HISTORY
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”

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

Evolution of FOSS

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.
