Access to the source code is a precondition for this. By doing this, the whole community has a chance to benefit from changes made by other users. the freedom to distribute copies of modified versions to others.the freedom to redistribute copies so users can help others.Access to the source code is a precondition for this the freedom to study how the program works, and change it so it does the computing as the user wishes.the freedom to run the program, for any purpose.4 freedoms conferred to the users define free software :
