1. System A collection of parts that perform a function

2. Input: items needed to start the system What are some inputs into a car?

3. Explain the process in a car Process: the mind of the system, which considers the inputs and decides what to do

4. What is the output on a car? Output: the system's response to being activated

5. Open-loop systems - set up to get a result, but there's no feedback to check the results - these create waste for which there is no use For example, bathroom heater The aim of the system would be to heat a bathroom. When turned on, the heating would stay on until it was turned off, regardless of whether the bathroom remained cold or became too hot.

6. Closed-loop systems Are able to correct in order to meet target results. Have a Feedback : a sensor is used to look at the output and adjust the process For example: modern whole house heating/AC systems a thermostat could be added to measure the temperature of a room and compare it to a set target. If the room became too cold, the thermostat would turn the heating on and if the temperature became too hot the system would be turned off.

7. Is this open or closed loop? Why?

9. Is cruise control an open or closed loop system? Why?

10. Is a basic light switch open or closed loop system? why?

11. Is a light that shuts off if no one is in the room, open or closed loop? Why?
