I'm new to coding and trying to understand the concept of a kernel in operating systems. Can someone explain what a kernel is and whether I can access it through system files? I feel like I'm missing something basic here!

The kernel runs directly on the hardware, allowing all user programs to function properly. You can access it through virtual files in Unix/Linux, like in `/proc` or `/sys`, where you can get information about running processes and memory without directly accessing the kernel itself. Even simple file operations interact with the kernel since they require its permission to be executed!
In short, the kernel is the part of the operating system that has complete access to your hardware. It's like the brain that can directly communicate with the physical components of your computer, like memory and devices. Without it, other software wouldn't be able to function properly.
Thanks for that! I googled and ended up with popcorn kernels instead! This programming stuff is a bit overwhelming.
The kernel is essentially the software layer that manages everything on your computer. Think of it as a city managing all the different services that run on computers. It orchestrates user programs and protects them, ensuring that one can't interfere with another by providing isolated memory spaces. If a program misbehaves, the kernel can shut it down. It's a crucial part of making sure everything operates smoothly!
So, if I understand correctly, the kernel is loaded from a file during boot? And when we run shell commands, that's how we communicate with it?
