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. 🕒 Timestamps 0:00 – Intro: Why Kernels Matter More Than You Think 0:44 – What Is a Kernel?
