Free and Open Source Software (FOSS)?
· Open source software is software with source code that anyone can inspect, modify, and enhance.
· “Source code” is the part of software that most computer users don’t ever see; it’s the code computer programmers can manipulate to change how a piece of software—a “program” or “application”—works.
· Programmers who have access to a computer program’s source code can improve that program by adding features to it or fixing parts that don’t always work correctly.
· It gives developers the opportunity to improve program functionality by modifying it.
· It doesn’t mean software is free of cost
The term “free” indicates that the software does not have constraints on copyrights.
Closed source software
Some software has source code that only the person, team, or organization who created it—and maintains exclusive control over it—can modify. People call this kind of software “proprietary” or “closed source” software.
Only the original authors of proprietary software can legally copy, inspect, and alter that software.
In this case one does not purchase the software, but only pay to use it.
Microsoft Office and Adobe Photoshop are examples of proprietary software.
