One day, my friends asked me about their local connectivity. They said something like they’re bought the Lan Cable and they tested it. It works good with no problems of course. But, the problem they wanted to solve is how to makes their own Lan Cables in the future.But first, how to choose between Straight one or Cross one to create. So here is the difference for us who still confuses about Straight Lan cable and Cross Lan Cable:

 

  1. The Straight one is always uses for the connectivity between the computer(PC/LAPTOP) with HUB/SWITCH, when the Cross one is always uses for the connectivity between the computer(PC/LAPTOP). My friends said that they cable was Straight one and used by them to plays Locally between computer. By my experience, it won’t connects except we don’t know what type of Cable we are using.
  2. To know the difference between the two types, it’s always good to remember the Straight cable color. We can see it from the underside of the Plug.The colors for Straight are(Orange-White, Orange, Green-White, Blue,  Blue-White, Green, Brown-White, Brown). Well, this is for the first plug. If it’s the Straight one, the another Plug must be have the same combination. If it’s the Cross one, the another Plug must have a different combination. For the cross one, the color change position, they are the FIRST color change place with THIRD color, and the SECOND color change place with the SIXTH color(1-3, 2-6). So, the color must be(Green-White, Green, Orange-White, Blue,  Blue-White, Orange, Brown-White, Brown). 

So, now we already know a bit about the difference between the Straight Cable and the Cross Cable in this short post. The next upcoming Topics, I will write about my experience for How-to-Create-the-Lan-Cable by ourself and some Internet Connectivity troubleshoots.
