4. Open-source software (OSS) is
computer software that is available in
source code form: the source code
and certain other rights normally
reserved for copyright holders are
provided under a software license
that permits users to study, change,
improve and at times also to
distribute the software.

7. Lets
make it
Clear
open source is a philosophy, that
promotes free redistribution and
access to an end product's design
and implementation details.
The word Free in OSS context
refers freedom not the cost

History…….
09/19/14 Presentation by Harishankar Rangaraj
10. 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
"Open Source”

11. 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
