An interesting question is: what happens when you power on the computer? Of course, the OS starts functioning. But what actions are performed exactly?

Lesson 1. The Role of the Operating SystemI had a dream to write an operating system (OS) by myself when I was a middle school student. The OS was like a Pandora's box to me, magically managing all hardware components. It would be very exciting to develop my own one.
