Developed solely by Andrew S.Tanenbaum in 1987, it was used for educational and research purposes only MINIX is now available under the BSD license from April 2000 MINIX has released 5 versions of it so far 9

LaTeX,GIMP , Libreoffice , Mozilla Firefox and such companies have come up to encourage open source softwares today 11

12. Conclusion The GNU/Linux is the world’s biggest supporter of free software Richard Stallman, Linus Torvalds have contributed more than 20 years of their lifetime in order to support and bring about a change in the modern world The Free software Foundation (FSF) started by Richard Stallman today has billions of free applications contributed by millions of followers 12
