History of Open source
Concept of free sharing information existed long before
computers, For example: Sharing of Cooking Recipe’s
In early 1960’s any computer academy who develop a
software shared its source code under the principle of
openness & co-operation
Any source code, human-readable form of software, was
generally distributed with the software itself because
Users frequently modified the software themselves,
Resolve Compatibility issue with hardware or Operating System
,
Also to fix bugs or add new functionality.
This led to a “Free Software Movement” via
World Wide Web and later termed as

6. Open Source Principles
 Open source enables us to read the code
 We can see how it’s made
 The freedom to run the program for any purpose
 The freedom to study how the program works, and
adapt it to your needs
 The freedom to redistribute copies
 The freedom to improve the program

8. Evolution of FOSS

9. FOSS – Free & Open Source
Software
 Free and Open-Source Software (F/OSS, FOSS) or
free/libre/open-source software (FLOSS) is software
that is liberally licensed to grant the right of users to
use, study, change, and improve its design through
the availability of its source code.
 In the context of free and open-source software, free
refers to the freedom to copy and re-use the
software, rather than to the price of the software.
 Free software focuses on the philosophical
freedoms it gives to users while open source
focuses on the perceived strengths of its peer-to-
peer development model.

14. Licensing Model
Any Open Source application has to be registered
and licensed by the “FSF – Free Software
Foundation” with a related distinct criteria to be
declared as Free Software
 Free Proliferate Copyrighted License – GPL & MPL
They require that any modified software and any program including this software
in a derived product must be placed under the same license
 Free Copy Left Persistent Licenses – LGPL & BSD
They contain a clause allowing users to mix the software with proprietary
software and place it under a proprietary license, on the condition that the
free module remains under a free license
 Free Non Copy Left Licenses – License Apache
Any one can transform a source code under this license without acknowledging
its original developer

15. Conclusion with a Statistics
Open Source Technology - A Boon to IT
• 54% of IT Executives said Open Source would be their
dominant server & application platform in 5 years
--- (Source : CIO
Magazine)
• Apache has 67% of Web Server market
• Linux based Servers and its supported Enterprise
applications – will be the first choice for the SME segment
