What is raster graphics used for in 2d games, and what is vector graphics for?

To render everything you see on the screen. Locations, characters, special effects, that's it.
There are games built entirely on a raster, and there are games entirely vector.

And why?

Because if you do not use any, then the game will not be graphic. (there are such ones)
Programs for creating graphics are easily googled. You can even start with paintbrush.
If it seems to you that the answer is in the style of KO, then thanks, I tried.
Try to describe in a little more detail what exactly you are interested in.
