29
SYSTEMS

• A SYSTEM IS ONE STEP ABOVE A MACHINE. IT IS A
  GROUP OF RELATED ELEMENTS THAT WORK TOGETHER FOR
  A SPECIFIC OUTCOME.

• QUESTIONS 1-2, AND 3-6 ARE ANSWERED USING THE
  SKILLS TEXTBOOK.

• Next step -
• a. Find and describe an example of a technology
  that goes beyond a basic machine, and provides an
  open loop system. Defend your choice.
• b. Find and describe an example of a technology
  that provides a closed loop system. You can find
  your own example (record the website you read it
  from) or you can choose this article online and
  describe the New York Times article, Dashboards
  That Promise to Do More Than Inform.
