Heard of MAC OS?  How about Windows?  Now have you heard of Linux?  Believe it or not, it’s an operating system that you’ve used and had no idea you did.

Linux is a free and open sourced operating system that was created by Linus Torvalds.  Open source means that the consumer could customize the code inside of their operating system.  This is a function that is not available without retribution from proprietary operating systems such as MAC and Windows.

Distributions
