This document discusses the benefits of open source software over proprietary software. It provides several examples to illustrate its points: (1) reinventing the wheel can be avoided with open source code; (2) bugs can be found and fixed more quickly with many reviewers; (3) security is improved with many people reviewing code; (4) technical freedom is gained to see and modify code; and (5) personal freedom is increased to customize and distribute software. Overall, open source allows for knowledge sharing, continuous improvement, more testing and fewer bugs, increased security, and greater technical and personal freedoms.

- 26. Opensource Development Model Web Source code Community Forums Developers CVS Mailing list Contributors – testing, documentation, localisation
- 27. Opensource Business Model Service & Support Installation Training Customization Warranty Sell Distributions Facility Management
- 28. Benefits to students Study the source code and Learn programming design & technics. Understand internals of programs. Modify/enhance. Apply the design & technics in other projects. Learn to create software
- 29. Advantages to Students No need to beg industry for project. Plenty available on net. Contribute to it. Your contribution available for world. College faculty can be the guide & College itself can give the certificate. You can continue to work on the project.
- 30. Adoption of FOSS is a National Mission . The most unfortunate thing is that India still seems to believe in Proprietary solutions . In India FOSS will have to come and stay in a big way for the benefit of our billion people Dr APJ Abdul Kalam Ex. President of India
