From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The kernel. That's the part that is literally called "Linux", i.e. the thing that has all the drivers for your hardware and regulates of multiple applications can run at once on the same machine.
On top of that comes the GNU userland (a project started before Linux to build a free Unix), this gets a bit more fuzzy, this includes things like glibc, all the basic tools, shell, ls, tar, rm, gcc, ... It's fuzzy because it's not strictly required to run Linux. Android for example runs the Linux kernel, but has a completely different userland than a typical Linux installation, much of which use the GNU tools. And than you have things like systemd, X11, KDE, Gnome, ... that aren't really GNU userland tools, but rather important to what most people would expect from a "Linux desktop".
