What is Linux Kernel?
The Linux kernel is an operating system kernel that is defined as Unix-like in nature. It is used in different operating systems, mostly in the form of different Linux distributions.
The Linux kernel was the first truly complete and prominent example of free and open source software, which led to its widespread adoption and contributions from thousands of developers.
The Linux kernel was developed by Linus Torvalds, a student at the University of Helsinki in Finland. It has quickly gained ground as programmers adapted source code from other free software projects to extend the functionality of the kernel.
Torvalds started with a task switcher written in assembly language 80386 and a terminal driver, and then put it in the Usenet group comp.os.minix. It was quickly adapted by the MINIX community who contributed insights and code to the project.
The Linux kernel grew in popularity because the GNU's own kernel, the GNU Hurd, was unavailable and incomplete, and the Berkeley software operating system distribution (BSD) was still fraught with legal problems. Linux 0.01 was released on September 17, 1991 with the help of the developer community.
