What is open-source software (OSS)?

Open-source software (OSS) is software with source code that anyone can inspect, modify, and enhance. The term "open source" refers to something that can be modified because its design is publicly accessible.

Here are some key points about OSS:

  • Transparency — The source code of open-source software is available to the public. This means that anyone can see how the code works and can check for errors or security vulnerabilities.

  • Collaboration — Open-source software encourages collaboration among developers. Since the code is open, developers from around the world can contribute to the project, enhance the software, and share their changes with the community.

  • Freedom — Users of open-source software are free to run the program for any purpose, study how the program works, adapt it to their needs, and distribute copies of the original or modified software without having to pay royalties to previous developers.

  • Community — Open-source software often has a community of users and developers who offer support and contribute to the project's development. This can lead to rapid innovation and problem-solving.

  • Licensing — Open-source software is released under licenses that comply with the Open Source Definition — like the GNU General Public License (GPL), Apache License, MIT License, etc. — which typically allow for the software to be freely used, modified, and shared.

Examples of open-source software include the Linux operating system, the Apache web server, the Mozilla Firefox web browser, and the LibreOffice suite. Open-source software can be used for everything from operating systems and office productivity suites to databases and application development frameworks.
