Bitmap.
Bitmap (raster) images are a large number a small squares based in a grid known as pixel. The pixels have a specific location which also has a colour value to each one are assigned to.
Bitmap can represent gradation of colour and shade. The disadvantage of bitmap is, they only represent a fixed number of pixels in a grid so they appear jagged and lose detail if they are resized or displayed at a higher resolution.
Bitmap are mostly used for artwork created in painting programs and continuous-tone images e.g. photos
