What is the consciousness of smart phones? Tell me, I don't quite understand.

What is a smart phone? Generally speaking, it is a simple formula of "1+1=" PDA+mobile phone = smart phone ". Broadly speaking, smart phone not only has the function of talking on mobile phone, but also has most functions of PDA, especially personal information management based on wireless data communication, browser and email functions. Smart phones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also provides a broad stage for software operation and content services. Many value-added services can be introduced in this respect, such as: stock, news, weather, transportation, goods, application download, music and picture download, etc. 3C (computer, communication, consumption) smart phone will surely become the new direction of mobile phone development in the future.

Judging whether a mobile phone is a smart phone depends not on whether it supports MP3, HTML page browsing, external memory card and other functions, but on whether it has an operating system. In other words, it depends on the program expansibility of the operating system and whether it can support the installation and application of third-party software.

There are four different smartphone operating systems in the market, namely:

1, Symbian operating system (UIQ, 60 series, 80 series, 90 series)

2. Windows Mobile (PDA, smart phone)

3.Linux operating system

4.Palm operating system

5. Domestic R&D operating system

Symbian operating system

Needless to say, everyone can feel that Symbian operating system is the most widely used operating system in the field of mobile phones, and there are quite a few interfaces for different users, which is often called series. Regarding the interface of Symbian operating system, there are always many people who are at a loss about its division rules. Next, briefly introduce the typical characteristics of each system version.

Firstly, a concept is defined: Series60, Series80, series 90 and UIQ are all interfaces developed based on Symbian platform, and then they are distinguished according to some hardware characteristics. It is rumored that Nokia may launch Series50 and Series 100 interfaces, but its authenticity is still uncertain.

Series 60

Series60 is the most widely used system version in Symbian smartphones. Series60 system is also divided into three versions: Symbian 6.0OSSeries60, Symbian 7.0 OS Series60 and Symbian 8.0 OS Series60.

The most intuitive factor to distinguish Series60 is the resolution of the screen. The resolution supported by Series60 is 176*208 pixels, but in the future, Series60 will support 240*320 pixels, 352*4 16 pixels and so on.

Series60 interface has the most third-party software or games, so it naturally becomes the most frequently used series of Symbian operating system smartphones.

The models of mobile phones using Series60 interface are not listed here. Only a considerable part of Nokia's smartphones use the Series60 interface.

Series 80

The easiest way to identify the Series80 interface is to see if the mobile phone supports QWERTYKEYBROAD. For example, Nokia's high-end series 92 10, 9300 and even 9500 all adopt QWERTYKEYBROAD. The screen resolution of Series80 is also special 640*200 pixels.

Series 90

Series90 is the youngest interface on Symbian platform, and only Nokia 7700 and 77 10 phones support Series90.

The easiest way to identify the Series90 interface is that Symbian smartphones will use a touch screen with a resolution of 640*320 pixels.

Judging from the hardware parameters of Series90, it should be the strongest platform for mobile game entertainment. However, because there are too few mobile phones with Series90 interface and the support of third-party software is not very strong, Series60 should still be the first choice for players.

Windows Mobile operating system

Accurately speaking, Windows Mobile is not an operating system, but a brand owned by Microsoft.

The predecessor of Windows Mobile is WindowsCE introduced by Microsoft in 1996. In the second quarter of 2000, Microsoft WindowsCE officially broke away from its dependence on Palm, renamed Windows CE as WindowsPocketPC (abbreviated as PPC), and then began to marry smart phones.

In 2003, Microsoft developed Pocket Phone Edition and Windows PoweredSmartPhone operating system, and the integration of the two is the strict sense of Windows Mobile.

Linux operating system

Although Symbian has occupied half of the smart phone market, the seemingly weak Linux operating system also has quite outstanding advantages. Its advantages are as follows:

1, the Linux operating system applied to smart phones and the Linux operating system we often say applied to computers are a system, and both are free operating systems. Free on the operating system means saving the production cost of the product.

2. It is generally believed that Linux operating system has low system resource occupancy and stable performance. If the system resource occupation of Linux platform is compared with the huge WindowsMobile, the result can be imagined.

3. The integration of 3.Linux operating system and JAVA is unmatched by any operating system. The application mode of Linux+JAVA can give users a lot of room for expansion.

However, the Linux operating system is not perfect. Because the Linux operating system entered the field of smart phones late, only a few mobile phones (such as A780, E680, A768i) use this operating system, so there are very few third-party software specially customized for these small users, which affects the expansion of the Linux operating system in the field of smart phones.

Palm operating system

The mobile phone with Palm operating system is actually a "handheld computer with mobile phone function", and its operating system is no different from the previous handheld computer based on Palm operating system.

Palm operating system is adopted by some non-mainstream vendors in the field of smart phones, such as HP. Although Samsung introduced the SCH-i539, its prospects are not good.

The low evaluation of Palm operating system smartphones is largely due to its scalability. Although the Palm operating system has been developed for a long time, many of its functions need to be coordinated by third-party software, which is obviously much worse than Symbian and Linux. Therefore, the development of Palm operating system in the field of smart phones is not smooth sailing. No wonder we call it "PDA with mobile phone function" instead of "mobile phone with PDA function".

A few things that smart phones have to remind.

1, virus. Smartphones, like the desktops and notebooks we use every day, are based on an open platform, so it is only a matter of minutes to get infected with the virus. In view of this, always back up important information and the work that must be done when using smart phones.

2. collapse. Because it is an open operating system with the same nature as desktop WindowsXP, it is common to crash when disturbed by illegal programs. So it is best not to install all kinds of application software at will. In addition, if more software is installed and more files are stored, the data reading and writing speed of the mobile phone will also slow down, which is the same as "crash".

3. Power consumption. The power consumption of CPU, screen and other hardware of smart phone can not be ignored. These hardware are easy to run out of power. In addition, smart phones are increasingly pursuing fashion and thinness, and their small battery capacity is pitiful. There is no solution in this regard, only to remind smartphone users not to play mobile phones all the time (Zhou Meng).

The following are our views on smart phones:

Computers can't be mobile phones, but mobile phones can be computers. It can be used for mobile commerce, wireless entertainment, handheld Internet surfing, making phone calls, texting, watching animations, listening to songs, QQ, MSN, taking photos, editing Word documents, browsing the web, sending and receiving emails ... These functions make you very comfortable to use. It has the internal organs of a computer, and the two are perfectly combined. This is a smart phone.

If the mobile phone market in 2003 is a "colorful year", then the year after 2004 will be a "smart year" for mobile phones. After the development of 10 years, the mobile phone has returned from the initial aristocratic status to the communication tool of mass communication, and its function has also expanded from a single call to intelligence and other aspects. Today's smart phone industry seems to be brewing a storm. Smart phones will make a brand-new change in the traditional pattern of the whole mobile phone industry. Smart phones will integrate the functions of consumer electronic products such as PDA, digital camera, game machine and MP3 music player.

As a mobile information terminal product integrating voice communication, multimedia and PDA functions, smart phone was originally born in PDA and first appeared in 1999. At the end of that year, Motorola launched Tiantuo A6 188 mobile phone, which was the first mobile phone with touch screen and Chinese handwriting recognition input in the world, and was called the originator of smart phones.

In order to let everyone know more about smart phones, we made an overview of the development of smart phones-click to view the chronicle of smart phones.

Finally, what we want to say is that smart phones are high-end products in the mobile phone industry. Not only senior white-collar workers and boss-level people can own products. It is foreseeable that smart phones will step down from the "altar" of the nobility and enter the hands of mass consumers! I believe it will come to us today or tomorrow!
