TYPES OF CABLE

Cable - a medium that connects computer in a network

WHAT ARE THE TYPES OF CABLE?

1. Twisted Pair Cable

Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. Twisted pair comes with each pair uniquely color coded when it is packaged in multiple pairs. 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.

Two different types of twisted pair cable, unshielded twisted pair (UTP) and shielded twisted pair (STP) are used in different kinds of installations. 

a.) STP (Shielded Twisted Cable) - often used in noisy environments where a shield of metallic foil is wrapped around each of the wire pairs, with an additional overall shielding to protect against excessive electromagnetic interference.

 b.) UTP (Unshielded Twisted Pair) - the most common form of twisted pair wiring, less expensive and easy to work with than STP

2. Coaxial Cable

The standard media used by cable TV operators and it consists of a plastic insulator that separates the solid copper inner conductor and the woven, copper braid outer conductor

3. Fiber - Optic Cable

Has a reflective that allows light beams to travel without outer interference connecting a UTP cable involves the use of RJ45 connector. This is commonly used to connect devices on to a Local Area Network (LAN).
