Linux  a Unix-like computer operating systems based on the Linux kernel.

Distros:
There are many different versions of Linux. Unlike other commercial operating systems that are controlled by one company, Linux is free to distribute and use. So, in the Linux world, there is a situation unlike what occurs in the proprietary operating system world: a number of companies, organizations and individuals have developed their own "versions" of the Linux operating system, known as distributions or Distros.
