Crop factor is the ratio of the dimensions of a full frame camera's sensor (36 x 24 mm, which equals the frame size of a 35 mm film) and the dimensions of the image sensor of the device. The number shown is the ratio between the diagonals of a full frame sensor (43.3 mm) and the sensor in question. Information about the manufacturer and model of the image sensor used by this camera of the device. One of the main characteristics of the display is its type/technology, on which depends its performance. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology

Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width Information about the dimensions of the image sensor used in the device. Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.

Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.

Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well.

Network Band: The bandwidths supported by the device may vary depending on the region or service provider. UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

Stay in touch when your phone is out of reach. Galaxy Tab Active Pro seamlessly synchronises to your Galaxy smartphone, so you can take calls when they come in just like you answer your phone. It also allows you to reply to text messages, so you’re never out of the loop. Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.

A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC Memory size - User memory is less than the total memory due to storage of the operating system and software used to operate the tablet features. Information about additional software and hardware features of the front camera which improve its overall performance. This is a graded product. A1 products are "as new" but have been box opened.
