Open Source

Figure 1. Open source vs closed source.

Open Source is a way of creating new complex systems by communal creation. The process is typified by open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development, public accessibility and lack of ownership. The term was originally used in the context of software development to designate a specific approach to creating computer programs. Today, however, "open source" designates a broader set of values—whatd called "the open source way."

Open source projects are generally typified by:

• Software or other creative works that are freely available for use, modification, and distribution.
• The source code of an open source software is available for anyone to view, use, and modify.
• Open source projects are often developed by a community of volunteers and contributors.
• The open source philosophy emphasizes collaboration, transparency, and accessibility.
• Open source software is often less expensive (or free) compared to proprietary software.
• Open source licenses are used to ensure that the software remains open and that any derivatives are also open source.
• Open source software

Examples of the most popular open source software include Linux, Apache, and Firefox and is used by many companies and organizations, including IBM, Google, and the U.S. Department of Defense.
