From this ordering, C will probably think that A showed B the sugar cube a second time as the last card, instead of the door. Removing a card causes C to conclude from the order of cards produced by B, an ordering of the photographs that is different from the original. Consider the photographs to be the samples of the original sound, and the cards to be the integer values that the digitizer can assign to a sample. Extending this analogy, an ordering of the photographs represents the original sound, the number of available cards represents the bit depth, and an ordering of the cards represents the digitized sound. Keep in mind that, although increasing bit depth increases the quality of the recorded sound, it also increases the file size.
More space is required to store each sample of digitized sound as the bit depth goes up.
