Linux History
In the 90s, a guy named Linus Torvalds, a Finnish student bought a 386 computer(computer with 80386 processor) and wrote a new POISX compliant kernel. He then put the source code online thinking that it will never support anything but 386 hardware. Many developers and other people accepted this kernel combined with GNU tools, and rest, it created history.
Presently, more than 90 % of supercomputers (including the top 10 ), more than half of the smartphones and more than 70 % of the web servers (including google, facebook, amazon) and several devices such as DVD players, washing machines, routers, navigation devices run on Linux. It is the most commonly used Operating system in the World.

Linux Distributions
A linux distribution is a collection of softwares( usually open source) on top of Linux kernel. A distribution ( or distro ) can bundle server software, system management tools and many desktop applications in a central secure software repository. A distro is generally furnished with a GUI (Graphical User Interface). So, they provide a similar interface, secure and easy software management and often provide a specific operational purpose. For example, Kali Linux is used for penetration testing purposes.
Popular Linux Distributions are:
- Debian
- Ubuntu
- Red Hat
