There is a book called how Linux works.

But the short answer is. Linux provides the kernel that includes a lot of functionality out of the box. Drivers so all hardware can be abstracted away, scheduling of tasks, a filesystem with privileges, processmanagement etc. This lives in the kernel.

In userland, there is more or less the GUI stuff (not entirely true). You can interact with higher privileges if you have the rights / sudo.

Linux makes you hardware run and abstracts it away in Operating System.

Long answer. Read the book. It is very good.

A friend of mine made a revamped one. Not sure if it is the same project.

Doing it for the memes. I love that man.
