Cables in IT.


A large number of people get confused quite easily, when it comes to computer cables, because there are so many of them. But let’s face it, computers are designed by smart people, and they always try to come up with foolproof methods.

If we believe that designers are smart, we could also believe that every cable type looks differently.

Let me take you back 20 or 30 years in time when people created the first computers that could have been assembled at home. They had to figure out a method that encourages people not to try to plug things in the wrong hole, therefore creating short circuit or worse.

Over the years, many computer standards have been born and every single one of them got a new type of plug which looked absolutely different than the ones before.

So you can be sure that if your plug fits, then you are doing the right thing. Just remember your childhood, when you – perhaps – played the famous game of fitting shapes into their proper holes: triangles into triangle holes, circles in the circle shaped holes and so on.

All was well until somebody came up with the idea of the USB cable. Now we have three types of USB: 1.0, 2.0, 3.0 and they use the same cable. What’s the difference, then? The speed: the USB 3.0 is the fastest and newest.

So you can plug in a USB 2.0 device into a USB 1.0 socket and the only thing you will experience is that the data stream is very slow.

Regarding other cables, it is not very complicated because it’s impossible to plug in a monitor cable into a network socket. Again, because of the shape difference.

My advice: if you wish to figure out what kind of cable you need to buy is to search for computer plug type images and compare them to the one your device has.
