Flash vs. raster images

I need to know the difference in how these two draw things. Here are some stuff in what I M thinking.
Raster

-think of it like a graph where each pixel is told what color to be (by rgb or hex???)

Flash (vector)

-Draws stuff by saying what to draw. Can you give me an example of how a circle and rectangle would be drawen in flash? WOuld it be like:

Circle

-center (123,40)
-radius 32
-border 5
-color (123,42,85)
-bordercolor (52,71,191)
-bordertype solid
-would they not have radius and have diameter or something like that?

Rectangle

-4points (45,72)(69,72)(45,12)(69,12)
-border 5
-color (123,42,85)
-bordercolor (52,71,191)
-bordertype solid
