Information about the width, i. Information about the height, i. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. GSM Global System for Mobile Communications was developed to replace the analog cellular network 1G , therefore it is referred to as a 2G mobile network.
Based on the GSM standard, it is deemed as a 3G mobile network standard. There are several network technologies that enhance the performance of mobile networks mainly by increased data bandwidth. Information about the communication technologies supported by the device and their respective uplink and downlink bandwidth. 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. Its main function is to interpret and execute instructions contained in software applications.
The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. Information about the set of instructions the processor can execute. The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. The L1 level 1 cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory.
In some processors the search in L1 and L2 is simultaneous. The L2 level 2 cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory RAM. 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. The frequency of the processor describes its clock rate in cycles per second.
They handle the computation of graphics in various applications. Data in the RAM is lost after the device is turned off or restarted. More channels mean higher data transfer rates. Information about the capacity of the built-in storage of the device. Sometimes one and the same model may is offered in variants with different internal storage capacity.
The various types of memory cards are characterized by different sizes and capacity. Information about the supported types of memory cards. 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.
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. The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display.
Sensors vary in type and purpose. They increase the overall functionality of the device, in which they are integrated. Digital cameras use image sensors for taking photos.
The sensor characteristics are some of the main factors determining the quality of the camera integrated in the mobile device. Cameras of mobile devices use mainly a LED or a Xenon flash. The LED flash has a softer burst of light and in contrast to the much brighter Xenon flash, is used for recording videos as well.
One of the main characteristics of the cameras of mobile devices is their resolution, which shows the number of pixels on the horizontal and vertical dimensions of the image. Information about the maximum number of frames per second fps , supported by the device while recording a video at maximum resolution.
Some of the main standard frame rates for recording and playing video are 24p, 25p, 30p, 60p. Information about additional software and hardware features of the privamery camera, which improve its overall performance. The loudspeaker is a device, which reproduces various sounds such as ring tones, alarms, music, voice calls, etc.
Information about the type of speakers the device uses. Some devices have the possibility to serve as Wi-Fi Hotspots by providing internet access for other nearby devices.
The technology has several versions, which improve the connection speed, range, connectivity and discoverability of the devices. Information about the Bluetooth version of the device. Bluetooth uses various profiles and protocols related to faster exchange of data, energy saving, better device discoverability, etc.
Some of those supported by the device are listed here. There are several USB connector types: Type of the USB connector used by the device. With each following version the rate of data transfer is increased.
Information about some of the most widely used connectivity technologies supported by the device. List of some of the most common audio file formats and codecs supported standardly by the device. List of some of the most common video file formats and codecs supported standardly by the device. The capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours. The battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion Li-Ion and the lithium-ion polymer battery Li-Polymer.
Brand Brand name of the company that manufactures the device. Samsung Model Model name of the device. Black White Body materials Materials used in the fabrication of the device's body. Dual SIM stand-by Both cards are active. Samsung Galaxy Tab Q.
Samsung Galaxy Star 2 Plus. Samsung Galaxy Ace 4. Samsung Galaxy J1 Ace. Samsung Galaxy Express 3. Samsung Galaxy J3 Lava Iris X1 Atom. Width Information about the width, i. Height Information about the height, i. Volume Estimated volume of the device, calculated from the dimensions provided by the manufacturer.
Features Information about some specific features related to the SIM card s of the device. When one is busy, the other is not active. Mobile network technologies There are several network technologies that enhance the performance of mobile networks mainly by increased data bandwidth. Operating system OS Information about the operating system used by the device as well as its version. Process technology Information about the process technology used in manufacturing the chip.
Level 1 cache memory L1 The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. Level 2 cache memory L2 The L2 level 2 cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data.
CPU frequency The frequency of the processor describes its clock rate in cycles per second. Storage Information about the capacity of the built-in storage of the device. Types The various types of memory cards are characterized by different sizes and capacity. Diagonal size In mobile devices display size is represented by the length of its diagonal measured in inches.
