1. What is Copyright?

2. Copyright
From copyright.gov: Copyright is a form of protection grounded in the U.S. Constitution and granted by law for original works of authorship fixed in a tangible medium of expression. Copyright covers both published and unpublished works.
It is a type of intellectual property law.
A work does not have to be registered to be copyright; however, it is easier to go after someone in court if it is registered.

methods of operation
It may protect the way things are expressed.
Some things are for patents. You can patent an idea about a system which has a method of operation. However, it is not copyright if you were to write it down. The way you write it is copyright.

6. What is Free Software?
A philosophical movement that started with Richard Stallman and the Free Software Foundation (FSF, founded 1985) to stand for freedom in software development.
To protect freedoms mostly from capitalism as it keeps free software from becoming a businesses proprietary software.
This is “Free” not “Open”
Richard Stallman had an idea to make software remain free as in Freedom so that people could share their software in whatever way they choose and so that software remains free forever. It protects software from becoming proprietary.

7. What is Free Software?
The Free Software Definition defines four freedoms that must be given to users:
The freedom to run the program, for any purpose (freedom 0).
The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
The freedom to redistribute copies so you can help your neighbor (freedom 2).
The freedom to distribute copies of your modified versions to others (freedom 3).

8. What is Open Source Software?
Software who’s source code is “open” or generally free to use. A development methodology.
Free software was what it was called. Then people started calling everything Open Source after a strategy session in 1998.
That same year the Open Source Initiative started and gave a philosophical foundation to open source software by creating the Open Source Definition.
The idea is that a certain license is applied to software that gives freedom to modify, copy, and redistribute to foster development and creativity.
It is considered “a valuable way to engage with potential software users and developers, and convince them to create and improve source code by participating in an engaged community.”
OSS is “a valuable way to engage with potential software users and developers…” to enhance the source in a community. It’s about development not freedom of software.
A strategy session was done after the release of Netscape’s source code by those interested in furthering the cause of software source code that is free to re-use.
