Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Distributed in multiple stable branches

Once should not be confused by the many stable branches of the Linux kernel, as they are available for different purposes. For example, there are several LTS (Long Term Support) branches that can be used to deploy very stable Linux operating systems.

These days, major Linux distribution developers provide users with optimized kernel packages for different purposes. However, advanced users can configure, compile and install their own kernels directly from the source packages at any point (all you need is a supported GCC compiler).

The heart of a Linux distribution

The Linux kernel is the heart of a Linux distribution. If you are a long time Linux user, you may have stumbled across upgrades to the default Linux kernel packages, which lead to better support for certain hardware components or peripherals.
