WHAT ARE THE DIFFERENT TYPES OF CABLE?

WHAT IS A CABLE?

Cable - it is a medium that connects computer in a network

TYPES OF CABLE

1.    Twisted-pair cable

- Is the most common type of cable.

- Have eight individual copper wires bundled together and covered with an insulating material.

- The copper wire is always color-coded with plastic insulations and they are twisted in pairs for a total of four pairs.

a.     STP – Shielded Twisted Pair

- 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

-   Is the most common form of twisted pair wiring.

-   It is less expensive and easier to work with than STP.

2.    Coaxial Cable

- the standard media used by cable TV operators.

- 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 coating that allows light beams to travel without outer interference.
