Open-source is a term used to describe software that is made freely available, with the source code open for anyone to view and modify. The source code is usually shared publicly on platforms such as GitHub, allowing developers to collaborate on projects and build upon each other's work. Open-source software can be used, modified, and redistributed freely, making it a great resource for developers who are looking to learn or create new projects.
