A PPT presentation is a type of presentation created using Microsoft PowerPoint, a presentation program created by Robert Gaskins and Dennis Austin at a software company named Forethought, Inc. . PowerPoint presentations work like slide shows, where a message or story is broken down into slides. A PPT presentation can be created from scratch or by using a prepared design template. Each slide can be thought of as a blank canvas for the pictures and words that help tell the story. A theme is a slide design that contains matching colors, fonts, and special effects like shadows, reflections, and more. A PPT presentation can include audio, visual, and audio/visual elements. The full form of PPT is PowerPoint Presentation.
