Phones prestigio multiphone 5450 duo. The main camera of a mobile device is usually located on the back of the body and is used for taking photos and videos

General characteristics

Type

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

Almost all modern smartphones have Wi-Fi and USB interfaces. Bluetooth and IRDA are a little less common. Wi-Fi is used to connect to the Internet. USB is used to connect your phone to a computer. Bluetooth is also found in many phones. It is used to connect wireless headphones, to connect your phone to wireless speakers, and also to transfer files. A smartphone equipped with an IRDA interface can be used as a universal remote control. Glossary of terms for the category Mobile phones

Wi-Fi, Bluetooth, USB Satellite navigation

Built-in GPS and GLONASS modules allow you to determine the phone's coordinates using signals from satellites. In the absence of GPS, a modern smartphone can determine its own location using signals from cellular operator base stations. However, finding coordinates using satellite signals is usually much more accurate. Glossary of terms for the category Mobile phones

Processor size

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.

ARMv7
Level 1 cache (L1)

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 than both system memory and other cache levels. 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.

32 kB + 32 kB (kilobytes)
Level 2 cache (L2)

L2 (level 2) cache is slower than L1 cache, but in return it has a higher capacity, allowing it to cache 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.

Touch screen: There are two types of touch displays: resistive and capacitive.
Resistive displays consist of two transparent plates that make electrical contact with each other at the point of pressure. Such displays react to mechanical force using any object. Devices equipped with such displays are equipped with special wands - styluses, which are convenient to operate the device.

The disadvantage of such a display is that the screen is highly susceptible to scratches and abrasions; when operating with your fingers, you need to make an effort for the device to react.

The second type of touch screens - capacitive ones, are free from these disadvantages, because... were originally developed for direct finger control, without the use of any third-party objects or tools.

At each corner of the display there are electrodes that apply the same alternating voltage to the conductive layer of the display. When touched by a finger or other object capable of conducting current and having its own electrical capacitance, current leakage occurs. The closer the touch point is to the electrode, the lower the electrical resistance of the display will be and, accordingly, the current strength will be greater.

Devices with such displays respond exclusively to hand control; touching the surface of other objects, due to the absence of their own electrical capacitance, will not lead to the closure of the contact point-electrode circuit and will not have any effect on the device. If customizable, such a display can be configured not even to touch with a finger, but only to bring it to the surface.

An undeniable advantage of such displays is their very high resistance to mechanical damage, due to the possibility of using fairly thick and durable surface glasses.

Another advantage is the very high accuracy of determining touch coordinates, down to one pixel. When controlling the hand, of course, such precision is unclaimed, but when using special conductive styluses it opens up great potential opportunities.

Capacitive displays are more transparent (about 90%) than resistive displays, whose transparency does not exceed 85%, which makes it possible to display a higher-quality image on their surface.

The physical resource of capacitive displays is at least 200 million clicks, which approximately corresponds to 6.5 years of clicks with an interval of 1 second. Surface contamination with non-conductive substances does not affect their operation.

The relative disadvantages of capacitive touch displays are the need to use large displays in mobile devices, due to the need to ensure comfortable hand control, and their higher cost compared to resistive ones.
