A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted work.

A CC license is used when an author wants to give people the right to share, use, and build upon a work that they have created.

CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of their own work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.

Royalty-free, or RF, refers to the right to use copyright material or intellectual property without the need to pay royalties or license fees for each use or per volume sold, or some time period of use or sales.

The term public domain has two senses of meaning.

Anything published is out in the public domain in the sense that it is available to the public.

Once published, news and information in books is in the public domain, although they may also be copyrighted.

In the sense of intellectual property, works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, or are inapplicable.

For example, the works of Shakespeare and Beethoven, and most of the early silent films, are all now in the public domain by either being created before copyrights existed or leaving the copyright term.

Examples for works not covered by copyright which are therefore in the public domain, are the formulae of Newtonian physics, cooking recipes, and all software before 1974.

Examples for works actively dedicated into public domain by their authors are reference implementations of cryptographic algorithms, NIH's ImageJ, and the CIA's World Factbook.

The term is not normally applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission".

Commercial software, or seldom payware, is computer software that is produced for sale or that serves commercial purposes.

Commercial software can be proprietary software or free and open source software.

A license or licence (American and British English spelling differences) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit).
