Portal:Free and open-source software/Introduction

Free and open-source software (FOSS) is software that is distributed in a manner that allows its users to run the software for any purpose, to redistribute copies of it, and to examine, study, and modify, the source code. FOSS is also a loosely associated movement of multiple organizations, foundations, communities and individuals who share basic philosophical perspectives and collaborate practically, but might diverge in detail questions.

The FOSS movement inspired the creation of other movements, such as open access, open hardware, open content, free culture, open standards, and many more.
