Which statement describes the measurement of information as defined by the Shannon and Weaver model?
 
  a. The amount of information is measured by the amount of data in the message.
  b. The amount of information is measured by the number of meanings that can be assigned to a message.
  c. The amount of information is measured by the extent the message decreases entropy.
  d. The amount of information is measured by the number of characters used to create the message.

Question 2

Chaotic systems are in a constant state of change. This degree or scope of change that can occur has been described as the butterfly effect. The butterfly effect refers to:
 
  a. a minor change in input can create a major change in output, or a major change in input can result in minor changes in output.
  b. a major change in input will create a major change in output, and a minor change in input will create minor changes in output.
  c. a minor change in input can create a minor change in output; however, a major change in input will result in minor changes in output.
  d. a minor change in input may create a major change in output; however, a major change in input will create a major change in output.

Answer to Question 1

ANS: C
By decreasing entropy one decreases uncertainty. If a coin is thrown into the air, it may land on either of two possible sides, heads up or tails up. Once it lands, the other side of the coin can be determined. The options are coded zero (0) and one (1) and are the basis for building computer code.

Answer to Question 2

ANS: A
Chaotic systems are dynamic systems with reiterative feedback loops. A minor change in input can create a major change in output. This is often described as the butterfly effect. A butterfly's flapping wings in California can over time become a hurricane in New York.
