LINUX IS AN OPERATING SYSTEM KERNEL

Kernel is like heart of an operating system. Operating systems “operates” on hardware through kernel. Linux is based on GNU. Thus it is also called GNU/Linux.Linux is free and open source.Linux logo – The Tux

HEY, WHERE ARE THE OTHER THINGS LIKE BROWSER ON LINUX?Kernel alone is not sufficient to operate as full OS. We need file manager, browser, desktop manager etc. That’s where distributions come into play.

Linux kernel is foundation. Other applications runs on top of it.

Distributions, rather called Distros, have the same Linux kernel, but different application for everyday use.

Distros have different CLI interface, shell, desktop manager, audio player, server client, repositories etc.

THERE ARE MANY DISTROS AVAILABLE FOR US One can download a distro from internet, burn them on CD\DVD and install it on pc.

SO WHAT IS THE DIFFERENCE BETWEEN OTHER OS AND LINUX?

LINUX IS FREE AND OPEN, AS ARE MOST OF THE DISTROS

Many of us don’t know that Windows 7 Ultimate version originally costs nearly 300 US dollar per license. Where Linux is free as are most distros.

On the contrary Linux is free and open source.

One is free to copy and distribute the Linux kernel and the free distros.

LINUX IS FREEDOM, YOU HAVE THE RIGHTS OF WHAT YOU USE On proprietary OS user give up all the

rights by accepting EULA. User can not share, distribute or modify the system file.

In Linux you have the rights. You can share, distribute and mainly modify the system and distribute the MODIFIED files on Linux.

Unlike other OSs you can do whatever you want with system files and directories in Linux.

IN LINUX THERE ARE NO SECRETS

Other OS’s hide their system files and how they work. You can not modify them.

In Linux there are no secrets. You can view and modify any file of system you like. You can even delete the root directories.

LINUX IS HIGHLY CUSTOMIZABLE Linux is customizable beyond

imagination. This is the reason there are so many variations of Linux.

Linux runs on the smallest and weakest computers like watch, phones. Then it runs on huge servers, on satellites, warehouse scale computers. And last but not least, to run super computers there is only one option, LINUX!!!

LINUX IS A VERY POWERFUL OSIT HAS RARE VIRUS ATTACKS Linux is very powerful and reliable OS. It

is stable . Linux virus attacks are so rare typical user won’t experience it.

Linux supports numerous commands and it has the most number of shells.

The script language of Linux is vastly superior to other OS scripts.

So when are you switching to LINUX?
