2. Question 1
Explain what is the definition of Free Software Foundations (FSF)?
The Free Software Foundation (FSF) defines free
software as software that respects users' freedom and
community. This means that users have the freedom to
run, copy, distribute, study, change, and improve the
software. The FSF promotes the development and use
of free software to ensure that users maintain control
over their computing.

3. Question 2
Justify what is the difference between GNU General Public Licenses (GPL) and
Mozilla PublicLicense.
The main difference between the GNU General Public License
(GPL) and the Mozilla Public License (MPL) lies in their
approach to copyleft and compatibility with other licenses.
GPL is a copyleft license, meaning that derivative works must
also be distributed under the same license terms, ensuring
that the software remains free. MPL is a weak copyleft license,
allowing the combination of MPL-licensed code with code
under other licenses, including proprietary licenses, without
requiring the entire work to be open source.
