free and open-source software (FOSS) allows users and programmers to edit, modify or reuse the software's source code. This gives developers the opportunity to improve program functionality by modifying it.

The term “free” indicates that the software does not have constraints on copyrights. The term “open source” indicates the software is in its project form, enabling easy software development from expert developers collaborating worldwide without any need for reverse engineering.

Free and open-source software may also be referred to as free/libre open-source software (FLOSS) or free/open-source software (F/OSS).

description

Before 1960, most software was openly accessible and free because software tools required a relatively simple development effort. As the complexity of software applications grew, this led to greater software package development efforts, making software licensing a market trend. Eventually, developers found techniques to avoid multicomputer software use, such as use of product keys and Internet activation. With the widespread use of the Internet, these techniques became essential for developers to regain profit from their efforts.

FOSS surfaced as a result of a need for free, collaborative effort in complicated and expensive projects. Today, many FOSS projects are available for active developers.\

free source

Richard Stallman's Free Software Definition, adopted by the Free Software Foundation (FSF), defines Free software as a matter of liberty not price,[11] and it upholds the Four Essential Freedoms. The earliest known publication of the definition of his free software idea was in the February 1986 edition[12] of the FSF's now-discontinued GNU's Bulletin publication. The canonical source for the document is in the philosophy section of the GNU Project website. As of August 2017, it is published there in 40 languages.[13]

Four essential freedoms of Free Software To meet the definition of "Free software" the FSF requires the software's licensing rights what the FSF respect the civil liberties / human rights of what the FSF calls the software user's "Four Essential Freedoms".[14]

The freedom to run the program as you wish, for any purpose (freedom 0). The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. The freedom to redistribute copies so you can help others (freedom 2). The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.[14]

open source

The Open-source software Definition is used by the Open Source Initiative (OSI) to determine whether a software license qualifies for the organization's insignia for Open-source software. The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens.[15][16] Perens did not base his writing on the Four Essential Freedoms of free software from the Free Software Foundation, which were only later available on the web.[17] Perens subsequently stated that he felt Eric Raymond's promotion of Open-source unfairly overshadowed the Free Software Foundation's efforts and reaffirmed his support for Free software.[18] In the following 2000s he spoke about Open source again.[19][20]
