Do you want the textbook answer or the easy answer?? lol
Raster layers "are layers with data composed of individual elements, called pixels, arranged in a grid." These would be the layers created when you add papers and elements. Vector layers "are layers with only vector objects (lines and shapes), vector text, or vector groups....which are composed of geometric characteristics and their locations." PSP will automatically add a vector layer when you use the text tool or the preset shapes tool.

For the most part, I use raster layers. Vector layers will be created when you use the text tool, pen tool, or preset shapes in PSP.
