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.

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 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.

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

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).

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

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).

The type of USB connector/port that this product has.

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

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.

The shape or design of the product.
