The Internet & Its Uses
Three interactive trainers take you through the internet side of the course — how the web actually reaches you, the money that exists only online, and how to stay safe from the threats that target it. The first folds sub-topics 5.1–5.3 into one trainer; the others cover digital currency and blockchain, then cyber security. Each one teaches the idea, lets you drill it, then tests you — work through them in order or jump to the skill you need.
5.4
Digital Currency & Blockchain Lab
Digital currency and cryptocurrency, centralised vs decentralised systems, and how blockchain’s time-stamped, linked digital ledger makes transactions tamper-evident.
5.5
Cyber Security Lab
The 8 threats and 9 solutions, which defence defeats which threat, the phishing-vs-pharming trap, and what actually makes a password strong.
