Being able to simply replace a part with something else without issue is what makes Linux great.
But your distribution constantly asks you to update your kernel.
This is probably one of the most important reasons to update your kernel, as you’ll always be safer with a patched kernel.
If a hacker manages to get into the kernel, a lot of damage can be done or the system simply crashes.
Windows also has its own kernel that its operating systems use, but Linux is highly modular and therefore the kernel is more commonly discussed as a lot can be done with it.
