3.  Linux is a Unix-like operating system assembled under the
model of free and open source software
 Linux was mainly programmed in C and Assembly
languages
 The development of Linux started in the early 80’s when
Richard Stallman started the GNU project
 Linux was first originally developed as a free operating
system for Intel x86 processors

4.  The Unix operating system was conceived and implemented
in 1969 at AT&T’s Bell Laboratories in United States
 Was first released in 1971 and was initially entirely written
in assembly language
 Later was written in C language by Dennis Ritchie
 Unix grew quickly and became widely adopted in
educational institutions and businesses

5.  The GNU project started in 1983 by Richard Stallman
 Had
the goal of creating a “Complete UNIX-compatible software
system”
 In October 1985 Richard Stallman started the free software
foundation that even today exists for open source and free
software

8.  BSD stands for Berkeley Software Distribution. Also known as the Berkeley Unix
 This was developed by the California University in the late 80’s
 BSD is another UNIX-like operating system just like Linux though released after Linux


9.  An abridged 12,000 lines of source code in C. MINIX is another UNIX-like OS based
on micro kernel and inspired by Linux
 MINIX stands for Mini Unix. 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

10.  Tux was designed by Larry Ewing in 1996
 Tux the penguin is generally believed to be the mascot of Linux
 Many video games for Linux were made
on Tux like Super Tux, Super Tux Kart etc
 Various other mascots like Tuz were used
throughout the past few years in order to
promote Linux

11.  Today more than 90% of the worlds fastest super computers use a version of Linux as
the OS
 Distributors like Ubuntu, Fedora, Red Hat, MintPPC, LiMux, Kanotix etc. Have come
up with different Linux shells like GNOME, UNITY, Cinnamon, Xfce, Trinity etc
 To improvise and attract more people to it. LaTeX,GIMP, Libreoffice, Mozilla Firefox
and such companies have come up to encourage open source softwares today

12.  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
