What is open source software? What are its examples?

 Open source software 

  Open source software (OSS) refers to software whose source code is freely available allowing users to view, modify and distribute the code. This collaborative approach encourages transparency innovation and community involvement.

The Open Source Initiative (OSI) defines specific criteria for licenses to be considered "open source" emphasizing characteristics such as free redistribution access to source code and permission for modifications.

  Features of Open Source Software

  1. Access to source code

      Users have access to the source code of the software allowing them to study, modify and enhance it based on their needs.

  2. Freedom to amend

      Users can modify the source code to customize the software or fix problems promoting flexibility and adaptability.

  3. Free Redistribution

      Open source licenses generally allow users to freely redistribute the software. This enables extensive sharing and collaboration.

  4. Community Support

     Open source projects often have a community of developers who contribute to developing testing and improving the software.

   5. Transparency

      Openness of source code promotes transparency helping users understand how software functions and ensuring that it operates without hidden functionalities.

   6. Licensing

     Open source software is released under licenses approved by OSI.
