FLOSS is an acronym standing for Free/Libre and Open Source Software -- a collection of terms encompassing various software movements and licensing styles that encourage the modification and redistribution of software source code. The term Free software refers to software that guarantees all of the four freedoms, while the term Open Source software refers to software that satisfies all 10 criteria of the Open Source definition. "Open Source" was coined by Christine Peterson as a corporate-friendly, freedom-agnostic synonym for "Free Software", and except for very minor deviations (there are only one or two minor licenses upon which there is disagreement), the two terms refer to the same set of software.
