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

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.

There are a variety of touchscreen technologies that have different methods of sensing touch, including resistive and capacitive.

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

Types of memory cards which can be used with this product.

The maximum size of memory card that can be used with this device.

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

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).

Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the interface used for connection, communication and power supply between computers and electronic devices. Every new version - for example 1.1, 2.0, 3.0 - is much faster than the previous one.

Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.

How headphones connect to a device e.g. wirelessly or via a cable and connector.

Multimedia Messaging Service (MMS) is a standard way to send messages that include multimedia content to and from a mobile phone over a cellular network

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

Device has a microphone and loudspeaker provided separately from those in the handset. This device allows multiple persons to participate in a conversation. The loudspeaker broadcasts the voice or voices of those on the other end of the telephone line, while the microphone captures all voices of those using the speakerphone.

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.

Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

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.

Frequency-modulated (FM) radio gives the clearest reception of any radio band. When used with a headset, it delivers stereo-like sound.

RDS (Radio Data System) means that information such as time, station identification and programme information can be displayed by the device.

The audio formats which this device or software can read/use e.g. MP3, MP4.

The type of video formats that can be used by this device.

Description of a technology platform including a processor, chipset, platform software and wired networking capabilities.

Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.

The type of battery in the device, e.g. nickel–cadmium (NiCd).

A measure of the charge stored by the battery. Determined by the mass of active material contained in the battery.

The device e.g. smartphone, tablet uses gravity to sense whether it should be displaying in portrait or landscape mode.

General Packet Radio Service is a wireless data transmission service based on packet transmission. For example, if an email is sent by GPRS it will be reduced into .packets. of information. Each individual packet travels to its destination by the quickest possible route. This means the different packets from the same mail can travel separately through foreign networks around the globe in order to avoid obstructions. At the pre-set destination they are rebuilt and presented to the recipient as a whole. GPRS offers instant access, and permanent connection between the mobile device and the network. With GPRS you only pay for information sent or received, rather than for connection time.
