Presentation is the process of presenting the content of a topic to an audience. Presentation software, such as Impress, Beamer, Apple Keynote or Microsoft PowerPoint, is often used to generate the presentation content. As a form of communication, a presentation is usually 10-30 minutes long, but can take longer in special cases.
