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.


    Great content. Thanks so much . I wish you could in the future touch some of the new topics added in CCNA syllabus 2020.Also I wish you could have a video on SCTP. Thanks once again

    I did a small 1 year networking course a while back. I liked it and did really well but need to refresh my memory so this is really great. I am currently 24 and am going to be undertaking a bachelor of science degree in computer networks and system management. It's never too late, i guess!
