The word “smartphone” will surprise someone today. Even if the person didn’t use it, then he certainly heard it. From friends, advertising and a variety of sources. Today we understand what a smartphone is, how it differs from a mobile phone, and how this technique, which is extremely necessary for a modern person, is arranged. The origin of the term and function of the smartphone
Smartphone is a word composed of two “Smart” and “Phone” in English, that is, the literal translation of the word smartphone means “smartphone”. This feature accurately reflects what a smartphone is. In fact, a smartphone is a smaller computer that can perform similar functions, if not more. Most often, a smartphone is called a phone or a switch. In a way, this is correct, but there are still differences.
The phone in the classic sense is not a touch device that does not have the performance that the gadget in question does. We can say that the main task of the phone is to call, plus it can listen to music, play simple games, send pictures via mms. The functions of the smartphone are much broader. – Here is available high-speed Internet access, work with files, serious games, calls, send photos and other data in various ways, you can make very high quality photos.
Note Communicator and smartphone are very similar concepts. If you delve into the creation story, you can see that smartphones have appeared from communicators. It can be argued that the smartphone is a regular phone integrated into the communicator.
How the smartphone was created: big milestones
The idea of creating a phone with the functionality of a PC has been in the air for a long time, to be precise, this was thought of after the release of the first PDAs (smartphones 1990s).
The first smartphone appeared in 1992. – IBM Simon. To be fair, it should be noted that this is only a prototype, but far from being a full version in its current state. Two years later, he began selling at a price of $1000. The capabilities of the IBM Simon smartphone were in addition to calls: faxing, organizer, mail and games. The device was controlled by a sensor. Large weight in 1 kg. He didn’t let the phone become popular.
The second attempt – 1996. The creation of HP and Nokia – HP 700LX. In this case the apparatus consisted of two parts. – HP PDA with the ability to connect a Nokia 2110 mobile device. The software was rewritten so that the devices could work with each other. Of course, the model is not a smartphone in the classical sense and acts more like a symbiosis of two separate devices, although it can be depicted as a prototype of a modern gadget.
Later comes the Nokia 900 switch. Here both integrated devices in one case. In a closed format, the appearance of an enlarged telephone, in the open, a keyboard became available. OS – GEOS, the disadvantage of which was the lack of support for third-party programs.
In 1997 in Taiwan appears HTC. The goal – the creation of smartphones and switches.
1998 is The appearance of the sub-brand Symbian. to create a single smartphone operating system.
All these prerequisites, and the first device, which was officially named after the smartphone, appeared in 2000 – this is the Ericsson R380s. The model is almost a smartphone: touch input, small size, OS – Symbian 5.1. The only negative aspect is a closed operating system.
2001 – Nokia 9210 appears with open operating systemwhich is considered the first full-fledged smartphone.
2003 – Microsoft’s mobile OS release.
2007 – Your smartphone has created the most popular brand APPLE. The device did not have a wide range of functions, but completely lost the keyboard, and control is carried out by a sensor with support for multi-touch function. It was unprecedented for the user and, due to a very aggressive advertising campaign, the devices became bestsellers. Own OS didn’t get a chance for programmers to work on it from the outside, and they created a separate environment for them in 2008.
End of 2007 – Release of android and next year, Google announces that the source code of the operating system is opened, that is, anyone can write programs for this system.
2008 – Apple invented the first device to support third-generation networks. and navigation systems. Deliveries to 70 countries of Apple 3G, which has improved much more than the first model, allow the brand to start tapping into the market, and statistics show that 5% of all devices sold at that time belong specifically to Apple’s technique.
The same year HTC Dream appears on Android (first use of the operating system), Nokia N5800 on Symbian with touch screen.
2009 gives us the Nokia N97 – touchscreen slider and sliding the full keyboard.
Further development of devices is a change in concept, size, functions and many other things that led to the emergence of modern devices. Many believe that the smartphone came to Steve Jobs. This is not entirely true, since Jobs was able to combine the most useful functions, but perhaps his main merit is that already in 2007 he understood how to make devices and sell them to conquer the world. It’s no secret that his formula for introducing new chips and violent advertising still works. It is no coincidence that Apple sets trendsAnd, to date, almost every brand has to match or catch up with the American company. What is a smartphone
Many people do not think about the fact that in a small case of a smartphone there are a huge number of parts and assemblies that provide certain functions. The main components of the smartphone:
- housing
- processor
- motherboard
- main and operational memory;
- Battery
- Camera
- sensors;
- wireless interface modules;
- screen
This is the first thing that catches the user’s attention. It can have different sizes and shapes, but the main important parameter is performance material. It depends on ergonomics and usability. The main materials are glass, plastic, metal, ceramics. Most often, manufacturers combine these materials, and a rare device consists of only one metal or plastic. Processor
By the right heart of the smartphone. It is responsible for all actions performed on the device. In general, the processor is not the right word, as it combines several nodes: the chipset (confused with the processor), the graphics coprocessor (analog video card in the computer), as well as the peripherals that connect them. Modern chipsets are manufactured in ARM architecture according to a specific process technology. At the moment, the most modern technical process – 10 nm. Important characteristics of the processor: Number of cores and clock frequency.
The processor generates heat during operation. This means that this problem must be solved not by cooling, since the smartphone is too small, but by the processor itself: for this different working models are used, and the power consumption of the chipset is also reduced. Motherboard
This is a type of bone and circulatory system of the device. All other nodes are attached to it, and also along it signals are transmitted to a detail. RAM and main memory
RAM responsible for speed. It stores the information necessary for the immediate operation of the processor. It is often called temporary, because when the smartphone information is disabled it is not saved. RAM has a relatively small capacity compared to the main one, and at the moment in smartphones it reaches 8 gigabytes.
