Open-source software (OSS)
is a type of computer software whose source code is released under a license in which the copyright holder grants users the rights to study, change, and distribute the Software to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. According to scientists who studied it, open-source software is a prominent example of open collaboration. The term is often written without a hyphen as "open source software".
Open-source software development, or collaborative development between multiple independent contributors, generates an increasingly more diverse scope of design perspective than any one company is capable of developing and sustaining long term. A 2008 report by the Standish Group states that adoption of open-source software models has resulted in savings of about $60 billion (£48 billion) per year to consumers.
