Free Software is not only those programs whose code is open, but it represents all those that respect the essential freedoms of the user. According to the Free Software Foundation (1985), created by Richard Stallman, the four essential freedoms are:<\/span><u><\/u><u><\/u><\/p>\n<p class=\"x_m_-4643876669035784116s5\"><span class=\"x_m_-4643876669035784116s9\">&#8211; Freedom to execute the program as desired.<\/span><u><\/u><u><\/u><\/p>\n<p class=\"x_m_-4643876669035784116s5\"><span class=\"x_m_-4643876669035784116s9\">&#8211; Freedom to study and change the program.<\/span><u><\/u><u><\/u><\/p>\n<p class=\"x_m_-4643876669035784116s5\"><span class=\"x_m_-4643876669035784116s9\">&#8211; Freedom to redistribute copies.<\/span><u><\/u><u><\/u><\/p>\n<p class=\"x_m_-4643876669035784116s5\"><span class=\"x_m_-4643876669035784116s9\">&#8211; Freedom to distribute copies of their modified versions to third parties.<\/span><u><\/u><u><\/u><\/p>\n<p class=\"x_m_-4643876669035784116s5\"><span class=\"x_m_-4643876669035784116s9\">The four freedoms have to be applied in all program\u2019s code from the base to the lines that have been added later.
