Plagiarism involves presenting another person's work or ideas as one's own without proper citation or acknowledgement. There are several types of plagiarism, including copying verbatim text, paraphrasing without citation, presenting another's ideas as your own, and submitting another's work as one's own. Plagiarism is considered a form of academic dishonesty and cheating. Various tools and websites exist to detect plagiarized content and originality through comparing submitted works to databases of existing sources. Proper citation and attribution of sources is important to avoid plagiarism when using others' work.
