Final answer:
The term for unrestricted online research output is 'open access,' which enables the free use of materials by anyone while ensuring the original creator is credited.
Step-by-step explanation:
The term for online research output that is free of any and all restrictions on access, and free of many restrictions on use, such as copyright or license restrictions, is open access. Open access materials are typically available online and can be freely used by students, teachers, and the public. These resources are often distributed under Creative Commons licenses, which allow for various levels of reuse, revision, redistribution, and retention, provided the original creators are properly attributed. Open Access is crucial for the dissemination of knowledge as it maximizes the impact of research by making it available to a broader audience, including those who cannot afford expensive journal subscriptions.
