Learning the fundamentals first (such as networking) is a good way forward. You will propably need to learn many other subjects along the way, such as how system services are handled, permissions in linux, linux system administration in general and so on.

If you just want the fundamentals of networking, these resources are pretty good:

And my favorite:

Feel free posting to this community with questions or try finding someone who can be your ballplank. Getting started can be very challenging before you've grasped the basics.

DigitalOcean's guides in general are pretty good for all sorts of things, whether it's a generic discussion of a concept like the ones you've posted, or a step-by-step guide for installing and configuring specific systems or software. Even if you're not using DO as a host, much of what they suggest is still very useful.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
DNS Domain Name Service/System
HTTP Hypertext Transfer Protocol, the Web
HTTPS HTTP over SSL
IP Internet Protocol
SSH Secure Shell for remote terminal access
SSL Secure Sockets Layer, for transparent encryption
TCP Transmission Control Protocol, most often over IP
VPN Virtual Private Network

FWIW Coursera will generally let you take courses for free if you apply for their financial aid. It's annoying the first time because you have to write a couple short essays but I've just written them once and use the same ones over and over without issue

Not free, but there are courses in udemy starting from 15€ for new customers. But be warned, these "basic" courses are between 15 and 25 hours of video. Network is not a topic you can teach yourself in one day.

I learned everything by experimenting with it. Back in the days, that was running my own local Apache for development on Ubuntu 7.10. And then I slowly started toying with different services, eventually got my own VPS, learned to firewall and lock things down. Eventually I got into VMs which got me to learn networking and how bridges work. Later on, I played with VPNs and as my needs grew the network and routing grew as well.

You can learn from tutorials but the real learning is the hands on experience.

VMs are free and cheap to run these days, make a VM, play with it, mess it up however you want, try to fix it, reinstall it as necessary. Try to find ways a bad actor could get to it and how to prevent it.
