Define raster graphics and vector graphics. Write any two differences between them.

Question

Accepted Answer

Raster graphics are digital images made up of tiny colored pixels, mostly used for photographs and detailed artwork. Vector graphics are images made using mathematical formulas, lines, shapes, and curves, mostly used for logos and icons. Differences: (i) Raster graphics become blurry when enlarged, while vector graphics stay sharp at any size. (ii) Raster graphics are pixel-based (e.g., JPG, PNG), while vector graphics are formula-based (e.g., SVG, PDF).
