Open-Source Software (OSS) is software whose source code is made publicly accessible. This allows anyone to view, modify, and enhance it. This collaborative approach encourages innovation and rapid development as developers worldwide contribute to its improvement. OSS promotes transparency, as users can verify what the software does and ensure it is free from malicious code. The open-source model fosters community-driven support, often resulting in robust and secure software. Many popular platforms and tools, like Linux and Mozilla Firefox, are open-source, highlighting the model's effectiveness in producing high-quality, reliable software solutions.
