CABLING

Three types of Cable

1.      Coaxial  ----- Specially using for T.V Connection

1.      Fiber Optic

 

1.      Twisted Pair

 

 

There are two types of Twisted Pair

(STP)                                                                                         (UTP)

Shielded twisted pair cable                                          Unshielded twisted pair cable
