<human>:  Can you explain the difference between plagiarism and copyright infringement?
<bot>: Plagiarism is the act of taking someone else's work, either writing or ideas, and passing them off as one’s own. Copyright infringement, on the other hand, occurs when a person uses a substantial part of a copyrighted work without permission or exceeds their limits of fair use. This is a legal issue that can have serious consequences, both in terms of the law and financially.
