Why the mobile phone is important for people. What is a smartphone for and how it differs from a mobile phone. The speed of the program
It seems to me that a modern telephone is not only a way of communicating with outside world but also the center of entertainment, because it is always with you. On the road, at work, on vacation, you can always listen to music, play, go online, chat in ICQ and, of course, make calls. So why do you need a phone - just to call or is it something more than just calls and text messages?

you can add more "show off"
I personally don't understand why the phone needs an mp3 player. "Listen to music," - the answer suggests itself. Well, I have never watched my classmates and acquaintances in general, so that they walk with headphones, honestly. The first time, after the purchase, maybe ... Yes, and the quality of the majority is questionable and the phone is quickly discharged. Itself would have bought from mp3 but only for best quality ringtones.
The main thing is that the phone rings, is convenient and cute.
The phone was originally made in order to make calls, and then they began to attach games, the Internet, a camera, a video camera, a player and other "amenities" to it ... In my opinion, games in the phone are not needed at all (IMHO), in mine they were - deleted (they only take up space), I hold the same opinion regarding everything else, I think that this is just the desire of manufacturers to increase the cost, because when one thing combines many functions that are not peculiar to it, these functions, as a rule, do not work very well ...
I completely agree with this.

Apparently you didn't have to travel long.
When you play your favorite songs in your headphones, time flies faster. I’m already silent that some phones allow you to watch movies.
I always listen to music when I go somewhere far away, sometimes I watch movies, go online or chat in ICQ at the same time. Many are surprised when they find out that I am not even at the computer now.
At the expense of quality, this is all relative. How more expensive phone, the better the sound quality. On my phone, the music sounds very good, but on the CX75 it is disgusting. Although the sound is leveled in the headphones.
advanced phones have a higher capacity, so they can hold out without recharging no less than mp3-players, and besides, they also call. And try to call the player
The main thing is that he combines all this in himself.
Naturally, this is something more. Only 10 percent of them take full advantage of this something big, the rest do not even suspect what functions are in his phone. So it depends:
- from age. For example, my grandmother does not even know what a phone book is and how to enter it, calls are made using hot keys
- from the kind of occupation of a person. For example, it is rare for a business person to sit and play games.
- and, accordingly, from the phone itself. Agree, the possibilities, for example SimensA50, are limited by sending SMS, squeaking calls and a couple of stupid games.
I agree that if there is a banal radio on the TV line, this is already good! Mp3-shnik - even better! To be honest, I hardly understand why there is a camera in the phone - the quality of pictures does not go as far as cameras, videos (I’d better not say anything at all - after all, not everyone has enough money for an N90 with glass optics ...) ... Games - I didn’t think about it - I don’t I never got to them, but .... There are a couple of programs - the first - AntiMoskito - REALLY scares away mosquitoes! And the second - a reader for books in txt format - is also the question of long trips. So the telephone is not only a means for calls and SMS.
(And if you also remember that my old 5100 had a full-fledged flashlight to its dust and moisture resistant body - it's just an irreplaceable thing in a hike and a dark entrance!)
I just need to call ... I don't even text ...
I only need a phone to call, even dialing sms
As a child, after reading the story "The Old Man Hottabych", I was especially impressed with how Hottabych, with the flick of his left hand, creates a telephone "from a single piece of the finest black marble." True, this phone had one drawback - it did not work: “In that case, it’s clear why this phone doesn’t work,” Volka said. - You only made a mock-up of the phone, without everything that is supposed to be inside. And the most important thing is inside the apparatus ”. It was then that I was interested in the question of what is inside the phone. One such telephone - though not made of marble, but made of Bakelite - was on my parents' desk, and I, driven by curiosity, took it apart. After assembly, I had a lot of unnecessary parts, and my parents had to buy a new phone.
Processor: 1.2GHz 64-bit Qualcomm Snapdragon MSM8916 processor // Operating system: Android KitKat 4.4 // RAM: 2GB // Internal storage: 32GB // Display: 5-inch (1280 x 720) HD Super AMOLED with Gorilla Glass 3 // Cameras: 13MP rear with PureCel sensor and OIS, 8MP front camera with LED flash // Sound: 1 speaker, 3.5mm stereo output // Supported communication standards: LTE ( 4G), FDD Band 1,3,7,20; DL 150Mbps / UL 50Mbps, WLAN: WiFi 802.11 b / g / n / ac // Battery: 2300 mAh (lithium polymer), non-removable // Number of SIM cards: 2 micro-SIM // Colors: platinum, gold, gray graphite // Dimensions (W x D x H): 146 x 71.7 x 6.9 mm Weight: 129 g.
Over the past three decades since that time, technology has changed significantly. Inside the Lenovo S90, you won't see what I saw: no carbon microphones, no magnets with wire coils and cardboard speaker cones, no pulse dial with gears, a spring and a split flywheel of a centrifugal rotational speed regulator. In a modern smartphone, there are not so many parts into which it can be disassembled - they are arranged in rather large non-separable units, and the parts are packed inside the case extremely compactly. It is not always possible to disassemble and then assemble your smartphone on your own. So Popular Mechanics did it for you.

Mobile phones and smartphones are experiencing a peak in popularity today. To modern man it's hard to imagine your daily life without these smart devices that allow you to get in touch with the right person... But ordinary mobile phones are gradually giving way to smartphones. Let's figure it out who needs a smartphone and why and what is it Unlike mobile phone .
So, a smartphone is essentially a smart phone that, in addition to calls and SMS, has a number of additional functions... Unlike phones, smartphones have an operating system that allows them to perform tasks that are not available on regular mobile phones.
However, many today use a smartphone not as a multifunctional device that makes life much easier and solving urgent problems, but as a certain attribute of the image indicating the status of the owner.
What is a smartphone for?
So, why buy a smartphone and what functionality do modern models of these smart devices offer?
Calls and SMS
Like mobile phones, smartphones make calls on GSM networks and send SMS. Today, this is their main difference from netbooks, tablets and other portable devices.
Play music and video files
Perhaps this is the most significant the difference between smartphones and simple mobile phones.
We all remember the first multimedia models from Samsung, Nokia, which supported audio files and videos in the ".3gp" format. Today, the limitations and minimalism of these models have already pushed them to the background in the popularity rating. Modern smartphone models support almost any audio and video format. High resolution screens, large diagonal of the latest models of smartphones - perfect option to watch the video. As far as listening to music is concerned, the owners of smartphones are not limited, as before, to 500 megabytes of memory cards. Some modern smartphones can store up to 64 gigabytes of different media files.
Photo and video filming
The resolution of photo and video cameras, which was once used by old models of cell phones, today can only be found on the front camera of smartphones used for video communication. Modern smartphones allow you to shoot more quality video and take photos than camcorders and cameras. In addition, smartphones have an undeniable advantage: they are almost always at hand. This means that you can capture the best moments of both business and friendly meetings.
Internet access
For what exactly need a smartphone business people is the ability to connect to the Internet via Wi-Fi or mobile communication.
Regardless of the operating system installed, each smartphone model is equipped with a mobile browser that allows you to connect to the Internet.
In terms of ease of use, new models of smartphones are not inferior to personal computers. In addition, their portability and mobility, the lack of attachment to a specific location make these smart devices just a godsend for a business person.
Smartphone for business
Let's take a closer look at the Internet toolkit that turns a smartphone into a reliable assistant for a business person.
Using a smartphone, you can send letters, documents, photos to business partners, colleagues or just friends. To do this, you only need mobile Internet or Wi-Fi.
Video communication
Skype, FaceTime, Google Talk and many other services are designed for easy communication with partners not only through voice communication and text messages, but also with the use of a front-facing video camera, which allows you to see the interlocutor, and the interlocutor - to see you.
Messengers for business
For quick communication with business partners you can use instant messaging services ICQ, Jabber, IRC. But in the first place in terms of ease of use and popularity is the mobile messenger WhatsApp.
All types of instant messengers and video calls are completely free. You will only need to pay for using the internet. Considering the cost of calls and SMS made through the channels of mobile operators, this is great option cost savings.
Use of social media
Today it is impossible to imagine business promotion without social networks. From smartphones social media can be used both through a mobile browser and with the help of client applications specially developed for these purposes, in which the functionality of social networks is perfectly optimized for mobile devices with a touch screen.
Mobile applications for smartphones
Apps are special mini-programs designed for mobile operating systems that provide truly unlimited possibilities. These are various databases, organizers, navigators, guides, games, programs. They can be downloaded and installed using app stores - special internet services for smartphone operating systems. Almost all popular applications are free or distributed at minimal prices.
With the release of the next generation of mobile devices, the line separating smartphones from ordinary mobile phones is becoming less and less noticeable. Sometimes it's just impossible to figure it out on your own, what is the difference between a smartphone and a phone... And yet, let's try to do it.
The main differences between a smartphone and a mobile phone
Operating system availability. Smartphones have a processor so that you can install an operating system on these devices. Today the most popular operating systems for smartphones are Android, iOS, PalmOS, Bada, SymbianOS, Windows Mobile. Many people mistakenly consider the ability to download Java applications to the phone as having an operating system, which is not true. Java technology is not an operating system, but a virtual machine that runs the operating system of a phone. In almost all cases, it is closed (that is, it is impossible to make changes to it).
Multifunctionality. The set of functions that cell phones are equipped with, as a rule, include ordinary voice conversations, the ability to send SMS messages, the use of photo and video cameras and playing music tracks. For the sake of fairness, it should be noted that in modern models of cell phones the functionality is significantly expanded. So, you can watch videos, play different games, connect to the Internet, including using Wi-Fi.
All of these functions are available in smartphones, but the capabilities of these devices are significantly expanded by the presence of a file manager, organizer, archiver, programs for reading and editing files of any format, a GPS module, the ability to download programs from other developers and a number of other functions.
Important the difference between a smartphone and a mobile phone is multitasking, or the ability to use multiple programs at the same time. In ordinary cell phones, they are launched one after the other.
Why do you need a smartphone for business? The answer to the question is obvious: this is a real personal computer in your pocket.
External characteristics. Dimensions are usually the main parameter, distinguishing a smartphone from a mobile phone... As a rule, smartphones are always larger than mobile phones. However, the rapid development of technology has contributed to the fact that the difference between these devices in this parameter is becoming less obvious.
Smartphones have a large display, and modern models it is almost always touch-sensitive. The dimensions of the screen make it very convenient to work from the point of view of the clarity of the displayed information.
Working with documents, searching or chatting on the Internet, watching videos and listening to audio files - everything becomes much more convenient with a high-quality screen with a large diagonal.
Operational reliability. How more smartphone differs from phone? Less operational reliability. This is perhaps the only parameter by which ordinary mobile phones are clearly superior to smartphones. If you drop to the floor or flood cellular telephone, it won't stop working. As for smartphones, they can deteriorate even from the slightest physical impact. Plus, repairing a smartphone is much more expensive than repairing a mobile phone. Therefore, acquiring smartphone for business or just for personal use, keep in mind: they need to be handled very carefully.
Very often, when it comes to an IP phone, people are interested in the number of lines that the device has. At the same time, the selection of the number of lines on the phone is based on who will have this same phone.
For example, a telephone with 4 lines is enough for a secretary of a small company, and it is not a fact that all lines will be used if the flow of calls is not so large.
In this article, I would like to consider how these lines can be used in a standard way, and how they can be used if there is only one registration and they are idle. For example, 2 phones are used, Linksys SPA 525 and Yealink SIP-T22.
Lines in the standard sense
There is an assumption that the original idea of the lines was to register different SIP operators for each line. This is convenient when there is no PBX and the phone is connected directly to the Internet. That is, our actions are as follows:1) Choose the desired line on the phone
2) Dial the number
3) We call through the selected line
With an incoming call, the line of the operator from whom the call came will light up accordingly.
In another case, the most common one, there is only one SIP server (our IP-PBX), and there is only one registration, and the buttons are needed to conveniently display the status of the held conversation / the ability to receive another incoming call. If the phone is declared 5-channel, like our SPA 525, and we rarely have more than 2 simultaneous calls, the rest of the buttons are idle and only waste electricity.
In the web interface, it looks like this: 
Reconfiguring line buttons
There is a way to assign these same buttons to certain actions since they are claimed to be programmable.To do this, we need to go to the phone's web interface, switch to Admin / advanced mode and in the Phone section specify the mode and the line:
Thus, we get a new function on the previously "useless" button: blf (Busy Lamp Field, or displaying the busy line) and sd (Speed Dial, speed dial). You can also configure cp (call pickup, i.e. when you call through a special code, you can pick up the call). For all this to work with our Asterisk, it is also important to specify the type of server, this is done in the Att Console section. There are other servers on the list such as broadsoft and spa9000.
I must say that on SPA 94x phones this setting is on the same page, and why on SPA525 it was moved to such an obscure place is not clear.
For special aesthetes, Linksys allows you to customize the type of blinking and reaction to events.
After this setting, when talking to 209, the button on the phone lights up red. If a call arrives at 209, the line button blinks. And if you press the button, a call is made to number 209. This becomes especially convenient when you often need to transfer calls to the same number.
Further phone goes Yealink brand, SIP-T22. Has 3 line buttons, and 3 registrations. 
In terms of configuration, everything is much simpler, it is located in the Phone-DSS-Line buttons menu.
At first, the drop-down list is generally striking in its length: 
Well, the setting itself: 
The result of this action is less beautiful than on Linksys phones, but it completely fulfills its functionality:
if there is no conversation, the line button is constantly on; if a call came to 233 - the button blinks frequently; if a conversation is active, the button blinks slowly. Well, of course, when you press this button, a call is made to number 233.
Conclusion
Hopefully this information will seem useful, and will explain the purpose of the lines, since sometimes you had to meet "wild" options, when 4 different internal numbers were set up on one 4-channel phone, which is why the calls begin to behave in a very strange way :)People are starting to ask the question more and more often how is it programming on the phone? Is it convenient or not? Probably every novice programmer who strives for knowledge and wants to program everywhere and always asked himself all these questions. Of course, this was influenced and so fast development technologies. In a short period of time, typewriters have been replaced by laptops and PCs, which are capable of solving very complex problems.
If we look at the development of phones in general, they also started to develop very quickly. First touch phones they did not take it as it should, and now such a smartphone is an integral part of every person. This is the answer to the question: “ Programming on the phone - where do people get such questions and thoughts from?“. Almost every person who is at least somehow familiar with programming will say that programming on Android or Apple smartphones is extremely inconvenient and unnecessary. They will be partly right, but it is still possible and let's figure out how and why?
Programming on the phone - shall we figure it out?
Programming on the phone is a long and complicated process, which does not bring as much fun and inspiration as with the same programming on a PC or laptop. However, it often happens that there is no way to take a laptop with you, but the task must be completed or you just want to program. In such cases, the phone can help out.
Like this? Programming on the phone using various services and software.
There are many services out there that help you program on anything. The main thing is access to the Internet and a display with an input device. One of these services is the very popular Ideone.
Ideone is an online compiler and debugging tool that allows you to compile from source and run it online in over 60 programming languages.
Such online services allows you to compile the code without any problems, which you can write in the same place. The choice of programming languages is usually extensive and constantly updated. At least new versions of programming languages are being added.
Also, there are highly specialized programs such as Java Compiler, etc. They can be downloaded to your smartphone without any problems. Phone programming and consists in such programs and services, since it will be extremely inconvenient to do this in the terminal. One of the best terminals on Android is.
Why program on the phone. Convenience and final answer.
As you might have guessed, programming on the phone- this is extremely inconvenient due to the small screen and the lack of a full-fledged keyboard. Sure, you can connect the keyboard via OTG, but why? Why not take a laptop in this case, because the keyboard you have with you?! Another factor that speaks against programming in Android phones and Apple is the lack of professional software. There are only highly specialized compilers or online IDEs. As you can imagine, they can never replace normal software for a programmer.
My opinion is that programming on a smartphone does not make sense, as it takes a lot of time and concentration. This is certainly possible and may even be useful to someone. However, I believe that it is better to study material that can help you in development, since a smartphone is very suitable for this. On the way somewhere or lying on the couch, you can always watch a video course or read a book. Use your gadgets correctly, and I hope I was able to give you an answer to this, albeit an easy, but very popular question.
