no loss of quality when resized
requires fast computer
consumes less storage space
difficult to recreate complex real-life scenes
data stored grids of pixels
zooming reduces quality
increasing size reduces quality
lower processor requirements
high memory requirements
consume lots of storage space
photographs
Bitmap
