Copyright is very basically the right to stop somebody else copying another person`s creative work. It is an exclusive right which belongs only to the owner of the creative work. The term `piracy`, as it applies to copyright infringement, is a colloquialism that was used historically to describe copyright infringement. The person stealing the creative work belonging to another was termed a `pirate`. Therefore the stealing on the internet of copyright work that belongs to another is colloquially known as `Online Piracy`. Copyright infringement is the same thing as `Online Piracy`; it’s just the formal way to describe the theft of another person`s creative work.
