What are open-source operating systems?

Open-source operating systems are defined by their accessibility of source code, which is available for anyone to view, modify, and distribute. This characteristic fosters collaboration and innovation within the community, empowering users not only to use the software but also to adapt it to their own needs or contribute improvements. Open-source projects often thrive on community engagement, where developers from various backgrounds can contribute to the development and enhancement of the software.

The other options do not accurately describe open-source operating systems. For example, the idea that open-source systems can only be modified by the original creator contradicts the fundamental philosophy of open-source, which is rooted in user empowerment and collaborative efforts. Similarly, a description of operating systems with restricted access to source code inherently misrepresents the open nature of open-source software; they are defined precisely by their openness, which allows for transparency and communal growth. Lastly, characterizing open-source systems as commercial and requiring a license to use is inaccurate, as many open-source operating systems are freely available and operate under licenses that promote user freedom and sharing.
