Open-source software development is the process by which open-source software, or similar software whose source code is publicly available, is developed. These are software products available with its source code under an open-source license to study, change, and improve its design. Examples of some popular open-source software products are Mozilla Firefox, Google Chromium, Android, Libre Office and the Apache Open Office Suite. Open-source software development has been a large part of the creation of the World Wide Web as we know it, withTim Berners-Lee contributing his HTML code development as the original platform upon which the internet is now built.
