Match a Component to Its Responsibility

Supplied materials

• Paper and pencil; answers may also be spoken or typed.
• All cases, labels, numbers and rules are supplied on this page. No real account, private information or purchase is needed.

Learn the idea

A computing system has parts with different jobs. A processor carries out program instructions, working memory holds information in current use, saved storage keeps files, and a network connection exchanges data with another system. Real components cooperate; the paper model isolates their main responsibilities.

Match the stated responsibility to the component that provides it in the model. Saved storage and working memory are not interchangeable roles.

Use this supplied case: Carries out the program’s current calculation. Which component matches the responsibility? Use the details in this example. Say which detail helped you choose. This pretend example does not tell us how every real system works.

1. Follow the worked example one step at a time. Say or draw what happens.
2. Match the stated responsibility to the component that provides it in the model.
3. Say which detail makes the example answer fit. Pick another answer and say why it does not fit.
4. Try the question and practice questions. Read the rule again if your answer does not match the explanation.

Take it further

A program needs instructions executed, current values held, and a finished file kept. Expected: processor, working memory, and saved storage have those distinct primary roles.
