Linux is a family of open-source operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a form known as a Linux distribution for both desktop and server use.
Linux distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Linux distributions also include one or more desktop environments and a suite of applications. Popular Linux distributions include Debian, Ubuntu, Fedora, CentOS, and Red Hat Enterprise Linux (RHEL).
Linux is known for its stability, security, and flexibility. It is widely used as an operating system for servers, as well as for desktop computers, smartphones, and other devices.
