Can someone point me to a helpful beginners resource explaining some Linux basics? Like what is the difference between “distro”, which is what, like Ubuntu, fedora, Debian (? Or is that a category of distro?) And desktop environment which is what, KDE, Lubuntu, gnome? Like I don’t even know I have these categories right let alone understand why I’d pick one over another and what practical effects it will have- which apps will I/won’t I be able to install, etc…

I’m not expecting anyone to answer these questions for me, but if you could point me to something already written, I’d appreciate it.
