Practice Network in CS Thinking

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A group of interconnected computing devices that can communicate and share resources with each other. Networks range from small local area networks (LANs) connecting devices in one building to wide area networks (WANs) spanning cities or countries, up to the global internet.

A network is like a postal system for computers โ€” it connects them so they can send and receive information.
