Defining

Copyright- when someone writes something and they have the right to share it and anyone else has the right to read and use it as well. Usually at the beginning of a book and it says all rights reserved.
At the beginning of books it will say in the first pages who the copyright is of someone.
Fair use- when someone writes something and other people have he right to use it.
Public domain- when someone writes or posts online it is shown to the world and the world can use it.  Like for example, right now someone could use these awfully defined words in their own context.
Plagiarism- when someone has written something and it is copied and pasted onto someone else's work. For example, when writing a paper I completely copy and paste someone else's paper that I found online and put my name on it even though it's not mine.
Citations- when you use a picture or quote from someone else and you're writing a paper or doing a presentation, you must give credit to the person that originally created it.
"You gave me a forever within my limited number of days." (The Fault In Our Stars, page 75, John Green)
Attributions- to chalk it all up. Like everything wrapped up all together. "I give attributions to my book that I read."
