRECT ANSWERS The attenuation of a signal as it
passes through optical fiber cable
