Apparently, only God is compassionate and merciful these days, considering

A kernel is a piece of software that exists between the hardware and the
application software which abstracts the low level devices, handles low
level timing, and shares system resources between programs.

There are various designs that affect how this is achieved.  You may
wish to further research "monolithic kernel" and "microkernel
architecture" for more information.

The term "kernel" can apply to a general operating system architecture,
such as Linux, FreeBSD, or Windows' kernel; or it can refer to small,
homemade assembler libraries in embedded devices that manage low level
chip access.  But both offer the same function, just on a different scale.
