What is Microsoft PowerPoint exactly? And what exactly do u do with it? I have microsoft powerpoint 2003.

Microsoft PowerPoint is a presentation program developed by Microsoft for its Microsoft Office system. Microsoft PowerPoint runs on Microsoft Windows and the Mac OS computer operating systems.

It is widely used by business people, educators, students, and trainers and is among the most prevalent forms of persuasion technology. Beginning with Microsoft Office 2003, Microsoft revised branding to emphasize PowerPoint's identity as a component within the Office suite: Microsoft began calling it Microsoft Office PowerPoint instead of merely Microsoft PowerPoint. The current version of Microsoft Office PowerPoint is Microsoft Office PowerPoint 2007. As a part of Microsoft Office, Microsoft Office PowerPoint has become the world's most widely used presentation program.
