What's inside
48 chapters, in the order that makes it stick
The two-step method, throughout
Fifty questions, answered
A full glossary
How to read a spec sheet
The chapter that prevents real loss
Sound familiar?
Two cables that look identical
One charges your laptop, one does not, and one carries a picture to a screen. There is no way to tell them apart by looking, and nobody ever explained why.
Standing in the shop with two boxes
The numbers on both look reassuring and neither means anything to you, so you buy the dearer one because at least that feels safe.
The advice assumes you already know
You search for the problem and the answer is written in the vocabulary the problem is described in. So you nod and move on.
„The shape of the connector tells you what it fits. It tells you almost nothing about what it can do."
Eight parts, one machine
I · The machine itself
Processor, memory, storage, graphics, the board they sit on, and the two physical limits nothing escapes.
II · Plugs, ports and cables
USB, Thunderbolt, HDMI, DisplayPort, Ethernet and charging — where most people lose the most time and money.
III · The screen
Resolution, panel types, refresh rate, colour, and why text sometimes looks slightly wrong.
IV · The operating system
What it actually does all day, and what really separates Windows, macOS and Linux.
V · Files and formats
Why the same photo can be four sizes, what lossy really costs, and the backup rule that saves you.
VI · Networks and the internet
What happens between typing an address and seeing a page, and every box involved.
VII · Staying safe
What actually threatens ordinary people, in order of how likely it is to happen to you.
VIII · Buying, keeping, replacing
Reading a spec sheet, what to upgrade first, and when nothing is wrong at all.
This is for you if …
You use computers well and never learned how they work
You are productive and you have been nodding along for years. This closes that gap without starting from 'this is a mouse'.
You are about to spend money
A laptop, a monitor, an upgrade. Knowing which specification actually limits you is worth more than any review.
You are the person everyone asks
Family, friends, the office. This gives you the explanations that make it click for them, and the ones that stop being wrong next year.

Common questions
Do I need any technical background?
No. Every term is explained the first time it appears, and every idea is given twice — once in the correct words and once in plain ones. Part I builds the foundation the rest of the book leans on.
Isn't this all on the internet for free?
Most of it is, scattered across thousands of pages written for people who already know the vocabulary. What is not free is having it in one order, explained consistently, so that each part builds on the last instead of assuming it.
Will it go out of date?
The specific parts will — version numbers and current generations always do. The trade-offs will not, because they are physical: higher frequencies carry more and reach less, heat limits sustained performance, distance costs time. The book is written around those rather than around this year's models.
Does it recommend what to buy?
Deliberately not. Models change every year and a book cannot chase them. What does not change is how to read a specification, so that is what you get instead — including the phrases that are hiding something.
Is it Windows, Mac or Linux?
All three. Part IV covers each honestly, including what each does badly, and the rest of the book is about hardware, files, networks and security, which are the same whichever system you use.
