Defining a PowerPoint Presentation - dummies

Defining a PowerPoint Presentation

By Doug Lowe

PowerPoint is similar to a word processor, except that it’s geared toward creating presentations rather than documents. PowerPoint presentations consist of one or more slides. Each slide can contain text, graphics, and other information. You can easily rearrange the slides in a PowerPoint presentation, delete slides that you don’t need, add new slides, or modify the contents of existing slides.

You can use PowerPoint to create and present your presentations or you can use one of the following types of media to show your presentations:

  • Computer monitor: Your computer monitor, either a CRT monitor or an LCD, is a suitable way to display your presentation when you’re showing it to just one or two other people.

  • Computer projector: A computer projector projects an image of your computer monitor onto a screen so large audiences can view it.

  • Overhead transparencies: Overhead transparencies can be used to show your presentation using an overhead projector.

  • Printed pages: Printed pages allow you to distribute a printed copy of your entire presentation to each member of your audience.

  • 35-mm slides: For a fee, you can have your presentation printed onto 35-mm slides either by a local company or over the Internet.

A presentation is to PowerPoint what a document is to Word or a worksheet is to Excel. Each presentation that you create is saved on the hard drive as a separate file.

PowerPoint 2007 presentations have the extension .pptx added to the end of their filenames. For example, Sales Conference.pptx and History Day.pptx are both valid PowerPoint filenames. When you type the filename for a new PowerPoint file, you don’t have to type the .pptx extension, because PowerPoint automatically adds the extension for you.
