Definition of Open Source Software
Open source software (OSS) refers to computer software that is released with a license granting individuals or organizations the right to use, modify, and distribute the software’s source code. Unlike proprietary software, which restricts access to the source code, open source software encourages collaboration and allows users to customize the software to suit their specific needs.
The Open Source Initiative (OSI), a non-profit organization, defines open source software based on several key criteria. First, the software must be freely distributed, allowing anyone to download and use it without cost. Second, the source code must be available, enabling users to study and modify it. Third, the license should allow for the redistribution of modified versions. This open collaboration and transparency foster innovation and benefit the larger software community.
Open source software has gained popularity due to its many advantages. Its flexibility allows businesses to tailor the software according to their requirements, offering cost savings and increased efficiency. Furthermore, the open nature of the development process encourages peer review, resulting in higher quality code. Users can also benefit from the vast community support and extensive documentation available for many open source projects.
One of the fundamental principles of open source software is the concept of “free as in freedom, not free as in beer.” While open source software is often available at no cost, the freedom to modify and distribute the software is paramount. This distinguishes it from freeware or shareware, which may only grant limited usage rights or require paid licenses.
The open source movement gained momentum with the creation of the Free Software Foundation by Richard Stallman in the 1980s. Stallman’s advocacy for free software led to the development of the GNU operating system, which laid the foundation for many open source projects. The term “open source” itself was coined in 1998 during a strategy session led by members of the OSI.
