Cat 5 UTP (unshielded twisted pair) has 4 pairs of wires. They come in both solid core and softcore/messy core (what do you call it) versions.
CAT 6 UTP looks and feels the same and basically is the same. The only difference is the quality of the cables (sometimes not even that), the shielding characteristics of the connectors and of course....the price.
yesterday i have used this tip to double the gauge of a chopper wire
you have a very nice face ctc :D
not the multicoloured kind anyway
I ordered my first reel of coloured ribbon cable on Saturday night. Having seen in Oddbot's pics I just couldn't resist spend three times as much as for plain grey ribbon cable.
I learned the twisty trick from my grandfather about 40 years ago using a pump-action mechanical device that twisted metal sack ties. The second part of the trick, is not to twist the wires too tightly. If you do, there's a danger that you'll break the metal wire inside the insulation.
