  • So basically the open source code is developed for public contribution and made for free available.

4. Difference between Open source and Close source?

      • Open source software is distributed under the licensing agreement which allow to be share, modify and view the code by other users and organization.
      • Open source slightly more user-friendly language.
      • Don’t make the mistake of assuming that OSS is always free. Many software creators release their programs free of charge but then make very good money selling services and support.

      • Closed source software can be defined as proprietary software distributed under a licensing agreement to authorized users with private modification, copying, and republishing restrictions.
