OSS Software, or Open Source Software, refers to computer programs whose source code is made available to the public. This means anyone can view, modify, and distribute the software freely. Popular examples of OSS include Linux, Apache, and Mozilla Firefox. The main advantage of OSS is that it encourages collaboration and innovation among developers. Users can customize the software to meet their specific needs, and the community often helps improve security and functionality. Additionally, OSS can reduce costs for individuals and organizations since it is typically available at no charge.
