Copyright is a legal right, exclusively given to an originator, or an assignee, to print, perform, film, publish, or record artistic, musical, or literary material, and to allow others to do the same. It is considered a territorial right, meaning that the copyright does not extend beyond a specific jurisdiction.
Plagiarism is an instance or act of closely imitating, or using, the thoughts and language of another author without giving credit where credit is due. This happens when the person does not obtain permission to use the material and makes it their own. Ways to avoid plagiarism can be found here: http://en.writecheck.com/ways-to-avoid-plagiarism/
Fair use is a legal doctrine that allows copyrighted materials to be used without permission of the owner, given that the use is fair and reasonable and does not impair the value of the materials, nor curtails the profits reasonable expected by the owner.
