What an Operating System is
Anatomy of an OS
- User Interface: What you interact with. Window Managers for instance.
- Application Layer: What developers use to make software run.
- Kernel: The Core of the OS. Makes communication between hardware and applications sane.
- Hardware: What does the actual computations. The thing your keyboard is plugged into.

OSDev.org is a wiki dedicated to helping people develop their own operating systems. It's a big leap from this lesson, but great if you're interested in learning the nitty-gritty.
Operating Systems Design and Implementation by Andrew S. Tanenbaum is a classic in the world of OS Development. It's also a big leap, but can teach you more about how Operating Systems work than you ever thought there was to know.
