Things to know which will help with qubes

I’m new to computing in general. I’m very interested in qubes and the way it works. I’m looking to learn more about computing in general but also more specifically on security e.g qubes.

Any recommended reading/YouTube vids. OK with books on more specific topics. But also need some high level info/books.
