Twisted pair wires have twists that are a certain number of twists per foot depending on twisted bundle size. The purpose of the twists is so the magnetic field that rises and collapses around each wire within the twisted pair cancel each other out since they are of opposite polarity.

The coaxial cable is just a single conductor within a grounded braid or foil jacket to help prevent unwanted magnetic fields (signals) from entering the actual signal wire that is in the center.

How do you interconnect incompatible LANs?

I am not sure what you mean by incompatible... But routers serve as connection points between different networks. Also if you meant fiber optic to twisted pair to coax then there are special converters that allow to do that.


What are the advantages of Ethernet over Coax?

Using coax, you just do one long cable run, rather than with twisted pair where you do an individual run for each computer/terminal. Problem? coax's max is 10 Mbit/s, and every computer has to take turns accessing the coax. Using 10 Mbit/s twisted-pair, each computer has its own, dedicated connection to the hub/switch/router, so you're not slowed down when more than one comptuer wants access.


What is the difference between shielding and screening effect?

when we use some metal wrap around a single pair it is called shield like STP ( shilelded twisted pair cable) , when all shielded pair are overall wrapped by some metal it is called screen for example S/STP that is screened shielded twisted pair cable ,


What is physical description for the twisted pair cables?

How many twisted pairs of wires are typically used in a leased line between two routers?

Ans:- Two pair of twisted pair Cable


Why is a twisted pair cable is not used for LAN connectivity?

Twisted pair is less sensitive to noise and crosstalk as the two wires in the pair are so close together that they generally both pick up the disturbance identically, then the receiving circuit cancels this common mode disturbance out. Twisted pair is also much less expensive than fully shielded cables like coax.


What is lan wiring?

That is a LAN with cables as opposed to wireless LAN without cables. Network cables now mostly used for a wired LAN are UTP (unshielded twisted pair) CAT5E, although STP (shielded twisted pair) and CAT6 or CAT7 specifications are also used. Before COAX cables were used.


Max speed of coax?

Coax cable is OK for R.F. up to several gigahertz, over medium to short runs. For data, we went to twisted-pair with 100 megabit Ethernet, and twisted-pair is now used in 10 gigabit Ethernet. So... using Nyquist, you can probably use coax cable up to gigabit speeds over medium-short distances, but I'm not aware of anyone doing it. Maybe try a google search.


What type of twisted pair is suitable with star topology?

Does Shielded Twisted Pair wire follow the same standards as Unshielded Twisted Pair wire?

No


Why twisted pair wire is called twisted pair?

Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP).Twisted pair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it.Twisted pair comes with each pair uniquely color coded when it is packaged in multiple pairs. Different uses such as analog, digital, and Ethernetrequire different pair multiples.Although twisted pair is often associated with home use, a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive thancoaxial cable.The wire you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pinouts, depending on the kinds of wire the installation expects will be plugged in (for example, digital, analog, or LAN) . (That's why you may sometimes find when you carry your notebook computer to another location that the wall jack connections won't match your plug.)


What is the max distance Ethernet for a coax media?

500m, for 10Base5 thicknet - probably no installations left. For 10base2 thinnet, it's around 185 m - maybe some that have not moved on to twisted-pair of some kind..
