GSM (Global System for Mobile Communications) is designed to replace the analogue mobile network (1G). For this reason, GSM is often called a 2G mobile network. It is improved by the addition of GPRS (General Packet Radio Services), and later EDGE (Enhanced Data rates for GSM Evolution) technologies.

TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G mobile network standard. It is also called UTRA/UMTS-TDD LCR. It is designed as an alternative W-CDMA standard in China by the Chinese Academy of Telecommunications Technology, Datang Telecom and Siemens. TD-SCDMA combines TDMA and CDMA.

UMTS is an abbreviation for Universal Mobile Telecommunications System. It is based on the GSM standard and belongs to 3G mobile networks. Developed by 3GPP and its biggest advantage is providing greater speed and spectral efficiency thanks to W-CDMA technology.

LTE (Long Term Evolution) is defined as a fourth generation (4G) technology. It is developed by 3GPP based on GSM/EDGE and UMTS/HSPA to increase the capacity and speed of wireless mobile networks. The subsequent technology development is called LTE Advanced.

A system on a chip (SoC) integrates various hardware components, such as a processor, graphics processor, memory, peripherals, interfaces, etc., as well as the software necessary for their operation.

Information about technological process, on which the chip is made. Nanometers measure half the distance between elements in the processor.

The primary function of a mobile device's processor (CPU) is to interpret and execute instructions contained in software applications.

The size (in bits) of a processor is determined by the size (in bits) of the registers, address buses, and data buses. 64-bit processors have higher performance compared to 32-bit processors, which in turn are more powerful than 16-bit processors.

Instructions are commands with which the software sets/controls the operation of the processor. Information about the instruction set (ISA) that the processor can execute.

Some processors have L0 (level 0) cache, which is faster to access than L1, L2, L3, etc. The advantage of having such memory is not only more high performance, but also reducing energy consumption.

Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and works much faster as system memory, and other levels of cache memory. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2.

L2 (level 2) cache is slower than L1, but in return it has a larger capacity that allows caching more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or in RAM memory.

The processor core performs program instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to be executed in parallel.

The clock speed of a processor describes its speed in terms of cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz).

Graphics processing unit (GPU) handles calculations for various 2D/3D graphic applications. IN mobile devices ah it is used most often by games, consumer interface, video applications, etc.

Like a CPU, a GPU is made up of several working parts called cores. They handle graphics calculations for various applications.

Running speed is the clock speed of the GPU, measured in megahertz (MHz) or gigahertz (GHz).

Random Access Memory (RAM) in use operating system and all installed applications. Data stored in RAM is lost after the device is turned off or restarted.

Information about the type of random access memory (RAM) used by the device.

Information about the number of RAM channels that are integrated into the SoC. More channels mean higher data rates.

The frequency of RAM determines its operating speed, more specifically, the speed of reading/writing data.

One of the main characteristics of the screen is the technology by which it is made and on which the quality of the information image directly depends.

For mobile devices, screen size is expressed by the length of its diagonal, measured in inches.

Approximate screen width

Approximate screen height

The ratio of the dimensions of the long side of the screen to its short side

Screen resolution shows the number of pixels vertically and horizontally on the screen. More a high resolution means sharper detail in the image.

Information about the number of pixels per centimeter or inch of the screen. Higher density allows information to be displayed on the screen with clearer detail.

Screen color depth reflects the total number of bits used for color components in one pixel. Information about the maximum number of colors that the screen can display.

Approximate percentage of screen area occupied by the screen on the front of the device.

Information about other screen features and characteristics.

Digital cameras use photo sensors to take photographs. The sensor, as well as optics, are one of the main factors in the quality of the camera in a mobile device.

Information about the dimensions of the photosensor used in the device. Typically cameras with larger sensors and lower pixel densities offer more high quality images despite the lower resolution.

The smaller pixel size of the photosensor allows more pixels per unit area, thereby increasing resolution. On the other side, smaller size pixel may have a negative impact on image quality when high levels photosensitivity (ISO).

The crop factor is the ratio between the dimensions of the full-frame sensor (36 x 24 mm, equivalent to a frame of standard 35 mm film) and the dimensions of the device's photosensor. The indicated number represents the ratio of the diagonals of the full-frame sensor (43.3 mm) and the photosensor specific device.

ISO indicators determine the level of light sensitivity of the photosensor. A lower value means weaker light sensitivity and vice versa - higher values ​​mean higher light sensitivity, i.e. better ability of the sensor to work in low light conditions.

Aperture (f-number) is the size of the aperture opening that controls the amount of light reaching the photosensor. A lower f-number means the aperture opening is larger.

Focal length is the distance in millimeters from the photosensor to the optical center of the lens. The equivalent focal length is also indicated, providing the same field of view with a full frame camera.

The most common types of flashes in mobile device cameras are LED and xenon flashes. LED flashes produce softer light and, unlike brighter xenon flashes, are also used for video shooting.
