Open Source Software is computer software which is available in the form of source code by which source code and other rights that are typically kept back for copyright holders are supplied within a software license that allows users to improve, change, and study the software. There is open source software that is accessible in a public domain. The development of open source software often takes place in a public teamed manner. This software is the most well-known open source development example and is typically contrasted with open content movement or user generated content. Standish Group reported that the use of models of open source software has resulted in a $60 billion annual savings to consumers.
There have been barriers with open source software adoption by enterprises. These barriers are based on the notion that open source licenses do not have a long-term roadmap, do not have the velocity to change, lack formal training and support, and are viral. Most of these barriers are related to risk.
Open source software projects are maintained and erected by volunteer network programmers. Some examples of open source products include Mozilla Firefox (internet browser), osCommerce which is the ecommerce platform, and the Apache HTTP Server. One of the most prominent open source products is known as the GNU/Linux OS (operating system). The standards of open source are not just associated with open source software. An example of this is how Microsoft has united the discussions concerning open source with the adoption of Open Document format, as well as developing Office Open XML which is another open standard.
An open source license spells out the obligations and rights that a licensor permits to a licensee. With an open source license a licensee has the right to redistribute, modify and copy source code or content.
