Networks

What is it

A network is two or more computers connected together to share data and resources — ranging from a small home Wi-Fi network to the entire internet.

Why it matters

Nearly everything you do on a device today involves a network in some way. Understanding how data actually travels between devices demystifies the internet instead of treating it as a black box.

Exam tip

Know the difference between LAN (Local Area Network) and WAN (Wide Area Network) with a concrete example of each — this distinction is one of the most reliably tested facts in the networks topic.
