Someone at the dinner table mentioned "the cloud" last week. You nodded. You weren't entirely sure what it meant — but it seemed rude to ask.
You are not alone. These words get thrown around constantly, on the telly, in shops, even by your grandchildren — as though everyone simply knows. Most people don't. Here, finally, is plain English.
Here's what those six words actually mean — and what, if anything, you need to do about them.
Wi-Fi and the internet — aren't they the same thing?
People use these words as if they mean the same thing. They don't.
Think of it this way. The internet is like the national road network — millions of roads connecting everywhere to everywhere. Wi-Fi is the driveway from your house onto that road. You need both, but they're not the same thing.
Your internet connection comes into the house through a cable (from your provider — BT, Sky, Virgin, and so on). Wi-Fi then spreads that connection wirelessly around your home, so your phone and laptop don't need to be plugged in.
If the internet is slow, it's usually the road that's congested. If your phone can't connect at all, it's usually the driveway — your Wi-Fi — that's the problem.
The cloud — is it just... somewhere in the sky?
The cloud is not in the sky. It's in a building — specifically, a very large warehouse full of computers, usually somewhere like Slough or the outskirts of Dublin.
When your phone says it's backing up photos "to the cloud," it means it's quietly sending copies of those photos to that warehouse, over the internet, so they're safe even if you lose or break your phone.
The word "cloud" simply means "someone else's computer, somewhere else." That's it. Your photos, your emails, your documents — they live on those computers, and you access them via the internet whenever you need them.
So what? If you use iCloud, Google Photos, or OneDrive, your photos are already in the cloud — which is a good thing. They're backed up and safe.
Modem and router — what's the difference?
You almost certainly have one box in your home that does both jobs. Providers usually give you a combined unit these days — BT calls theirs the Smart Hub, Sky calls theirs the Sky Hub.
But inside that box, two things are happening. The modem talks to the outside world — it translates the signal coming in from the street into something your devices understand. The router then shares that signal around your home, to your phone, laptop, and telly.
When the broadband engineer installs your internet and hands you a single white box, they've given you both. You don't need to buy them separately.
Apps, programs, and websites — it's all the same, isn't it?
Nearly. The word app (short for application) usually means something you download onto your phone or tablet. Programs is an older word for the same idea on a computer — Microsoft Word, for example, is a program.
A website is different: it lives on the internet and you visit it through a browser. You don't download it; it's just... there, waiting.
The blurry bit: some things work as both. Amazon has a website you can visit, and an app you can download. Either way, you're buying the same thing. The app is often slightly faster and easier on a phone; the website is better on a computer with a bigger screen.
So what? If someone says "download the app," they mean: go to the App Store (iPhone) or Play Store (Android) and search for it. If they say "go to the website," open your browser and type the address.
The browser — and why you might have three of them
A browser is the programme you use to visit websites. It's the window through which you see the internet.
The most common ones are: Chrome (made by Google, the colourful circle icon), Safari (Apple's — the compass icon, on iPhones and iPads), Edge (Microsoft's — the blue wavy icon on Windows computers), and Firefox (the orange fox).
They all do the same job. You might have several installed because different programmes put them there over time. You only need one. Most people find Chrome or Safari perfectly good.
So what? Use whichever one you're used to. If a website ever says "please use a different browser," try opening it in Chrome — that usually sorts it.
Updates — why do they keep asking?
An update is a parcel of improvements sent to your device over the internet. Sometimes it fixes a fault. Sometimes it closes a security gap that criminals could otherwise exploit. Occasionally, it adds a new feature.
The reason your phone or computer keeps asking is that the company behind it (Apple, Google, Microsoft) found something that needed fixing, and they've fixed it — they just need to send it to you.
It is worth doing updates, even if the timing is inconvenient. A device that hasn't been updated in months is more vulnerable to fraud and viruses. When it asks, tap Tonight or Remind me later — just don't keep putting it off indefinitely.
In a nutshell
- Wi-Fi is how the internet reaches your devices at home — the internet itself comes from your provider.
- The cloud just means your files are stored safely on computers elsewhere, accessible any time you're online.
- Updates are important — do them, but never pay for one or hand over a password to a pop-up you weren't expecting.
What should I do?
- Find your browser — look for the Chrome, Safari, Edge, or Firefox icon on your phone or computer. That's where the internet lives.
- Check your cloud is on — on an iPhone, go to Settings → [your name] → iCloud. On Android, go to Settings → Google → Backup. If it's switched on, your photos are safe.
- Don't ignore updates — next time your device asks, tap Install Tonight and leave it plugged in. Job done.
- When in doubt, ask — these words are confusing because they were invented by engineers, not people. There are no silly questions.
The next time someone mentions "the cloud" at the dinner table, you'll know exactly what they mean. And if they get it wrong — well, now you can quietly correct them.
