Technically, Linux is only a kernel. The operating system we run is Ubuntu, or Mint, or Debian etc.

  • Linux can therefore be thought of as a family of operating systems, all connected by the fact that they all use the Linux kernel to perform backend functions.

The Linux kernel is versioned like this:


  • The first 3 bytes are semver.
  • 200 refers to bug fixes and patches in this release.
  • fc29.x86_64 refers to the distribution, here 64 bit version of Fedora 29.
