A kernel is a piece of software that has two primary functions:
1) abstraction layer between hardware and (user) software, so that each
user software doesn't need to know how the hardware works.
2) manage resources like memory, cpu, storage,...

This is true for any operating system, not just Linux.

To be honest, it's what I remembered after reading Modern Operating
Systems by Andrew S. Tanenbaum 2 years ago. That book may have been
published as an ebook, but I rephrased it in my own words.
