What is the free software?
The meaning of free software derives from the principles of freedom of ideas and information exchange. In the scientific discipline the principle of free information exchange is highly considered. In fact this principle is usually seen to be linked to the importance of the extraordinary growth of knowledge in the last 3 centuries.
The freedom of idea exchange is not only characterised by practical aspects, it is even the basic condition for freedom of thought and action. Like the ideas the software is immaterial, and can be copied and sent in a simple way. Everyday like the ideas, the softwares give their influence in social background, deterrminating etical,economical and politcals effects.
Richard M. Stallman, in the early 1980s, introduced the meaning of free software.The definition that Stallman gave has since been viewed as the main definition of free software and it is characterized by 4 points of liberty. These are as follows;
Liberty0 (or main freedom)
The liberty to run the programm for every aim without limit in its usage
Liberty1
The liberty to study how the program works,and taylor it for every request
Liberty2
The liberty to spread between people copies of the program
Liberty3
The liberty to impower the program and,and to destributed its apgraded versions.

Most of the commonly used licences are property licenses. It means that they can not be considered as free software because they don’t respect the 4 previous caracteristics. In a lot of instances these licenses do not allow the users to copy or modify the program.
Very often if the program is istalled on the computer, the licence doesn’t allow the customer to install the same program on a laptop or in another machine i.e. to use the program outside of the home building;if the program is used in a company, the licence doesn’t allow the user to istall the program on any other computers, even if the the already licensed computer breaks down and no longer works.
The GNU project licence, GNU GPL, on the other hand,
