About This Course

Your operating system is the most sophisticated piece of software most people will never think about. It manages every program running on your computer, controls access to memory, handles files, schedules CPU time, and coordinates hardware — all simultaneously.

This course teaches OS concepts with real-world examples from Linux, Windows, and macOS. Every abstract concept — process scheduling, virtual memory, deadlocks — is connected to something concrete you encounter every day. By the end, you will understand what happens when you run a program, why your computer slows down, how memory works, and what a file system actually does.
