PowerPoint presentations consist of a number of individual pages or "slides". The "slide" analogy is a reference to the slide projector, a device that can be seen as obsolete, within the context of widespread use of PowerPoint and other presentation software. Slides may contain text, graphics, movies, and other objects, which may be arranged freely. PowerPoint, however, facilitates the use of a consistent style in a presentation using a template or "Slide Master".
The presentation can be printed, displayed live on a computer, or navigated through at the command of the presenter. For larger audiences the computer display is often projected using a video projector. Slides can also form the basis of webcasts.
PowerPoint provides three types of movements:
- Entrance, emphasis, and exit of elements on a slide itself are controlled by what PowerPoint calls Custom Animation
- Transitions, on the other hand are movements between slides. These can be animated in a variety of ways
- Custom animation can be used to create small story boards by animating pictures to enter, exit or move
