Creative Commons is a set of licenses that gives public permission to use and share creative works, based on the creator’s stated conditions.
Creative Commons is also an organization and a movement that allows creators to determine exactly how they want their work to be used by others by selecting a license comprised of at least one of four conditions.

Using the four different license conditions (attribution, share-alike, non-commercial, no-derivatives), you can build a Creative Commons license for your work, based on how you want others to use it.
