Blown to Bits Chapter 3 and 5
define meta-data and give an example - correct answer ✔-a set of
data/information about other data
ex. name of a document or the last modification data of a document


define steganography - correct answer ✔the hiding of information within
other information


what are filename extensions and what are they used for? - correct answer
✔-they are the last 3 letters of a document
-they are used to indicate how the contents are to be interpreted
ex. .doc .pdf .jpg


define spatial coherence and how it allows us to transmit images using fewer
bits - correct answer ✔-it is the notion that the color does not change from
pixel to pixel in most images
-used in lossless representations
-recognizes that there is no need to repeat a specific color value over and
over because nearly all pixels in the block will have the same color


define temporal coherence and how it allows us to transmit images using
fewer bits - correct answer ✔-it is the notion that images are unlikely to
change in color frame to frame
-recognizes that large parts of a picture generally do not have to be
retransmitted to the home after the frame changes in a short amount of time (it
can remain the same and only significant changes should change color)
