Resistance
Resistance is expressed in Ohms, and is the property of a conductor to resist the flow of
electricity through it. V=IR
Inductance
Is a property of an electromagnetic field built around a conductor that opposes any change in the
current flow in a circuit
Capacitance
is a property of conductors that allows storage of electric charges when potential differences
exist between the conductors.
Impedance (V)
Total opposition of current flow measured in Ohms
American Wire Gauge (AWG)
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)
one million hertz, especially as a measure of the frequency of transmissions

Bandwidth
The amount of data that can be transmitted over a network in a given amount of time.
Decibel (dB)
A unit used to compare the loudness of different sounds.
Crosstalk
when data bleeds from one pair to another in a cable
Alien Crosstalk (AXT)
