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.
