currently learning network basics

I always wanted to learn the basics of how networks or the internet works as I was getting more and more into sysadmin stuff and ethical hacking. I tried a lot of times but it always seemed to be so difficult to get a foot in this topic.

I would usually start learning IP addresses only to find out that there are other things you need to learn first like MAC addresses or what a router is, or OSI model or TCP and UDP and so on. It was really difficult to know where to start.

So I thought about how I could really learn it from the ground up, and I remembered that Elon Musk talks about first principles thinking. Which means that you start from the basic truths about a topic. In this case it would be a question I asked myself: "Why do we even need networks?". I mean its obvious why we need networks, to connect everything together, to form the internet so everyone can use it.

But I still started with the question and im currently writing an article about it. I still came across a bunch of other topics that I would have to go over to even explain the basics of networks but I had to start somewhere. For example OSI model came in quick and the different layers for a connection, but I just quickly explained the basics of it and I will definitely write another article that just focuses on the OSI model.

So yeah, I finished that article and I already scheduled it to release it in a few weeks and started another article already about protocols and ports and that is also a really vast topic with a bunch of other things that connect to it. But I just tried to stay on the topic.

Anyway, im really hyped to finish those articles and write more as I really learn a lot by writing them and I also want to turn those articles into youtube video because I think explaining it in video form will give me an even better understanding of the topic and I might help other people to understand it.
