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. open-source software operating systems built around the Linux kernel. Typically, Linux is packaged in a form known as a Linux distributionfor both desktop and server use.
