This method is utilized to stop magnetic field inter reaction (induction) between the signals that are carried on the other pairs.
Dunno. "Quad" usually refers to the shielding (such as TV antenna coaxial cable), "CAT" usually refers to four-pair twisted pair. "CATn" (CAT3~CAT6) is four-pair, twisted-pair, unshielded cabling most commonly used in Ethernet computer network cabling. Refine the question, we can help out.
4-20ma is a type of signal transmission.A process value, such as pressure, RPM, or whatever, is converted into a current in the range of 4ma to 20ma and sent out on a twisted pair cable.The receiver passes the current through a resistor, converting it back to voltage, and processes it accordingly. If that resistor were 250 ohms, the voltage would be 1-5v.An offset of 4ma is used so that the receiver can detect an open connection.The ground or power reference is usually maintained at the transmitter, but sometimes it is at the receiver.A twisted pair cable is used so that the effect of common mode noise is minimized.The receiver is usually an opamp so that the effect of common mode voltage is minimized.
No difference in terms of number of wires used.

"Cable" most often refers to a wiring method manufactured with more than one conductor. Examples would be the triplex (3 twisted wires) that powers most homes and the NM cable used for branch circuits in homes. But I have heard of single conductors referred to as cables, probably because of their size.
The twisting in a twisted pair cable helps make the cable immune to electromagnetic interference. These cables are of two types: Shielded and unshielded twisted pair.
if by "twisted pair cable" you mean a cat5 cable which is commonly used as an ethernet cable. then it´s made of copper.
with RJ 45 conecter & unshilded twisted pair cable
twisted pair cable can used as LAN connections....for example CAT5 and CAT6 both twisted pairs.
Twisted pair wiring is a digital signal.Coaxial cable is an analog signal.

Shielded Twisted pair cable
A twisted pair cable consists of two copper conductors, each one with its own plastic insulation and twisted together
Twisted pair cables were invented by Alexander Graham Bell in 1881.
CAT 5 Cable and RJ 45 Cable (Twisted-pair Ethernet). Unshielded twisted-pair (UTP) cable
Both the coaxial cable and twisted pair cable have a basic connection medium for network cabling. <<>> Coaxial cable can be used for transmission of RF (radio frequencies) whereas Cat 5 (twisted pairs cable) can not.
Mainly in LAN we can use 4 types of cables: 1) STP - Shielded Twisted Pair 2) UTP- Unshielded Twisted Pair UTP have 2 types 1 is Straight Cable 2 is Cross Cable 3) Coaxial Cable 4) Fiber Optic Cable
