A PowerPoint presentation is a digital slide presentation created in Microsoft PowerPoint. It allows presenters to display information such as text, images, videos and audio to engage an audience. The purpose of a PowerPoint presentation is to present information to an audience in a concise visual manner that facilitates comprehension and faster decision making. Effective PowerPoint presentations use visual elements like images and minimal text over sentences and paragraphs to make the message memorable. Presenters should follow design best practices such as limiting each slide to 6 topics, using consistent fonts and colors, and only including images that complement the message rather than for decoration.
