What is Linux?

Linux is an open-source operating system that is based on the Linux kernel, first released on September 17, 1991, by Linus Torvalds. It's a Unix-like system which means it shares many characteristics with other systems derived from Unix, such as macOS and various BSD distributions. Linux is known for its reliability, security, and efficiency, which makes it a popular choice for servers, desktops, and embedded systems worldwide. Unlike proprietary operating systems, Linux is freely redistributable and can be modified by anyone, leading to a wide variety of distributions tailored for different purposes. These distributions may include a vast array of software and can offer different user interfaces and user experiences. Some of the most well-known distributions are Ubuntu, Fedora, Debian, and Red Hat Enterprise Linux.
Snippet from Wikipedia: Linux

Linux (, LIN-uuks) is both an open-source Unix-like kernel and a generic name for a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project.

Popular Linux distributions include Debian, Fedora Linux, Arch Linux, and Ubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland and a desktop environment such as GNOME, KDE Plasma or Xfce. Distributions intended for servers may not have a graphical user interface at all, or include a solution stack such as LAMP. Because Linux is freely redistributable, anyone may create a distribution for any purpose.

Linux was originally developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system. Because of the dominance of Linux-based Android on smartphones, Linux, including Android, has the largest installed base of all general-purpose operating systems as of May 2022. Linux is, as of March 2024, used by around 4 percent of desktop computers. The Chromebook, which runs the Linux kernel-based ChromeOS, dominates the US K–12 education market and represents nearly 20 percent of sub-$300 notebook sales in the US. Linux is the leading operating system on servers (over 96.4% of the top one million web servers' operating systems are Linux), leads other big iron systems such as mainframe computers, and is used on all of the world's 500 fastest supercomputers (as of November 2017, having gradually displaced all competitors).

Linux also runs on embedded systems, i.e., devices whose operating system is typically built into the firmware and is highly tailored to the system. This includes routers, automation controls, smart home devices, video game consoles, televisions (Samsung and LG Smart TVs), automobiles (Tesla, Audi, Mercedes-Benz, Hyundai, and Toyota), and spacecraft (Falcon 9 rocket, Dragon crew capsule, and the Perseverance rover).

Linux is one of the most prominent examples of free and open-source software collaboration. The source code may be used, modified, and distributed commercially or non-commercially by anyone under the terms of its respective licenses, such as the GNU General Public License (GPL). The Linux kernel, for example, is licensed under the GPLv2, with an exception for system calls that allows code that calls the kernel via system calls not to be licensed under the GPL.
