Ethernet communications is actually an FM radio frequency carrier of around 800-900 Megahertz (It's broadband but I believe the centre is around 837 MHz. The radio waves are feed into the twisted pair in phase/anti-phase balanced feeder arrangement. This cancels out any radiation that is emitted from the feeder (twisted pair) and also cancels out any external interference. The actual data is sent as a frequency division multiplex signal from each card using CMSA/CD (Carrier Sense Multiple Access/Carrier Detect). Each burst is served using a first come first served system.
If it wasn't twisted the signal would radiate from the feeder allowing clever people to receive the signals and decode the packets at distance using radio receiver equipment. It would also unbalance the feeder leading to standing wave problems which would reduce the distance that the cable would carry a signal and possibly lead to the RF amplifier circuit to fail in the network card. Standing waves are one of the reasons you should not bend a network cable with a radius of less than 2 inches. Doing so causes the cable to interfere with itself.

What utp stands for?
UTP stands for Unshielded Twisted Pair. This is a type of cable which has the shielding above the twisted cables for EMI/EMC protection.
What characteristic of UTP cable helps reduce the effects of interference?
the twisting of the wires in the cable
What is the shielding made of on a typical UTP cable?
Actually, a UTP cable doesn`t have any shielding. UTP stands for Unshielded Twisted Pair.
Why is balance an issue in UTP cables?

Where are UTP cables available for purchase?
UTP cables are available to purchase from a wide variety of retailers and stores. Wal-Mart and Target both carry UTP cables. Additionally, Best Buy, Frys, and Radio Shack also carry these cables. An individual may also find UTP cables at places like Amazon and eBay.
Characteristic impedance of cat 5e utp cables?
Characteristic impedance of cat 5e utp cables is 100 ohms.
What is a UTP coupler?
A UTP coupler is a small block to which you can connect two UTP cables to form a longer one. Handy if you have 2 short cables but need a long one.
What does utp cable relies on to reduce signal noise cause by emi and rfi?
Shielding
How is the magnetic field cancellation effect enhanced in UTP cables?
In UTP cables, the magnetic field cancellation effect is enhanced by twisting the pair of wires together. The twisting pattern helps to reduce crosstalk and electromagnetic interference between the wires, resulting in better signal integrity and performance. Additionally, using a balanced transmission method further enhances the cancellation effect by ensuring that any external magnetic fields affecting one wire will also affect the other wire identically, leading to cancellation.
Which type of network cable is more reliable STP or UTP?
STP is more reliable due to shielding.
Coaxial cables are less prone to interference than UTP Why?
Coaxial cables are shielded; thus preventing them from other interference. UTP cable means Unshielded Twisted Pair - thus it has no protection against incoming interference.
Dose STP or UTD provide more resistance to outside interference?
That would be STP versus UTP. STP provides more protection from interference, due to the shielding. "S" stands for "shielded" in this case. "U" means "Unshielded".That would be STP versus UTP.
