The term “open-source software” refers to software that is released with source code that anyone can inspect, modify, and enhance. This model promotes transparency, collaboration, and community development. Open-source software can be freely used, distributed, and altered, often leading to faster innovation and problem-solving. Examples include Linux, Apache, and Mozilla Firefox. The open-source community fosters shared knowledge and encourages contributions from a diverse range of developers, which can lead to more robust, secure, and versatile software solutions.
