Linux Kernel Architecture
The Linux kernel is the operating system kernel used by the Linux family of Unix-like operating systems.It is a prominent example of free and open source software.
The Linux kernel is released under the GNU General Public License version 2 (GPLv2) (plus some firmware images with various non-free licenses), and is developed by contributors worldwide. Day-to-day development discussions take place on the Linux kernel mailing list.
The Linux kernel was initially conceived and created in 1991 by Finnish computer science student Linus Torvalds. Linux rapidly accumulated developers and users who adapted code from other free software projects for use with the new operating system.The Linux kernel has received contributions from thousands of programmers.All Linux distributions released have been based upon the Linux kernel.
