Only stuff I can tell you is:
-UTP stands for Unshielded Twisted Pair.
-In each pair, the wires are twisted around each other, which is a method of reducing magnetic interference by means of exposing each wire to an equal amount of interference on a given side of the wire. So if the wires weren't twisted, one wire would be closer to any given source of interference, thus unequally corrupting the signal, where as in a twisted pair, both wires are equally close to the source of interference because they wrap around each other.
-Shielded Twisted Pair has a thin foil sheath which acts to contain internal interference and repel external interference, but UTP does not have this, making it subtantially cheaper than STP.
Can't think of anything else. Not sure if that's relevant to ya, but hope it helps.
Insiiiiiiiiiiiiiiiiiiiiiiiide!
