The primary system tools and libraries sourced from GNU Project, hence the nomenclature GNU/Linux (GNU Toolchain over Linux Kernel). The license for the Linux kernel the GPL v2 license.

There are many different Linux Distributions (sometimes shortened to distro), which consist of software applications packaged and provided with the Linux kernel, being Slackware the oldest active distro and Debian, Red Hat and CentOS among the most used on Internet servers¹.

The Linux kernel is commonly run on servers but is highly portable and used in a variety of applications, from wireless routers and cell phones to clusters and supercomputers with thousands of nodes and processors.
