In PowerPoint, as in most other presentation software, text, graphics, movies, and other objects are positioned on individual pages or "slides". The "slide" analogy is a reference to the slide projector, a device which has become somewhat obsolete due to the use of PowerPoint and other presentation software. Slides can be printed, or (more usually) displayed on-screen and navigated through at the command of the presenter. Transitions between slides can be animated in a variety of ways, as can the emergence of elements on a slide itself. The overall design of a presentation can be controlled with a master slide; and the overall structure, extending to the text on each slide, can be edited using a primitive outliner.

Presentations can be saved and run in any of the file formats : the default .ppt (presentation), .pot (template) or .pps (PowerPoint Show).
