Learn the idea

A local network connects nearby devices under a common arrangement. The Internet connects many networks. A local printer may work even when Internet access is unavailable. The supplied map states which connections exist; use those lines rather than assuming every device reaches every service.

Choose the destination reachable through the connections explicitly drawn in the model. A missing Internet connection does not mean every local connection has failed.

Use this supplied case: Tablet wants to send a stored drawing to the local printer. Map: tablet connects to local printer; its Internet line is broken. What is supported? Use the details in this example. An adult may read the words aloud. Point, draw or say your answer.

1. Follow the worked example one step at a time. Say or draw what happens.
2. Choose the destination reachable through the connections explicitly drawn 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

New map: X links to local device Y; no line reaches remote service Z. Expected: X can use the drawn path to Y, while this map supplies no route to Z. Name the actual connection that supports each decision.
