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.

Includes powerful features
Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.

Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

Linux 4.8-rc1 now ready for public testing

If you're wondering what's new in the Linux kernel 4.8 RC1 release, we can tell you that over 20% of the patch consists documentation updates, 60% comes in the form of updated drivers, this time for things like GPU, sound, media (including a driver for the touchscreen controller found on the Microsoft Surface 3 tablet computer), and networking, and 15% represents architecture updates, in particular for ARM, PowerPC (PPC), x86, MIPS, and s390.

The rest of 5% is shared among core networking updates, core kernel improvements, tooling (mainly perf) changes, as well as filesystems fixes, especially for XFS. If you're an early adopter and would like to take Linux kernel 4.8 for a test drive, you can download the Release Candidate 1 milestone right now via our site or from kernel.org. Please note that this is a pre-release version, not meant to be used on a production machine.
