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 turbo boost is an automatic, managed accelleration of the processor when one of the cores is overloaded.

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

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

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

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

Whether or not the rear camera features its own flash.

This is the maximum frame rate, also known as frame frequency and frames per second (FPS). It is the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to film and video cameras, computer graphics, and motion capture systems. Frame rate is most often expressed in frames per second (FPS) and is also expressed in progressive scan monitors as hertz (Hz).

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

Device focusing a camera or other piece of equipment automatically.

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

System used to play music or speech.

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.

Depending on the make of the device, a different application is pre-installed that can understand voice commands and complete tasks for a user, e.g. Apple Siri, Amazon Alexa.

The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A+++ to G on the label, A+++ being the most energy efficient, G the least efficient.

The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
