9. Software Licenses
• License is permission granted by the holder of a
copyright to another to use an original work.
• A software license is a document that provides
details regarding the use and distribution of
software.
• They either prohibit or provide end users with
the right to make copies of the software.
• They classified as proprietary/ closed source,
open source software and freeware/ free
software.

10. Proprietary/ Closed Source Software
• Proprietary software, you need to purchase the license
and features are unlocked only after you purchase the
software.
• Proprietary software remains the property of its
owner/creator and is used by end-users / organizations
under predefined conditions.
• Proprietary software may also be called closed-source
software or commercial software.
• It is paid software for which the software publisher retains
intellectual property rights.
• Some examples of Proprietary software includes
Windows, MacOS, Internet Explorer, Google earth,
Microsoft Office etc.

11. Open-source Software
• The term Open Source refers to software in which
the source code is freely available for others to view,
amend, and adapt.
• It is free software in which the software publisher
releases the source code under a license.
• It grants permission to end users to redistribute
them and make modifications in the software.
• Some examples of Open source software includes
Android, Ubuntu, Firefox, Open Office etc.

12. Freeware/Free Software
• It is software that is available for free, but they are
still considered closed source or proprietary
software because their source code is not available
to the end user to make any modifications.
• Shareware is where the software is free only for
specified period, on only few features are available
for free. E.g. WinZip or MySQL.
• Then we have Freeware. These are software where
all features are available free for life. E.g. Yahoo
Messenger or Adobe PDF.

13. Open Source Software Movement
• The open-source-software movement is a
movement that supports the use of open-source
licenses for some or all software, a part of the
broader notion of open collaboration.
• It is a movement in which the source-code of
software is released to programmers in order to
make voluntary modifications and its distribution.
• Such movement lead to the development of
MediaWiki software through which Wikipedia
website is built.
