Linux is the best-known and most-used open-source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer’s hardware.

The code used to create Linux is free and available to the public to view, edit, and—for users with the appropriate skills—to contribute. It is also incredibly customizable because not just applications, such as word processors and web browsers, can be swapped out. Linux users also can choose core components, such as which system displays graphics and other user-interface components.
