Technology

How our gadgets, computers, code and the internet really work - from your first tap on a screen to programming, AI and cybersecurity, one tiny step at a time.

Technology covers computers and the internet from the ground up: hardware, how the internet works, files and data, algorithms, programming concepts, security and privacy, plus the social questions technology raises.

The digital safety and privacy units are the most immediately useful on the whole site. Understanding passwords, phishing and what services actually do with data changes behaviour in a way that few other topics do.

Almost everything now runs on systems most people treat as magic, and that gap is exploited routinely - by scams, by interface design, and by companies whose interests are not yours. This track closes some of it.

Units: 18
Steps: 415
Questions: 2,148

Who this track is for

Primary digital literacy through to secondary computing and introductory computer science.

How to approach it

Do the safety and privacy units first, they pay off immediately
Algorithms are easier if you write the steps out in plain language first
Understanding how the internet works demystifies most of the rest

Study guide · 8 min readHow to Learn TechnologyKnowing where the buttons are is not knowing technology, and it expires with every redesign. A guide to the structural knowledge that does not, why you should learn networks before apps, and how to think about AI without either hype or panic.

What you will be able to do

Explain what happens between typing a web address and seeing a page
Say why a long password beats a complicated short one
Describe what a machine learning model is actually doing
Tell the internet from the web and say why the distinction matters

The thing people get wrong

That being good with technology means knowing where the buttons are. The useful knowledge is structural - what a network is, what a file is, what a program does - and it survives every interface redesign.

If you only do 3 units

What a computer is, how computers talk to each other, and how not to be the weak point. Those three cover most of what an ordinary person actually needs.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
