Size of the display for this product, measured diagonally, usually in inches.

Resolution of the display for the system

The technology used in the display e.g. plasma, LED.

Brightness is quality of the amount of radiating light emitted from the screen. The brightness rating is measured in candelas per square meter, commonly known as 'nits'.

This means that LEDs can be controlled individually (or in clusters) to control the level of light/color intensity in a given part of the screen.

The manufacturer that produced the processor.

A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.

The model number for the processor in a computer.

The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.

The amount e.g of data which can be stored inside the device.

The device includes a card reader e.g. a card reader in the disk bay of a computer or thin client to permit log-on using smart/pin cards.

Used for the storage of data e.g. HDD (hard disk drive), SSD (solid-state drive).

Indicates the type of the camera at the back of the product, dual or single.

The resolution of the images produced with the rear camera, given in MP (megapixel. 1 MP = 1 million pixels).

Indicates the digital zoom capacity, the number of times that the picture is enlarged thanks to digital technology.

Indicates the optical zoom capacity, which is the number of times that the picture can be enlarged with the optics of the camera.

Device focusing a camera or other piece of equipment automatically.

Whether or not the rear camera features its own flash.

This camera function compensates for slight shaking movements caused by an unstable position and ensures smooth footage even in suboptimal conditions.

Recording moving visual images.

Camera at the front of the product.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

The type of bluetooth technology in the product e.g. Bluetooth Smart (v4.0).

Connection of this device is done via Wi-Fi in a high standard.

The type of wireless local area network (LAN): ad-hoc (where units in a network communicate peer-to-peer) or Infrastructure (units communicate with each other via an access point). A LAN interconnects computers in a small area e.g. home, school or office.

AirPlay (previously called AirTunes when it was for audio only) is a proprietary protocol stack/suite developed by Apple Inc. that allows wireless streaming of audio, video, and photos, together with related metadata between devices. Originally only implemented in Apple's software and devices, Apple has licensed the AirPlay protocol stack as a third-party software component technology to manufacturer partners for them to use in their products in order to be compatible with Apple's iDevices.

Based on the PCI Express and DisplayPort technologies, Thunderbolt technology supports both data devices and displays.

A docking connector is a connector used to attach a mobile electronic device simultaneously to multiple external resources e.g. Apple Lightning, Micro-USB.

Type or category of the device.

What the casing of the product is made of.

The format is determined by shape, size, presentation and medium.

The colour e.g. red, blue, green, black, white.

SAR stands for Specific Absorption Rate which is the unit of measurement for the amount of radio frequency (RF) energy absorbed by the body when using mobile equipment.

Assisted GPS, generally abbreviated as A-GPS, enhances the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.

Electronic instrument used for navigation that shows directions in a frame of reference (north, south, east, west) that is stationary relative to the surface of the earth.

Whether the navigation system can locate the phone's position.

The computer, smartphone etc. can only be used when the correct password is entered, therefore making it more secure.
