What is Linux?

Linux is a free and open-source operating system that was created in 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution. A Linux distribution (often abbreviated as distro) is an operating system made from a software collection based on the Linux kernel and, often, a package management system. Distributions are maintained by individuals, loose networks of developers, volunteer organizations, and commercial entities. A distribution intended to run on servers may include more server-oriented components such as support for common administrative tasks. A distribution intended to run on desktop computers may include a windowing system, a desktop environment, and applications aimed at a general computing audience.
