Apple user's dictionary of tech jargon

David Price | May 10, 2016
From Arrangement Mode to Xcode: we explain all the jargon in our plain-English dictionary of tech terms, focusing on concepts that affect Apple fans

While 4G will eventually replace 3G, for now both networks run side by side, and your average iPhone can access both 3G and 4G (as well as lesser known standards such as Edge). Most mobile phone providers are now offering 4G along with 3G as standard, for either the same price or a slight increase.

Carphone Warehouse (which admittedly has a vested interest in bigging up the technology) says 4G coverage is accessible to 80 percent of the UK population at present, and claims this number will rise to 98 per cent in the next year.

What is 4K?

A new type of television and monitor that is hoping to replace high-definition. 4K stands for 4,000, and is so named because it will have around 4,000 horizontal pixels. This compares to the 2,560 x 1,440 found on a current 27-inch iMac. Although actual resolutions still vary, the most common is 3840x2160 pixels, which is four times larger than a high definition television set.

Editing 4K video is very demanding on a computer, and the Mac Pro is designed to be capable of 4K video editing.

(Incidentally, one of the rumours about the iPad Pro suggests that it will have a 4K screen, which would be very impressive indeed.)

What is an accelerometer?

This is a motion detector sensor that Apple first introduced in the iPhone. It is now found in the iPhone, iPod touch and iPad. It is the sensor that detects which way up you are holding the device, so the screen can rotate accordingly. Some games (and other apps) use the accelerometer as an input control (twisting the iPhone to recreate the movement of a steering wheel, for example)

What is accessibility?

Accessibility (in a technology context) is a general term for features offered by devices and operating systems to make them easier to use for people with visual or physical impairments.

What is Address Book?

Mac OS X program used for storing the names and addresses of people you know. The equivalent program is called Contacts on iOS devices.

What is Airplane Mode?

A simple feature of iOS that switches off all cellular, wireless and Bluetooth activity on an iPhone or iPad. You won't be able to pick up emails or tweets, access Game Center or (obviously) browse the internet. Can be switched on via the Settings app or, in iOS 7 or iOS 8, from the Control Centre.

It's designed to make smartphones and tablets safe for use on a plane, but in our experience you'll probably still be asked to switch off the device completely for take-off and landing.
