Some refer to this combination as GNU/Linux or LiGNUx, but it has become more common (and erroneous) to simply say Linux, with the understanding that GNU software is pretty much implied.Ĭhoosing the right distribution to download can seem a little overwhelming, as there are many options. GNU makes its way onto most distributions, which is a collection of free software.

Generally, most or all of the software included in a Linux distribution is the same way. The Linux kernel is free and open source. Such software usually includes a package manager, desktop environment, and other common tools you’d expect to find. They’re also what make each distribution unique. These additions are what make Linux usable out of the box and give the user an operating system experience.

Linux distributions, or distros, all share the same kernel but come preloaded with a slew of software and utilities. When people say “Linux,” what are they actually referring to? Linux isn’t technically an operating system itself, but a kernel that serves as the foundation for a fully packaged operating system.
