Copyright is what you use when you don't want someone to steal or take credit of your work. You are not allowed to use copyrighted work unless you are a student or a teacher and you are using it for educational purposes, but there are still some restrictions like you can only use 30 seconds of a song. You still have to credit the author or artist though. Anyone can use work in the public domain freely without having to give credit. Plagiarism is using a copyrighted work without permission which is illegal and can result in you going to jail and possibly pay a fine.
