Smartphones and communicators

Smartphones and communicators

Smartphone (English smartphone - smart phone) - a mobile phone with extended functionality, comparable to a pocket personal computer (PDA). Also, the term "communicator" is often used to refer to some devices that combine the functionality of a mobile phone and a PDA.

Communicator (English Communicator, PDA Phone) is a pocket personal computer supplemented with the functionality of a mobile phone.

PDAs and communicators are full-fledged mini computers. Yes, unlike mobile phones and some smartphones, it has such components as RAM (in other words, memory for temporary storage of data during processing) a processor, in fact, this is one of the main advantages of PDAs and communicators, read-only memory (called a hard disk it is difficult, but it is present), some models are even equipped with video cards. Ordinary phones do not have all these devices, or rather, they do, but they are all too weak. Besides, the operating system (OS) is installed on the PDA and communicators, most often it is a Windows Mobile system, specially developed for PDAs and communicators, and is a mini copy of the original.
As a final fact, you can imagine this kind of programs as "ported games". "Ported games" are ordinary computer games that have been adapted for a PDA or a communicator, just adapted, and not written from scratch. On the example of the game Warcraft, you can see that all the functionality, graphics, capabilities, etc. are saved one to one. Also, PDAs and communicators support most of the computer formats, they have programs specially written for reading computer formats. The phone, on the other hand, will not be able to recognize some computer formats, even if there is some kind of program, because its "iron part" will not allow you to achieve this.

The touch screen of PDAs and communicators is vulnerable to all kinds of scratches and other defects. Yes, it is, the touchscreen is a very sensitive and fragile thing, and even contact with the keys can be fatal. But all problems have solutions, and the touchscreen is no exception. A special protective film is applied over the touchscreen, protecting it from scratches and damage. Plus, it makes the screen more rigid, making it easier to work with. The protective film is made of a special material and has a structure similar to a magnet on one of the sides, therefore it is glued to the screen without any auxiliary means such as glue. In addition, the film is designed for reusable cleaning in case of unsuccessful application. Upon contact with water, the adhesive part loses its ability to facilitate the washing process, but after 30-60 seconds after it has dried, the properties of the film are restored. Usually one film is enough for the whole life of a PDA or communicator. If you use the screen of a PDA or a communicator without a protective film, then most likely there will be scratches on it that will make it difficult to recognize the clicks or make the area around you generally not susceptible to any kind of clicks. Therefore, it is recommended to apply the protective film immediately after purchasing a touchscreen device.

When you press, you need to use only the stylus and in no case touch the screen with your fingers. Different devices are designed for different types of pressure, but when working with most of them, it is recommended to use a stylus. The stylus has a thin tip that allows you to hit even the thinnest points on the screen without worrying about pressure detection. The interface of devices intended to be tapped with a stylus most often contains small elements and a more concise look. Finger-taps, on the other hand, have larger controls and a more "bloated" look. This difference is only caused by the difficulty in pressing with a finger, since it is thicker than the stylus tip and requires more screen space for 100% recognition.

The communicator differs from a PDA only in the presence of telephone functions. Yes, that's right, a communicator is a PDA with phone functions. But besides this there is one more "but" PDA - an earlier type of devices and they are, as a rule, weaker than modern communicators, moreover, older versions of Windows Mobile are often installed on them. Nowadays, PDAs are practically not produced. But even a PDA can have the functions of a phone; by purchasing a special card that is inserted into the slot for a flash card, the integration of the functions of the phone is possible.

Using a PDA and communicators, you can remotely control devices. Quite right, some computer programs support this option, for example, you can control the music played on a PC using Bluetooth. Or control any device that is controlled via an IR signal (used in remotes), the TV is no exception. But all these functions require installation of additional software on your PDA or communicator. In rare cases, to a computer. In addition to control via Bluetooth and IrDA, there is a third method - direct connection with a cable, this method imposes some difficulties due to the fact that the cable limits the range of the PDA or communicator, but this method transmits information at a higher speed, which is sometimes important.

PDAs and communicators can be upgraded to a newer version of Windows Mobile. It is possible, but not all, the manufacturer most often supports the update, but unfortunately there is no such function in older models. Information about the possibility of updating is found in the instructions for use of the device. The update is carried out at the service center. But at his own peril and risk, the user of the device has the right to install a new system without the participation of the service center. But more often than not, this will lead to the loss of the warranty for the device. At the moment, the most recent is Windows Mobile 6.5. But there is already a statement about the seventh version of the OS. Versions differ from each other in interface and functionality, if 6.0 and 6.5 are improvements, then WM 2003 and WM6.0 are fundamentally different systems. There is a long time interval between them and no less list of fundamental changes. Therefore, it is recommended to purchase devices with the possibility of updating the OS in the future, this will provide a guarantee that you will not have to change your PDA or communicator just because of the release of a new OS.

In addition to a wide panorama of possibilities, we get an even wider and more varied panorama of glitches. On average, WM devices work quite stably and do not cause any complaints. But unlike simple phones where only two things can break: the phone and the battery, we really get a rather difficult task of troubleshooting. But if you follow the recommendations for handling PDAs and communicators, the likelihood that something will break itself is scanty. Nevertheless, the battery can make itself felt, just from old age it can remind of its age by rebooting the device or turning it off completely for a while, fast discharge and charging is also a sign of its malfunction. But in the new batteries there is also a fraction of the pleasant, nickel is a thing of the past and now there is no need to create a training ground for training new recruits, after purchasing it is enough just to charge it once and use it normally.

Some programs can instantly discharge the battery from 100% to 0. This is immediately said loudly, but some programs that run from the moment the device is turned on until it is turned off, for example, changing the interface can shorten the operating time after a full charge. There are even cases when some programs shorten the operating time from three days to 12 hours, so you should not install as much as possible just to have it installed. Remember that all these programs are also battery powered. The largest amount of energy is consumed by programs that change the interface, since they work all the time and often add the functions of an animated screensaver (background) and other gadgets, which dramatically drains the battery. In second place are plugins (add-ons that extend functions) for the Today screen, they also work from turning on and off, but unlike programs that change the interface, they have more modest functionality and fewer unnecessary things. Therefore, if your device has a reduced lifespan after recharging, do not rush to throw out the battery, review the list of installed programs and exclude unnecessary ones.

With the help of a PDA or a communicator, you can use icq or visit sites. Yes, this is so, WM has advanced capabilities in relation to the Internet, installation of popular modern browsers adapted for them is possible. Some devices can establish secure connections and use some of the personal computer protocols. Also, clients of the icq type have their own version adapted for WM and also have functionality similar to the original. Simply put, PDAs and communicators are not inferior to PCs in terms of the Internet and even surpass it, since they are portable and compact, they can use a wireless connection to the Internet.

The fall is 100% death for the PDA and the communicator. Indeed, this is almost certain death, but there is a chance of falling by an edge, while the maximum that threatens is a jolt impulse, and a cracked case as consequences, but if the parts are not fixed inside, it is unlikely that the device will ever work again. But if you fall screen down, the chance of death is really close to 100%. Therefore, it is advisable to buy a durable strap and wrap it around your hand, or just carry the device in a case, this will significantly soften the impact and reduce the chance of breakage, because restoring such a device is not a cheap thing, sometimes it is more profitable to just buy a new one.

Smartphones are smart but have limitations compared to WM devices. Partially yes. The platform of an ordinary phone is s40, and a smartphone is s60, from this it follows that a smartphone is just an improved phone, but nevertheless it has a kind of OS - Symbian OS which recognizes the * .sis format specific to it. Symbian OS allows smartphones to climb the ladder above simple phones, but this does not make them as functional and capable as WM devices. This is still a telephone system in which there are clear restrictions.

Smartphones usually do not have a memory processor and video card. As mentioned above, smartphones are only improved phones, so most often such concepts are not applicable to them, although in new models these devices knock out a line for themselves indicating the processor frequency. But even a powerful processor will not allow Symbian OS to achieve the same results that WM has achieved.

Smartphones are less fragile and more reliable than PCs or communicators. Since a smartphone is one step lower than WM devices, it most often lacks a touch screen, which reduces its fragility. As mentioned above for phones, a smartphone is only an improvement, or a phone or battery breaks down. In other words, due to the absence of a more powerful "base", the smartphone is less fragile and more reliable, but as a price for reliability - limited functionality.

Communicators will replace all other communication devices. At the moment, such a prospect is unlikely, since the cost of the communicator is at a rather high level for an ordinary consumer. Not everyone has a desire to deal with the OS, and not everyone wants to overpay for functions they don't need. Therefore, most likely, there will be something improved, more durable, but so far this option is a smartphone, although the phone is not inferior to the requirements of the average consumer. Therefore, at the moment it is difficult to say who will disappear and who will remain, but the fact that the communicator is the undisputed leader in technology does not cause any doubts. But the fact that phones with minimal functionality - "for communication" will always be in demand is also undeniable. The way out of this situation will be either the development of the general level of knowledge of a person, and as a result, even a grandmother can turn on music with one hand and sit in a comfortable rocking chair, enjoying her favorite performer. Or the categories "for communication" and "for games" will remain.
