So what is a computer network? Well, first, what is a network? The definition of a network is "A group or system of interconnected people or things"
So, it would be fair to say, a computer network would be “A group or system of interconnected computers” right?
And that’s exactly what it is. A computer network is anything where more than one computer is connected.
Traditionally, a computer network would consist of desktop computers, servers, printers, etc.
These days, we live in a connected world. We still have desktops, servers, and printers, but now we have a vast number of smart devices connected to our networks as well.
Most of you will have a mobile phone, maybe a tablet. Security cameras and even smart lighting systems can be found on networks! And the list goes on and on!
Networking has changed the world and how we live in it.
It’s a topic I still get excited about and there is no shortage of new things to learn.
We will go over a lot of this in more details as we go but that enough for now

    Thank you, everyone, for your comments! I know it's been a while. What you don't see is the work that goes on behind the scenes. New designs, creating all of the animation, audio equipment etc. I'm happy to say uploads should be a bit more frequent now. Thanks again for your support.

    Good overview of computer networking! I liked your comparisons of networking at the home and Internet levels, making it easier to understand the importance of networks everywhere. For those using the video to understand their own home networks though, I feel that including a comment about how routers and modems in their homes work to bring them Internet would make the video all the more special. Great job!

    Looks very promising. And pretty amazing to watch. I actually started going to IT classes. And everytime, I mean every f***ing time our teacher asks us a question like this, all of us becomes brainless to answer the question. He tried to make us present presentations but this time he told a little back story of his teaching life. So he gave the idea to watch videos bcuz that's how he learned many things all by himself. He mentioned that he couldn't learn a thing when he went to classes first. So better be worth it.
