A little about Linux

Many of my friends have been asking about how to use Linux, well for programmers you have to learn to use the terminal, which is command prompt in windows, for daily users you don't require to learn it.

             However, Linux is not for daily users, it is for users who want a flexible operating system, Linux is easy to operate once learned, Linux operating system is actually free of cost, it is a Unix like operating system and a free and open source software, Linux is a operating system kernel, kernel is the heart of the operating system, Linus Torvalds released the first one on 5th October of 1991, Linux has a great advantage that it provides greater security when compared to other operating systems, the Linux is available under Ubuntu, Fedora for free, Redhat sells Linux OS to companies, many of the supercomputers of the present day work on Linux, Linux is registered under GNU general public license, which makes it open source, learning Linux is fun and useful, kernel is the bridge between applications and actual data processing done at hardware level, Linux kernel is widely used in the android devices, the mobile phone operating system, all license free packages, softwares are mostly are based on Linux.

               If you want to use a Linux operating system, you can download one at this link Ubuntu desktop OS, the link gives you the Ubuntu Download web page.
