WIth bitmapped images they are stored through the pixels they are made up of which takes up a lot of memory but with vector graphics the image is only stored through the attributes it consists of. Due to vector graphics having to store less than bitmapped the file size tends to be smaller but can change depending on the image itself. bitmapped is the type of image that is tended to be used with most images as it gives a more vivid and clear picture and vector graphics are used for things like logos. Vector graphics have advantages over bitmapped such as they can be re-sized, smaller file size and if it is sent to another location the resolution of the image is able to change if the location has a higher resolution. The advantages to bitmapped is that you have the ability to edit your images to pixel level, so you can make changes in detail and the file size of the image is fixed.
