Created by a Finnish student Linus Torvalds in 1991, the project was initially (still today) to create a free operating system based on kernel.
As comparison, the Windows OS is based on NT Kernel and the Apple OS is based on Darwin Kernel.
Ubuntu, one of many Linux distros, became very popular, thanks to its very easy-to-use approach and versatile uses.
13 years of improvements from the community and overseen by the software company Canonical ( Private and based in UK) created the increasing interest of the IT business world.
Core Philosophy:
-Free of charge Distribution for public and enterprises
-Fully support by the company Canonical
-Core applications free, improved by community and open source
