Open source is a development methodology that makes an application's source code available to anyone. In software development, open source lends itself to peer development and collaboration because software source code is developed concurrently by many people. This approach is the direct opposite of the structured, controlled models of development such as the waterfall model.
Because the open-source process is collaborative and transparent, proponents contend that it delivers qualitative, reliable, flexible and less costly software than software developed using more traditional methods. Open source also encourages wide adoption of software because it is not associated with a specific vendor. Popular examples of open-source software include: Mozilla Firefox (www.mozilla.com) Linux (www.linux.org)
Apache HTTP Server (http://httpd.apache.org/) The Internet address system, Internet Protocol (IP).
