The cc0 is the acronym of creative common zero licenses. It is basically an international organization that gives free license to the creator for making their work available to anyone in the world.
Through this license the creator allows others to use the work without any copyright issue under certain circumstances.
However, every creative commons licensor makes sure the licensor gets the acknowledgment for the work they deserve.
TYPES OF CC LICENSE
There are six different types of cc licenses. Each of them allows the public to use the material in different ways.
Attribution; cc By
This license allows others to expand, remix, modify, and develop upon your work, even commercially, as long as they credit you for the actual work. This is the most accommodating of the licenses given. Approved for maximum distribution and use of licensed materials.
Attribution – ShareAlike; CC BY-SA
This license permits others to alter, remix, and develop upon your work even for commercial purposes, as long as they acknowledge you and license their novel productions under identical terms. This license is oftentimes associated with “copyleft” free and open-source software licenses.
Attribution-NoDerivs CC BY-ND
This license permits for redistribution, commercial and non-commercial, as long as it is carried along unmodified and in whole, with acknowledgment to you.
Attribution-NonCommercial CC BY-NC
This license allows others to remix, modify, and grow upon your work non-commercially, and although their latest works must also credit you and be non-commercial, they don't have to license their derived work on identical terms.
Attribution-NonCommercial-ShareAlike CC BY-NC-SA
This license allows others to remix, modify, and develop upon your work non-commercially, as long as they acknowledge you and license their latest works under the same terms.
Attribution-NonCommercial-NoDerivs CC BY-NC-ND
This license is the most limiting of our six chief licenses, only letting others download your creation and share them with others as long as they acknowledge you, though they can't modify them in any condition or utilize them commercially.
