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