Скачать или смотреть How OS Architecture Works

🧠 Ever wondered what happens after you click an app icon?
Why do your programs suddenly freeze, or your fan spins like crazy?

In this video, we break down the modern operating system architecture, from User Space to Kernel Space, and explain how components like memory managers, schedulers, and device drivers work together.

But we don’t stop there — we compare Windows, Linux, and macOS to show how each system designs its kernel, handles system calls, and manages hardware communication.

📌 Topics Covered:

User Mode vs Kernel Mode
System Call Mechanism
Virtual Memory & Device Drivers
Hybrid Kernel vs Monolithic vs Microkernel
Why Windows puts GDI in the kernel?
How macOS uses XNU and Mach?
Why Linux is loved by developers?
