Kernel in Operating System: The Secret Power Inside Every Computer System Design!

The Kernel in Operating System is the core — the invisible but essential layer that powers everything from your apps to your hardware.

In this breakdown, I'll explain:
✅ What the kernel actually is
✅ How it handles CPU time-slicing, memory, files, and hardware
✅ The difference between monolithic and microkernels
✅ Why engineers still obsess over kernel design
✅ Where else you’ll find “kernels” — like GPUs and quantum computing

Whether you’re a systems engineer or just curious how your computer boots, this video walks you through the system design and inner workings of the kernel with clear analogies and visuals.
