Outline of free software explained

The following outline is provided as an overview of and topical guide to free software and the free software movement:

Free software  - software which can be run, studied, examined, modified, and redistributed freely (without any cost). This type of software, which was given its name in 1983, has also come to be known as "open-source software", "software libre", "FOSS", and "FLOSS". The term "Free" refers to it being unfettered, rather than being free of charge.
