TYPES OF CABLE

CABLE - It is a medium that connects computer in a network

TYPES OF CABLE

1. TWISTED PAIR CABLE

                                     

                                  

                                 ➤   common type of cable.

                                 ➤   have eight individual copper wire bundled together and covered with an                                                insulting material.

                                ➤   the copper wire is always color-code with a plastic insulation's and they are                                            twisted in pairs of a total of four pairs.

TYPES OD TWISTED PAIR CABLES

a. STP ( SHIELDED TWISTED PAIRS)

    ↣ often in used "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 (UNSDEHIELD TWISTED PAIRS)    

 ↣is the most common form of twisted pair wiring                                                                                   ↣it is less expensice 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 the light beams to travel without outer                                             interference

THE DIFFERENCE BETWEEN STRAIGHT - THROUGH CABLE AND CROSS - OVER CABLE

STRAIGHT - THROUGH CABLE

*used to connect different type of devices 

(computer - switch), (switch - router), (router - computer).

                              

CROSS - OVER CABLE

*used to connect same type of devices

   (computer - computer), (switch - switch), (router- router)
