How Do Ethernet Cables Work?

If you're like me, I'm looking at the back of my PC and even startled to guess what the purpose of all these cables is.

I rarely dare to go behind the computer and try to figure out how everyone is doing what they need to do.

There are blues and blacks, short and long, thin and wide. I have cables for speakers, cables for the screen, keyboard and mouse.

I understand these but what about all the others? How are they able to work smoothly when I turn on the computer and still look so chaotic behind it? The computer cables that confuse me the most are the ones that make Ethernet working.

How can one (fairly small) cable connect an entire home network for Internet use? Even more fascinating, is its ability to create an entire office network.

What is Ethernet?

Ethernet builds LANs (local area networks) into a network. An Ethernet site, designed in 1973 by Bob Metcalfe, requires a network of at least two computers and an Ethernet cable to connect both.

This is where Cat 5 and Cat5e computers come into the picture. Ethernet Not Working.

Category 5 cables

Category 5 cables (now replaced by Cat5e cable) consist of twenty-four pairs of twisted and unprotected copper wires.

Cat 5 cables are not only used as cables for computers, they are used for things like ATMs and also for video.

Cat 5 cables are easy to spot because they are usually blue, and if there is ever any confusion in what it is, Cat 5 cables will have a "Cat 5" term encoded in white on the cable itself.

The sole purpose of these cables is to transmit information at high speed from the computers on the network.

To do this, these computers need to be equipped with a network interface card (NIC). Besides, they must be a network coordinator who will direct all the information.

When it comes to computer cables, Cat 5 cables are highways for travel information and the ultimate destination is your computer.
