C. Linux
Linux is written and distributed under the GNU General Public License which means that its source code 
is freely-distributed and available to the general public.
D. GNU GENERAL PUBLIC LICENSE: Version 2, June 1991 
Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA 
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is 
not allowed. 
Preamble 
The licenses for most software are designed to take away your freedom to share and change it. By 
contrast, the GNU General Public License is intended to guarantee your freedom to share and change free 
software--to make sure the software is free for all its users. This General Public License applies to most of 
the Free Software Foundation’s software and to any other program whose authors commit to using it. 
(Some other Free Software Foundation software is covered by the GNU Library General Public License 
instead.) You can apply it to your programs, too. 
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are 
designed to make sure that you have the freedom to distribute copies of free software (and charge for this 
service if you wish), that you receive source code or can get it if you want it, that you can change the soft-
ware or use pieces of it in new free programs; and that you know you can do these things. 
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask 
you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute 
copies of the software, or if you modify it. 
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the 
recipients all the rights that you have. You must make sure that they, too, receive or can get the source 
code. And you must show them these terms so they know their rights. 
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which 
gives you legal permission to copy, distribute and/or modify the software. 
Also, for each author’s protection and ours, we want to make certain that everyone understands that there 
is no warranty for this free software. If the software is modified by someone else and passed on, we want 
its recipients to know that what they have is not the original, so that any problems introduced by others 
will not reflect on the original authors’ reputations. 
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that 
redistributors of a free program will individually obtain patent licenses, in effect making the program 
proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone’s free use 
or not licensed at all. 
The precise terms and conditions for copying, distribution and modification follow. 
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, 
DISTRIBUTION AND MODIFICATION 
This License applies to any program or other work which contains a notice placed by the copyright 
holder saying it may be distributed under the terms of this General Public License. The “Program”, below, 
refers to any such program or work, and a “work based on the Program” means either the Program or any 
derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either
