Slides in a PowerPoint presentation are akin to a blank paper — you add your content to the slides in much the same way as you use your imagination to populate a piece of paper. However unlike a blank piece of paper, PowerPoint categorizes each slide type into one of its prescribed layouts — examples of such layouts include the Title layout, the Title and Content layout, the Title Only layout, the Blank layout, and several more layouts.
