HB Blog 123: Android PowerPoint Viewer Tutorial.

Microsoft PowerPoint is a slide show presentation program currently developed by Microsoft, for use on both Microsoft and Apple Macintosh operating systems. PowerPoint, initially named "Presenter", was created by Forethought Inc.. Microsoft's version of PowerPoint was officially launched on May 22, 1990, as a part of the Microsoft Office suite. PowerPoint is useful for helping develop the slide-based presentation format and is currently one of the most commonly used slide-based presentation programs available. Microsoft has also released the PowerPoint mobile application for use on Apple and Android mobile operating systems.

PowerPoint presentations consist of a number of individual pages or "slides". The "slide" analogy is a reference to the slide projector. Slides may contain text, graphics, sound, movies, and other objects, which may be arranged freely.

Microsoft Office PowerPoint Viewer is a program used to run presentations on computers that do not have PowerPoint installed. Office PowerPoint Viewer (or in PowerPoint 2007 and later, a link to a viewer download) is added by default to the same disk or network location that contains one or more presentations packaged by using the Package for CD feature. PowerPoint Viewer is installed by default with a Microsoft Office 2003 installation for use with the Package for CD feature. The PowerPoint Viewer file is also available for download from the Microsoft Office Online Web site. Presentations password-protected for opening or modifying can be opened by PowerPoint Viewer. The Package for CD feature allows packaging any password-protected file or setting a new password for all packaged presentations. PowerPoint Viewer prompts for a password if the file is open password-protected. PowerPoint Viewer supports opening presentations created using PowerPoint 97 and later. In addition, it supports all file content except OLE objects and scripting. PowerPoint Viewer is currently only available for computers running on Microsoft Windows.
