Open source software is software that is released with a license that allows users to freely use, modify, and distribute the software's source code. This means that anyone can access the underlying code of the software, make changes to it, and share those changes with others. Open source software is typically developed in a collaborative and transparent manner, with the goal of creating high-quality software that is accessible to everyone. Examples of popular open source software include the Linux operating system, the Firefox web browser, and the LibreOffice office suite.

Open source software is software that is released with a license that allows users to view, modify, and distribute the source code. This means that anyone can access the code, make changes to it, and share those changes with others. On the other hand, other types of software, such as proprietary software, have restrictions on viewing, modifying, and distributing the source code. Users typically need to purchase a license to use proprietary software and are not allowed to make changes to the code or distribute it without permission. Open source software promotes collaboration and transparency, while proprietary software is usually developed and controlled by a single entity.

There are several reasons why people prefer using open source software:

1. Cost: Open source software is often available for free or at a lower cost compared to proprietary software, making it more accessible to users with limited budgets.
2. Customization: Users can modify and customize open source software to better suit their specific needs and preferences, providing a level of flexibility that may not be possible with proprietary software.
3. Transparency: Open source software is developed in a transparent manner, allowing users to inspect the code and understand how the software works. This transparency can help build trust and confidence in the software.
4. Community support: Open source software is often supported by a community of developers and users who contribute to its development, provide support, and share knowledge and resources.
5. Security: The open nature of open source software allows for more eyes to review the code, which can help identify and fix security vulnerabilities more quickly than with proprietary software.
6. Innovation: Open source software encourages collaboration and innovation, as developers can build upon existing projects and share their improvements with the community.

Overall, the freedom, flexibility, and collaborative nature of open source software make it an attractive choice for many users and organizations.
