,NVP - Answer: Nominal Velocity of Propagation
Insertion loss - Answer: The difference in the amount of power received before
and after something is inserted into the circuit.
Resistance - Answer: Resistance is expressed in Ohms, and is the property of a
conductor to resist the flow of electricity through it. V=IR
Inductance - Answer: Is a property of an electromagnetic field built around a
conductor that opposes any change in the current flow in a circuit
Capacitance - Answer: is a property of conductors that allows storage of electric
charges when potential differences exist between the conductors.
Impedance (V) - Answer: Total opposition of current flow measured in Ohms
American Wire Gauge (AWG) - Answer: A standard rating that indicates the
diameter of a wire, such as the conducting core of a coaxial cable or the twisted
pairs in a UTP cable.
Megahertz (MHz) - Answer: one million hertz, especially as a measure of the
frequency of transmissions

, Megabit (Mb) - Answer: Approximately one million bits. Often used as a
measurement of data transfer throughput.
Bandwidth - Answer: The amount of data that can be transmitted over a network
in a given amount of time.
Decibel (dB) - Answer: A unit used to compare the loudness of different sounds.
Crosstalk - Answer: when data bleeds from one pair to another in a cable
Alien Crosstalk (AXT) - Answer: Unwanted signal coupling from one permanent
link to another
USOC - Answer: Universal Service Order Code
Coaxial cable types - Answer: Series-6 and Series-11
Coaxial connectors - Answer: Series-6 uses BNC and F connectors
Series-11 uses F and N connectors
Fiber connectors - Answer: SC, ST, and SST(LC or
cladding - Answer: The glass or plastic shield around the core of a fiber-optic
cable. Cladding reflects light back to the core in patterns that vary depending on
