Linux history

The Linux kernel is created by Linux Torvalds as a personal project in 1991, then in December 1992 it joined the GNU Operating System which is Unix-like operating system that was created to be an open source and free software.

The GNU project provides a collection of free applications, libraries, and developer tools that are available on many Linux distrubutions. That is why it is also called: GNU/Linux instead of just Linux, but the right name to describe the whole operating system (OS) is Linux distribution, or Linux distro as a short name, but most people call it Linux which is unaccurate.

Linux (kernel) is maintained by Linus Torvalds and many collaborators, and The Linux kernel is sponsored by The Linux Foundation, and companies like: Google, and Redhat.
