Open Source
Open source was originally traced back to so-called open-source software in which the source code is made publicly available. This allows third parties, for example other developers, to view the source code, modify it and improve or adapt the corresponding open-source software. As a rule, software with an open-source license is free of charge. In the case of open-source software, the software is usually developed by several developers within a community and checked for errors by peer reviews. Open-source software is usually cheaper, much more flexible and has a higher life cycle than commercial software from companies or individuals. Most open-source software projects use GitHub as a publishing platform. With GitHub one makes use of so-called repositories. One of the most popular open-source software projects is Linux.
