open source software

Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change and distribute the software to anyone and for any purpose. Open-source software is developed in a collaborative public manner. Open-source software is the most prominent example of open-source development and often compared to (technically defined) user-generated content or (legally defined) open-content movements. The open-source model, or collaborative competition development from multiple independent sources, generates an increasingly diverse scope of design perspective than one company development alone can sustain long term. And a report by the Standish Group (from 2008) states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers.
