Free and Open Source Software (FOSS)

Free and Open Source Software (FOSS) refers to software that anyone can access, use, modify, and share freely. “Free” means no cost is involved, while “Open Source” indicates the source code—the instructions that make the software work—is openly available for review and improvement. This transparency encourages community collaboration, innovation, and customization. FOSS is often maintained by volunteers or organizations committed to openness, and it underpins many essential applications and platforms. Overall, it promotes freedom, flexibility, and continuous development in software, benefiting users and developers worldwide.
