3.- Name some disadvantages of using bitmap format graphics.

Bitmaps have two disadvantages. In terms of the amount of digital storage, bitmaps are memory intensive, and the higher the resolution, the larger the file size. The other disadvantage with bitmaps is when an image is enlarged, the individual coloured squares become visible and the illusion of a smooth image is lost to the viewer. This 'pixelation' makes the image look coarse.
