I'd like to learn more about networking in a structured way.

Title. What do you recommend?

I'm a hobby programmer with some experience in C#, C++ and HLSL and I've been dabbing with programs such as Sonarr, Radarr and Torrents and the whole thing just fascinates me.

I'd love to learn everything there is to know about networks, starting from the ground up.

I'm looking for technical courses on how things work, just anything: Protocols, how LAN works, Torrents, Ports, etc.

Digital media would be preferred.

Thanks!
