The kernel is a core part of the Operating System.

The kernel is the main component of an operating system which manages the operations of computer and hardware.

An Operating System has some set of software by which it interacts with the users and takes input from it.

When it gets the input, it sends it to Kernel.

Then the kernel starts working on the requirement of the users and it returns the output to the operating system once work is done.

And then the operating system presents the output to the user.

Like this it works.

Only Kernel Interacts with the resources like hardware and manages operations of memory and CPU time.
