Open source software is like a digital community project. Imagine a group of volunteers coming together to build a tool that can be used by anyone, for any purpose. These volunteers (developers) work on the software without the aim of making money, but to make it better and freely available to all. Open source software is often reliable, secure, and can be customized to suit individual needs.
