Detailed explanation-1: -The twisting design helps reduce internal electrical interference. Essentially, this provides shielding for each Ethernet wire. Interference from other pairs within a cable can cause crosstalk, reducing data transfer speeds and obstructing signal transmission.
Detailed explanation-2: -By twisting wires that carry an equal and opposite amount of current through them, the interference/noise produced by one wire is effectively canceled by the interference/noise produced by the other. A twisted pair also improves rejection of external electromagnetic interference from other equipment.
Detailed explanation-3: -If a pair of wires is twisted together, since they are of opposite polarity, the electromagnetic signals produced by the two wires cancel each other. This tends to decrease the sensitivity of the neighboring wires to interference.
Detailed explanation-4: -Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves rejection of external electromagnetic interference. It was invented by Alexander Graham Bell.
