Explain how you would use the principles of fair use and creative commons(cc) in a presentation.

Fair use is a copyright principle based on the belief that the public is entitled to freely use portions of copyrighted materials for purposes of commentary and criticism. For example, if you wish to criticize a novelist, you should have the freedom to quote a portion of the novelist’s work without asking permission. Absent this freedom, copyright owners could stifle any negative comments about their work.
