The document discusses the history and evolution of open source software. It began in the 1970s-1980s as the free software movement. Over time it evolved into both the free and open source software movements. Open source refers to software with source code that is openly available and can be modified. It offers benefits like lower costs, availability of source code, and vendor independence. Examples of widely used open source software include Linux, Apache, MySQL, PHP, and Mozilla. The document also discusses open source languages, databases, and operating systems. It provides case studies on Sahana and an IT project in Kerala, India. Challenges of open source include steep learning curves and lack of standardization. However, it provides flexibility and custom

2. HIGHLIGHTS TO TOPIC
 Openly available software movement
 Openly available and accessable
 Open source is different from traditional proprietary
in user and proprietary rights.
 Eg:-Mozilla Firefox, Google Chromium, Android and
OpenOffice.org.

3. History and Evolution
 History begins:
Years 1970s and early 1980s, were the root years of the
movement.
 Evolution: Journey from free software to open source
movement. Colaaborately known in literature as
“Free and Open Source”

4. OPEN SOURCE
 Source Code
 Free Redistribution
 Derived Works
 Non-Discriminatory
 Non-Restrictive

5. WHY OPEN SOURCE?
 Cost Effectiveness
 Availability of Source Code
 Open Standard and Vendor independence
 Reduced Maintains Cost

12. CASE STUDIES
 Sahana came into existence through the
collaborative effort of IT professionals in Sri
Lanka.
 Motive:- To provide relief to victims of the
December 26, 2004 Tsunami in Indonesia.
 Non-profit organization

13. NATIONAL
KERELA CASE STUDY
 IT at School Project
 Setup in 2001 as a project of Department of General
Education
 Diverse activities such as content development,
infrastructure deployment, satellite based education
and e-Governance are initiated.

14. Open source challenges
 Steep learning curve
 Risk of discontinued community involvement
 Nobody is really responsible in case any problem

15. STRENGTHS
 Lower costs.
 Open source provides flexibility.
 The collaborative nature of the open source
community creates software that can offer
customizability which results in relevent adoption.

16. LIMITATIONS
 People should have programming knowledge.
 Lack of standardization due to multiple
developers.
 The ultimate success has no guarantee.

17. CONCLUSION
 The open source movement has grown to become a
significant force in today's computing environment. In
some sectors of the software industry, open source
programs have become popular enough to provide real
competition to proprietary alternatives; in others, they
have emerged as the dominant standard.
