-          There are two types of graphics used: bitmaps (paint graphics) and vectors (draw graphics).

-          Bitmaps graphics also called raster graphics. A bitmap represents the images as an array of dots called pixels. Bitmap graphics are resolution-dependent and generate large file sizes.

-          Vectors graphics are images drawn on the computer with software that uses geometrical formulas to represent images and only require a small amount of memory.


3. Video

-          Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion.

-          Photographic images that are played back at speeds of 15 to 30 frames a second and the provide the appearance of full motion.


The use of video:

-          The embedding of video in multimedia applications is a powerful way to convey information which can incorporate a personal element which other media lack.
