What is Microsoft PowerPoint Viewer?
Microsoft Powerpoint, a presentation software, is one of the three cornerstones of the Microsoft Office productivity suite, and one of the founding applications, which includes Microsoft Word (a word processor) and Microsoft Excel (a spreadsheet program).Powerpoint’s concept revolves around the idea of “slides”. These are individual, and sometimes independent pages, which are anchored on the idea of a slide projector; in effect, Powerpoint is a digital version of this device, and it can create the slides via a combination of text, graphics, effects, sounds, and sometimes even video clips or animated images. These elements are considered as discrete components of a slide and can be arranged freely. Powerpoint however enforces a certain style or rules to the arrangement of a slide, called a template. Once finished, the presentation can be saved and “presented” to an audience; this usually employs a video projector, or can also be streamed through the Internet.
