Cables, Which one??? 1

[baller1]

I am currently studying the structures of TCP/IP and NT Servers.My current assignment includes various questions about transmission mediums for various applications.

I am still not entirely clear about the pros and cons of two types of cables;

1) Coaxable Cable

2) Shielded Twisted Pair

The coaxial cable is hardly used anymore. A kind of cable with a solid central conductor surrounded by insulator, in turn surrounded by a cylindrical shield woven from fine wires. The shield is usually connected to electrical ground to reduce electrical interference. (descr. taken from FOLDOC-computing disctionary)

There's no Shielded twisted pair cable. however there is the Unshielded twisred pair cable (or UTP). it's made from 4-pairs of wires (8 wires in total). the wires of each pair are twisted together. this is the reason why this cables do not have to be shielded.

these days utp cables are the best choise since they have better characterisics than the coaxial cables.

I hoped i helped

michalis,
Shielded twisted pair cable is available in a Cat-5 rating. It is used in industrial and other electrically noisy areas for network communications.
Here is a link to one spec sheet:

Thank you for the info!!
I thought the shielding from twisting the pairs was enough!! Obviously i was wrong!
thank you again..
