Creative Commons has its foundations in Copyright and has three layers, and six different types of licenses.
CC License Elements
Creative Commons licenses provide creators with a greater degree of flexibility in making their works reusable and sharable. To abide by Copyright Law, all works used with Creative Commons licenses must provide credit to the licensor and the location of the work.
The following are the four elements that compose a Creative Commons license which can be combined in several different ways to create six unique Creative Commons licenses.
Attribution or "BY" symbol. This provides the most freedom as it states that the work
should include attribution. All CC licenses must include this condition.
NonCommercial or "NC" symbol. The work is to be used for
noncommercial purposes.
ShareAlike or "SA" symbol. Adaptations must be licensed under the
same license.
NoDerivatives or "ND" symbol. Reusers cannot share adaptations
of the work.

Since works in the public domain are no longer protected by intellectual property laws such as copyright, trademark, or patent laws and are now owned by the public rather than an individual author or artist, CC licenses are not applicable to this works. Creators, however, can choose to place their work in the public domain by using Creative Commons licenses such as the CC0 (CCZero) Public Domain Dedication.
A CC0 license basically means "No Rights Reserves" and allows the copyright holder to release their work in the public domain without any restrictions. It provides the choice to opt-out of copyright and database protection, and the exclusive rights automatically granted to creators.
Limitations & exceptions allow the public to use content without permission. In many countries these include permission for parody, criticism, access for visually impaired, and libraries. Many educational and classroom use falls under fair use, but there are many use cases that can be fair.
