How many pairs of wires in unshielded twisted pair?
There are 4 pairs, 8 wires in total.
What do you mean by UTP-3?
Unshielded Twisted Pair Category 3. Can be used for 10Mb Ethernet or 2 phone lines, as it has 2 pairs of twisted wired inside.
With the use of unshielded twisted pair copper wire in a network what causes crosstalk with the cable pairs?
the magnetic field around the adjacent pairs of wire
What is a cat 5 cable and why is it used?
Cat-5 cable, sometimes called Ethernet cable, is short for Category 5 cable, a current industry standard for network and telephone wiring. Cat-5 cable is unshielded wire containing four pairs of 24-gauge twisted copper pairs, terminating in an RJ-45 jack. If a wire is certified as Cat-5 and not just a twisted pair wire, it will have "Cat-5" printed on the shielding.
Which network medium is composed of four pair of wires where the pairs are twisted together and bundle within a covering?
Twisted pairs
What is the difference between UTP and STP twisted pair cables?
* UTP for Unshielded Twisted Pair * STP for Shielded Twisted Pair * FTP for Foiled Twisted Pair * S/UTP for Screened Unshielded Twisted Pair * S/STP for Screened Shielded Twisted Pair * S/FTP for Shielded Foiled Twisted Pair* UTP cable has no shielding, only an insulation around the cables * STP cable has a metal shield around each twisted pair, all pairs together are in the cable covered by insulation * FTP cable has a metal shield around all pairs - "the cable"- together * S/UTP cable has a metal shield around all pairs - "the cable"- together(or would be the same as FTP) * S/STP cable has a metal shield around each twisted pair, and a metal shieldaround all pairs - "the cable"- together(or would be the same as S/FTP) * S/FTP cable has a metal shield around each twisted pair, and a metal shield around all pairs - "the cable"- together(or would be the same as S/STP) * UTP is unshielded, that's simple. * FTP and STP are ofted intermixed, sometimes S/UTP is also thrown in. In general it means the cable is shielded in one place. * S/FTP ans S/STP are of course often intermixed, both should get you a double shielded cable. * Unshielded twisted pair cable will do just fine if there are not too much electromagnic interferences (EMI), that's what the twisting is for. * Shielded cable will protect your signal better from interference. Though there are no guarantees of course, if the interference source is too strong it'll still influence things.Things like big electro motors (an elevator engine), powerfull speaker systems (festival rig), strong light installations (that same festival rig) or a nearby high-power cable are some examples of interference sources. * Evidently unshielded cable is typically more flexible then shielded cable. * I have no idea what the practical difference between FTP and STP cable would be, but it might have something to do with the flexibility rather then with the shielding effectiveness.

Why are cat5 cables twisted?
The same reason telephone transmission wire pairs are twisted: to improve transmission by reducing noise pickup. See related question on twisted pairs.
What best describes UTP?
it consists of a number of twisted pairs of two conductors (copper) each with simple colored plastic insulation. UTP is the most common type telecommunication medium in use today. it is mostly used in telephone system. UTP cable is available in seven different categories from category one to category five. each category cable has its own conductor's size electrical characteristic and twist er foot.category 1 & 2=> Basically use for voice communication and t- lines, datd rates up to 100Kbps &2Mbpps.category 3 => Basically used for computer networks, data rates up to 16MHz &10Mbps.category 4 => data rates up to 200MHz &200Mbps.category 5 => Support fast Ethernet, data rates up to 100Mbps.category 6 & 7 =Used in a big organizations for complex network data rates up to 200Mbps and Cat 7 data rates up to 600MHz.
What cabling consists of one or more insulated wire pairs encased in a plastic sheath?
That question is very vague. It could refer to varieties of power, telephone and computer network cabling. If you are referring to computer networking this is usually called UTP (unshielded twisted pair) cabling.

What is the difference between the various types of twisted pair cables?
From a networking perspective the two main types of twisted pair cable that have been used extensively; particularly with Ethernet, are Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP). The biggest difference between the two is the presence or absence of a shielding layer but all types use various twist periods to reduce the effect of electromagnetic interference (EMI) or noise and cross-talk interference.
Can twisted pair cable used for LAN connections?
twisted pair cable can used as LAN connections....for example CAT5 and CAT6 both twisted pairs.
