Answers|| Graded A+|| LATEST UPDATE

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