"Free and open-source software" (FOSS) is an umbrella term for software that is simultaneously considered both free software and open-source software.
The free software movement and the open-source software movement are online social movements behind widespread production and adoption of FOSS, with the former preferring to use the terms FLOSS or free/libre.įurther information: Alternative terms for free software
Free-software licenses and open-source licenses are used by many software packages. Free and open-source operating systems such as Linux and descendants of BSD are widely utilized today, powering millions of servers, desktops, smartphones (e.g., Android), and other devices. Other benefits of using FOSS can include decreased software costs, increased security and stability (especially in regard to malware), protecting privacy, education, and giving users more control over their own hardware. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.įOSS maintains the software user's civil liberty rights (see the Four Essential Freedoms, below).
