The optical format of an image sensor is an indication of its shape and size. It is usually expressed in inches. GPRS, EDGE, CDMA2000 EV-DO Rev 0, CDMA2000 EV-DO Rev A, UMTS, HSDPA, HSUPA, HSPA+, TD-LTE, LTE, LTE-A, SA/NSA, Sub6

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. The L3 (level 3) cache memory is slower than L2, but has a larger capacity, instead, which allows it to cache more data. Just like L2, it is much faster than the system memory (RAM). Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSMOne of the main characteristics of the display is its type/technology, on which depends its performance. 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. 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

Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technologyA 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.
