  1. 1. Systems<br />Eighth Grade Technology<br />Mr. Ruddle<br />
  2. 2. What is a system?<br />
  3. 3. A system is a group of interrelated parts that work together to accomplish a goal.<br />What does “interrelate” mean?<br />What is a system?<br />
  4. 4. When things interrelate, it means that they make connections with multiple things. <br />Usually, in a system, the interrelated parts depend on each other.<br />What does “interrelate” mean?<br />
  5. 5. Open-Loop Systems<br />Closed-Loop Systems<br />There are two types of systems<br />
  6. 6. Open-Loop Systems continuously interact with the environment or humans. Usually, an open-loop system does some function, then stops until it receives a command again.<br />Closed-Loop Systems operate and self-regulate without interaction with the humans except for initial input. Usually, a person enters an initial setting and the system completes the same operation until an new setting is entered.<br />What’s the difference?<br />
  7. 7. Open-Looped<br />Computer<br />Washing Machine<br />Dish Washer<br />Closed-Looped<br />Air Conditioner<br />Hot Water Heater<br />What are some examples?<br />
