User Space vs Kernel Space Explained | Linux System Calls Internals | EP08
📚 Execution Awareness Series — Episode 8
User programs run in one world.
The operating system runs in another.
So what happens when your application needs memory, files, networking, or hardware access?
In this episode, we trace that transition and understand how Linux moves between user space and kernel space.
🧠 You will learn:
• What user space actually means
• What kernel space actually means
• Why applications cannot directly access hardware
This episode builds the foundation for:
Syscalls • Kernel Internals • Runtime • Linux Architecture • System Programming
