Bitmap and Vector Graphics

Vector graphics are computer graphics images that are defined in terms of points on a Cartesian plane which are connected by lines and curves to form polygons and other shapes. Vector graphics have the unique advantage over rasater/bitmap graphics in that the points, lines, and curves may be scaled up or down to any resolution with no aliasing

Raster graphics or Bitmap image is a dot matrix data structure that represents a generally rectangular grid of pixels (points of color), viewable via a monitor, paper, or other display medium. Raster images are stored in image files with varying formats.
