- Account
- Your personal identity with a company, a name and password that prove the things inside belong to you. It lives on the company's computers, not on your device, which is why you can reach it from any phone or laptop.
- App
- A single tool for a single job, the camera, the weather, the bank, sitting on your device. Each app is its own room; you're always in exactly one at a time.
- Backup
- A safe copy of your things, photos, contacts, files, kept somewhere other than your device (usually in an account, "in the cloud"), so that losing or breaking the device doesn't lose the things.
- Browser
- The app you use to look at websites, the one where you type an address and reach the internet.
- The cloud
- Not a real cloud, just other people's distant computers where your backed-up things are safely stored and reached over the internet. "In the cloud" means "kept safely elsewhere, not only on your device."
- Factory reset
- Erasing a device completely, back to its blank, like-new state. The essential step before giving away, selling, or recycling any device, so your private information doesn't go with it.
- Icon
- A little picture that stands for an app or an action. Learn what its job is, not one exact design, since designers redraw them constantly.
- Operating system
- The invisible software the whole device runs on, the world the apps live in. Different brands of phone run different ones underneath.
- Password manager
- A locked, trustworthy tool that remembers all your passwords so you only have to remember one. What most people who are "good with passwords" quietly use.
- Screenshot
- A photo of your own screen, taken by the device, so you can save or show exactly what you were looking at, a confirmation number, a confusing message.
- Update
- A newer version of an app or the device's software, often fixing security holes, so installing updates is one of your quiet protections, not just a nuisance.
