Plagiarism is basically a form of cheating in which you present other’s ideas (work/task) as your own. The idea can be anything, a song, web page, book, television show, article etc. But still different people have different definitions regarding plagiarism. If you copy someone’s idea and you properly cited it, then it does not come under plagiarism. But if you do not mention the source (from where you copy this idea) then it comes under PLAGIRISM.
