Unit 1: Lesson 1 - Systems

What is a system?

• A group of unrelated components

• A group of interrelated components designed collectively to achieve a common goal

• A single component working independently

What is a process in a system?

• The results of the operation of any system

• Something put into a system

• A sequence of actions used to combine resources in order to produce an output

What is an example of a process in a system?

• Measuring ingredients, combining, and baking the mixture to make a cake

• The results of baking a cake

• The ingredients used in baking a cake

What is output in a system?

• The resources put into a system

• The sequence of actions used to combine resources

• The results of the operation of any system

What is a closed-loop system?

• A system that uses feedback to control the input and process of the system

• A system that operates without any feedback

• A system that requires human intervention

What often requires human intervention in a system?

• Open-loop systems

• Feedback systems

• Automated systems

What is the primary purpose of feedback in a system?

• To provide resources to the system

• To measure the output

• To regulate or control the processes or inputs

What are the "parameters" placed on the development of a product or system called?

• Optimization

• Requirements

• Trade-off

What does optimization involve in the context of product design?

• Making a product as functional as possible

• Choosing one quality over another

• Using manual controls

What is an example of a trade-off in product design?

• Making a product out of plastic instead of aluminum

• Making a product as functional as possible

• Using automatic controls
