Open source is an approach to the design, development, and distribution of software, offering practical accessibility to a software's source code. Some consider open source as one of various possible design approaches, while others consider it a critical strategic element of their operations. Before open source became widely adopted, developers and producers used a variety of phrases to describe the concept; the term open source gained popularity with the rise of the Internet, which provided access to diverse production models, communication paths, and interactive communities.
All open Source Softwares and Applications are free, and hence provide a chance to the world of ordinary people to fulfill their needs without at any cost.
Open source software (OSS) projects are built and maintained by a network of volunteer programmers. Prime examples of open source products are the Apache HTTP Server, the internet address system Internet Protocol, and the internet browser Mozilla Firefox. One of the most successful open source products is the GNU/Linux operating system, an open source Unix-like operating system.
