Worked Reasoning

Make each reasoning step visible: identify the knowns, choose the governing idea, apply it and check the result.

This extension applies that lens specifically to How Networks Work.

How Networks Work

A network connects devices so they can exchange data. Data is split into packets and forwarded across local links and routers to an addressed destination.

Core checkpoint: The internet is a network of networks, not a single cloud computer.

Grade 7 Computational Thinking and Privacy — Worked Reasoning: Which statement best captures the core checkpoint for How Networks Work?

The internet is a network of networks, not a single cloud computer.

Choose a solution before defining the evidence.

Ignore units, limits and boundary cases.

Assume the first result applies in every context.
