Comparison Open Source Closed Source Software
Open Source and Closed Source Software
In the realm of software development, two predominant models exist: open source software (OSS) and closed source software. These models define how software is shared, developed, and distributed, impacting its use and evolution.
Open Source Software
Open source software is characterized by its freely available source code, allowing anyone to use, modify, and distribute the software. This model is part of a larger open-source movement that promotes transparency and collaboration in software creation. The Open Source Definition by the Open Source Initiative outlines specific criteria that software must meet to be considered open source.
OSS is governed by open-source licenses which dictate how the software can be used, modified, and distributed. These licenses encourage innovation by allowing developers to build upon existing work. Many well-known projects, such as the Linux operating system and the Apache HTTP Server, are products of open-source collaboration. Additionally, there are various business models for open-source software that companies employ to generate revenue while maintaining open-source principles.
Closed Source Software
In contrast, closed source software keeps its source code hidden from the public. This proprietary model is often used to maintain control over the software's development and distribution. Companies like Microsoft and Adobe often use closed source models to protect their software from unauthorized use and to maintain competitive advantage.
While closed source software may not be freely modified or distributed, it offers benefits such as comprehensive support and stability, often backed by customer service teams. This model is prevalent in commercial software where companies seek to monetize their products through sales and licensing.
Comparison and Coexistence
Both open source and closed source software have their unique strengths and weaknesses. Open-source models foster innovation and collaboration, often resulting in rapid development and community support. Closed source models, on the other hand, provide a controlled environment that may offer enhanced security and dedicated support.
Despite their differences, open and closed source software models often coexist. For instance, the Android operating system developed by Google is open source, but it often comes bundled with proprietary closed-source software like Google Mobile Services. This hybrid approach allows developers to leverage the best aspects of both models, fostering a diverse and dynamic software ecosystem.
