Raster OR Bitmap images are described by an array or map of bits within a rectangular grid of pixels or dots.
Vector images are described by lines, shapes, and other graphic image components stored in a format that incorporates geometric formulas for rendering the image elements.
When I had read this kind of definition, I was not able to digest what exactly it is?
But becomes very clear when we see example images. As of now I don't have images but would try to define in simple manner.
RASTER IMAGE: At 100% raster version of the image looks almost the same as the vector version. Notice that as soon as the raster version is scaled, the pixels on the edge begin to show and the edges no longer look smooth.

I am sure you will be able to identify the type of image I have used above :)
