What is Linux?

The best one liner about Linux that I like the most is from Wikipedia. On WikiPedia it is stated that Linux is a family of free and open-source software operating systems built around the Linux Kernel.

Typically Linux is packaged in different forms which are known as Linux Distribution. These destro are available for a wide range of machines ranging from personal computers to servers and all the way up to Super-Computers. Yes, Linux target market also include Supercomputers machines. Some of the famous Linux distributions include CentOS, Ubuntu, Arch Linux, Debian, Gentoo Linux, OpenSUSE and Red Hat Enterprise Linux.

CLI is a command controled, text based interface. GUI is a graphical interface which looks alot more like other traditional OS such as Windows, Mac OS, Android and iOS. Obviously, Android, iOS, Mac and Windows are very advance Graphical interface as compared to Linux’s command based interface.
