What is OS Software (OSS)
● Software whose source code is available for modification
or enhancement by anyone.
● Programmers can use this source code to fix parts that
don't work, can add new features, can use it as a part of
their projects
● Example: LibreOffice, GNU Image Manipulation, Unix,
Android, Apache, PHP, Python, Wordpress CMS, Firefox
OS...and the list goes on
● Term coined by OSI (Open source initiative)
