Started as a
small project in 1991 by Linus Torvalds, Linux turned out to be a revolution in
the operating system market. Since then there is no turning back. It has grown
from a small number of files of sources code to 300+ distros. From operating
system to network storage, anti-virus to firewall, this open source software
has everything to serve an enterprise. You do not have to play any licensing
fees also.
When Linux
kernel was first launched, it had restriction to commercial activities. But
later was made available for the world for free. Torvalds then invited the
programmer to enhance the functionality of the Linux but on a condition that it
should be free. Though Linux is not much famous among the general public and
the reason behind this is that its functionality. Also it is freeware you can
not call for troubleshooting. But a large community of Linux programmer is
available on the internet who is ready to help you out.
