Cabling

My dad always tells me, " You must have cable if you'd like to succeed your career."


Cable Cable, what does that mean? XD


In terms of telecommunication and networking, cabling is a medium through which information usually moves from one network device to another.




Several types of cable are commonly used with LANS. But in some cases, a network utilizes only 1 type of cable.


There are 5 types of Cable:




1.Unshielded Twisted Pair ( UTP) 

- Wires are twisted.
- 4 pairs of wires
- each pair is twisted with a different number of twists per inch 
- eliminate interference from adjacent pairs and other electrical devices

Standard connector: an RJ-45 connector 




2.Shielded Twisted Pair ( STP )

- 2 individual wires wrapped in a foil shielding
- provide more reliable data communication
- suitable for environment with electrical interference
- the extra shielding might make the cable bulky
- Often used on networks like  Token Ring Topology




3. Coaxial Cabling

- has a single copper conductor at its center
- a plastic layer provides insulation between the center conductor and a braided
  metal field.
- The metal shields help to block outside interference


-Connector : BNC connector ( available for different types of adapters)




4. Fibre optics cable

-consists of a center glass core surrounded by several layers of protective materials

- transmits light rather than electronic signals eliminating the problem of electrical interference.

-ideal for certain environments that contain a large amount of electrical interference..

- able to transmit signals over much longer distances than coaxial and twisted pair.

My little reflection of the day: 

Today my classmates shared us the baby steps of creating a blog.Very interesting. And I realise that the particulars of a blog are much more complex than what I know superficially.

I think class presentation is very immportant as it clearly points out our ignorance. :)
