The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Create original awareness questions contrasting network devices with applications. Use a symptom case that deliberately lacks enough information for a single technical diagnosis, teaching the limits of the evidence.
02 / UNDERSTANDING
The concept in context
Domain-name resolution helps translate a human-readable name into addressing information used to reach a service. A successful lookup does not guarantee that the website itself is available, and a working local connection does not prove internet access. Separating layers helps identify which fact an awareness question actually asks without treating every connection problem as the same event.
03 / UNDERSTANDING
A worked learning case
Original educational case. In an original scenario, an office computer can print to a local network printer but cannot open an external website. Local communication works, so the symptom alone does not prove that every network component failed. Possible causes belong to other stages such as external connectivity, name resolution or the destination service; the case does not identify one without more evidence.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Original practice: Which role is most associated with forwarding traffic between networks: router or word processor?
Show the answer and reasoning
Router.
A router handles forwarding between networks, using network-layer addressing and routing information. A word processor is an application for editing documents and does not perform that role simply because it runs on a connected computer. The distinction is functional, so a definition should identify what a component does rather than rely only on its familiar name.
Two traps to watch for.
- Treating a browser and the internet as the same component.
- Assuming local connectivity proves an external service is reachable.
YOUR TOPIC-SPECIFIC LEARNING MAP
Learn from the attempt
Draw a local network and its router.
Label the browser as an application.
Explain name lookup separately from website response.
Explain the idea, apply it to a new situation, then check what changed in your reasoning.
