Answer Key
Years 5–6 Digital Systems · Modules 41–52 · Student wording will vary for definitions
1strong password — A password that is long and hard for others to guess. It avoids names, birthdays and common words like password123, and it mixes letters, numbers and symbols.
2passphrase — A password made of several unrelated words that is long but easy to remember. You can add numbers or symbols to make it stronger.
3password re-use — Using one password on many accounts. If a data breach leaks it, attackers try it on other sites and can unlock every account that shares it.
4unique passphrase — A different passphrase for every account, so if one is leaked in a breach, criminals cannot use it to get into your other accounts. Change it straight away after a breach.
5password manager — A tool that stores and fills in many passwords for you, kept safe behind one strong master passphrase that only you know.
6multi-factor authentication — A login step that asks for a second proof of identity, like a phone code or app prompt, as well as your password. A stolen password alone is not enough.
7phishing — A fake message that tricks you into giving away login details or personal data. Do not click its links; tell a trusted adult.
8log out — Ending your session on an account so the next person using a shared device, like a school or library computer, cannot open or use your account.
9public Wi-Fi risk — Data sent over public Wi-Fi can be seen by others, so avoid logging in or paying there. Use mobile data instead for sensitive tasks.
10software update — A new version of a program that fixes security weaknesses so attackers cannot use them to reach your data. It covers operating system updates, app updates and automatic updates.
11secure access — Using a unique passphrase for each account, plus safe habits like logging out on shared devices and keeping software updated, to protect all your systems and accounts.
12system description — A full description of a digital system: it names the hardware components and software, shows the link to a network, and explains what each part does.
