Creative Commons (CC) is a system of Copyright licensing that allows the legal use and reuse of media. When you see a Creative Commons license, it means that the copyright holder of that work has decided to share their work with you—and with everyone else.

The Creative Commons (CC) licences are an easy-to-understand set of licences which allow a tiered set of usage so that creators get acknowledged for their work and the integrity of the work is protected. All CC licences have attribution at their core.
The licences are:
Attribution (CC-BY)
This is the least restrictive of the Creative Commons licences. This one means that in order to use your work, people just have to acknowledge that you were the original creator.
Attribution-Share Alike (CC-BY-SA)
The next layer up is a Share-Alike licence, which means that people can modify your work, even for commercial purposes, as long as they acknowledge you as the original creator. They do not have to pay to use your work under this licence, but they do have to licence their own creation under the same terms (so, use the CC-BY-SA licence). Wikipedia use this licence.
Attribution-No Derivatives (CC-BY-ND)
Under this licence, people can use your work (including for commercial purposes), but they cannot share it in its modified form.
Attribution-Non-Commercial (CC-BY-NC)
Non-commercial licences are just that - people can use your work, as long as they're going to make it freely available and not use it for commercial gain. However, they don't have to licence their new work on the same terms.
Attribution-Non-Commercial-Share Alike (CC-BY-NC-SA)
This licence allows people to use and adapt your work, as long as they make it freely available and do not use it for commercial gain. People must also acknowledge you as the original creator, and licence their own creation under the same terms.
Attribution-Non-Commercial-No Derivatives (CC-BY-NC-ND)
This is the most restrictive of all the CC licences. Basically, new users have to acknowledge you as the original creator, not use your work for a commercial purpose, and not share it in its modified form.
Attribution-Public Domain (CC0)
This is s a public dedication tool, which allows creators to give up their copyright and put their works into the worldwide public domain.
