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

What is Contacts?

The iOS version of Address Book. Used to store details (phone numbers, email addresses and so on) of people you know. You can block a contact from calling you.

What is Control Centre?

New feature in iOS 7 (and continued in iOS 8 and iOS 9) that enables quick access to many frequently used settings and features, including the volume and brightness controls, the toggles to switch Airplane Mode, Do Not Disturb mode (which has its own entry below) and Bluetooth on and off, AirDrop, the camera and (on the iPhone) the torch. Accessed by sliding a finger up from the bottom of the screen.

Pleasingly, it is indeed spelled 'centre' rather than 'center', at least on iOS devices in this country. Control Centre is one of the features we discuss in our video '7 things we love about iOS 7'.

What is Crystalwell?

The name for a part of a superior subset of Haswell chips used in certain models of MacBook. 'Crystalwell' is literally the codename of the L4 cache (eDRAM) featured in the Iris Pro-enabled Haswell CPUs.

What is Dashboard? 

Feature in Mac OS X that displays icons for programs installed on the Mac OS X computer (similar in style to the Home Screen on iOS devices).

What is DFU mode? (What does DFU mode stand for?)

DFU stands for Device Firmware Update. It's a special mode you can put your iPhone in when you want to a) recover an ailing device, b) install an obsolete version of iOS, c) update your firmware or d) jailbreak. It differs from Recovery Mode in that Recovery Mode forciblt installs the latest version of iOS; DFU mode lets you keep things as they are.

What is DisplayPort?

A high performance digital interface used primarily to connect a laptop or computer to a display (monitor). It can include both audio and vidoe, and also supports other forms of data like USB. Most Macs use the same interface as Lightning to run Displayport.

What is the Dock?

Feature at bottom of iOS and Mac OS X home screen/desktop that contains icons for commonly used apps. On Mac OS X can also contain folders and documents and the Trash Can. 

What is Do Not Disturb mode?

Mode on iOS devices that blocks phone calls and makes the phone run on silent. Useful for meetings, public events and bedtime.
