Linux

Linux is an open source operating system developed by Linus Torvalds as a version of UNIX that could run on a home computer. He patented Linux in 1991, and then made the system and its code available to others, free of charge, over the Internet. He licensed the system in such a way that anyone can copy and use it, but any improved versions a user creates must be made available to others under the same term, so this was under the GNU GPL. This was more than enough to make the computer programmers from all over the world to flock and make additions and improvements. Today, Linux is considered to be a faster, safer operating system.
