To Understand cable composition in networking

Ok guys, let's start our study. it's an easy thing to share everything you have, now. I mean the data that you have. did you ever imagine you went to computer to get a lot of data for your jobs. you had to take any flash disk or anything like this. you copy it and you open in your pcs or notebook.
for 20 years ago it's an usual thing. Nobody said it very complicated. But today nobody want to do that. why?
Because all computers are connected to a network.
look at the picture below.

 

All the computers in an organization are connected to anothers computer.

What infrastuctures need to build an computer network?

Good question, Ok look at the picture again. all computers are connected to switch (at the central of picture). Lines connect every computer to central point (switch). line represents a media to connect every point at the picture.

one of media to transmites data is cable. for this lesson i will describe about UTP cable Cat.5

Can i start.

first you cut UTP cable min. 0,5 m. if you cut less than 0,5 m, i worry you will get some trouble to apply it to your computer or netbook.

next peel the cable, you can find 8 pair of cable in shield.

if you want to make straight cable you have to according the rules below:

in left side the composition are :

White Orange
White Orange

No	Left Side	No	Right side
1	White Orange	1	White Orange
2	Orange	2	Orange
3	White Green	3	White Green
4	Blue	4	Blue
5	White Blue	5	White Blue
