FOSS (Free and open source software)

Extract

[...] This ensures optimal interoperability and lack of surprises. Professionally speaking, the availability of source code provides a performance guarantee that you can not find elsewhere. In case of problems, it is always possible to get by, possibly using external expertise to adapt the software to its own needs. Finally, the availability of source code ensures absolute continuity of software. This kind of continuity cannot be ensured by any commercial company selling proprietary software. Disadvantages To be honest, free software also has disadvantages. [...]

[...] However, at the same time the rest of software sales decrease or suffer only slight increases (less than 10 LINUX The most famous open source software today is Linux. In 1991, Linus Torvalds, a young person from Finland, from the University of Helsinki, said that the acquisition of a 386 IBM as the standard operating system (MSDOS / Windows 3.1 ) did not suit him. He decided to write a new frame of UNIX for himself. To assist in this task, he appealed to the goodwill of other programmers. [...]

[...] It would be cheap for these institutions to pay for the software as they have a very large number of computer stations in all their premises. For example, the French government went to 70,000 positions using free software in 2005, and the Ministry of Culture with 1700 posts of computers using Open Office. The goal of both organizations to use software was not only because it was free, but also to adapt to it, so as to modify the incentive and consumer use. The other advantage was the security of the software because hackers still do not pirate free software. [...]

[...] its reliability (in the case of server vendors) and no license cost, thereby enabling the customer to invest the difference in associated services. A software must meet some conditions if it has to be called software . The term "free software" refers to the freedom the software provides and not the price. To understand the concept, we must think of freedom of expression. It is freedom provided to the users to run, copy, distribute, study, change and improve the software. [...]

[...] The opportunity to start with a basic source allows programmers to make developments more quickly than in a closed model. FOSS is one that will grow most rapidly at a fixed cost and will certainly be the most profitable in terms of overall cost to the community. To ensure interoperability between different stakeholders in the world of free software, each strives to meet the standards. Free software is thus the most open software, not only in terms of source code, but also in terms of file formats and communication protocols. [...]
