Course outline
- How Devices Connect8 min · Lesson notes, example, action task · 2-question quizA network is a set of devices that can exchange information. Devices connect with cables or wireless signals, and they use shared rules, called protocols, so they understand each other.
- Routers, Switches and Wi-Fi10 min · Lesson notes, example, action task · 2-question quizRouters, switches and access points each do a different job. A router connects your network to the internet, a switch connects wired devices and an access point provides Wi-Fi.
- IP Addresses Explained10 min · Lesson notes, example, action task · 2-question quizAn IP address is a number that identifies a device on a network. It works a bit like a postal address, helping data find the right place.
- Diagnosing Connection Problems10 min · Lesson notes, example, action task · 2-question quizMost connection problems can be narrowed down with a few simple steps. Working out whether the problem affects one device, one room or everyone helps you know who to call.
- Secure Connections and VPNs10 min · Lesson notes, example, action task · 2-question quizConnecting securely protects your data on public and shared networks. A VPN creates an encrypted tunnel between your device and a trusted network, and good habits matter just as much.
