What is the consciousness of a smartphone? Please explain it to me. I don’t quite understand?

What is a smartphone? To put it simply, it is a simple "1+1=" formula, "PDA + mobile phone = smartphone". Broadly speaking, in addition to the call function of a mobile phone, a smartphone also has most of the functions of a PDA, especially personal information management and browser and email functions based on wireless data communication. Smartphones provide users with sufficient screen size and bandwidth, which are convenient to carry around and provide a broad stage for software operation and content services. Many value-added services can be launched here, such as: stocks, news, weather, transportation, commodities, Application downloads, music picture downloads, and more. Smartphones integrating 3C (Computer, Communication, Consumer) will surely become the new direction of mobile phone development in the future.

Determining whether a mobile phone is a smartphone does not depend on whether it supports MP3, whether it supports HTML page browsing, whether it supports external memory cards, etc., but whether it has an operating system. mobile phone. In other words, we need to look at the program scalability of the operating system and whether it can support the installation and application of third-party software.

There are currently four different operating systems for smartphones on the market, which are:

1. Symbian operating system (UIQ, Series60, Series80, Series90)< /p>

2. Windows Mobile (PocketPC, Smartphone)

3. Linux operating system

4. Palm operating system

5. Domestic research and development Production 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 today, and has considerable There are many interfaces for different users, which are often referred to as Series. Regarding the interface of the Symbian operating system, many people are always confused about its division rules. Next, we will briefly introduce the typical characteristics of each system version.

Let’s first clarify a concept: whether it is Series60, Series80, Series90 or UIQ, they are all interfaces developed based on the Symbian platform, and each is distinguished based on some hardware characteristics. It is rumored that Nokia may launch Series50 and Series100 interfaces, but its authenticity cannot be determined yet.

Series60

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

The most intuitive factor that distinguishes Series60 is the screen resolution. The resolution supported by Series60 is 176*208 pixels, but in the future, Series60 will also support 240*320 pixels, 352*416 pixels, etc.

The Series60 interface is the interface with the most third-party software or games, and it has naturally become the Series most frequently used by smartphones with the Symbian operating system.

I won’t list all the mobile phone models that use the Series60 interface here. A considerable number of Nokia’s smartphones alone use the Series60 interface.

Series80

The easiest way to identify the Series80 interface is to see if the phone supports QWERTYKEYBROAD. For example, Nokia's high-end series 9210, 9300 and even 9500 all use QWERTYKEYBROAD. The screen resolution of Series80 is also a relatively special 640*200 pixels.

Series90

Series90 is the youngest interface on the Symbian platform. Only Nokia 7700 and 7710 mobile phones support Series90.

The easiest way to identify the Series90 interface is: the Symbian smartphone 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 games and entertainment. However, because there are too few mobile phone models using the Series90 interface, the support of third-party software is not very strong. , so Series60 should still be the preferred interface for players.

Windows Mobile operating system

To be precise, Windows Mobile is not an operating system, it is just a brand owned by Microsoft.

The predecessor of Windows Mobile is Windows CE launched by Microsoft in 1996. In the second quarter of 2000, Microsoft Windows CE officially broke away from its dependence on Palm and renamed Windows CE to Windows Pocket PC (the abbreviation is what we often call PPC). , and then began its marriage with smartphones.

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

Linux operating system

Although Symbian has occupied half of the smartphone market, the seemingly weak Linux operating system also has quite outstanding advantages. Its advantages are reflected in the following points:

1. The Linux operating system used on smartphones and the Linux operating system we often say used on computers are the same system, and both are completely free operating systems. . Being free on the operating system is equivalent to saving the production cost of the product.

2. The Linux operating system has a low system resource usage and relatively stable performance, which is recognized by everyone. If you compare the system resource usage of the Linux platform with the huge Windows Mobile, the results can be imagined.

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

However, the Linux operating system is not perfect. Since the Linux operating system entered the field of smartphones relatively late, the mobile phones using this operating system are basically only a small number of Motorola models (such as A780, E680, A768i), so there are very few third-party software specifically made for these small numbers of users. It has affected the expansion of Linux operating system in the field of smartphones.

Palm Operating System

A mobile phone using the Palm operating system is actually just a "handheld computer with mobile phone functions". Its operating system is no different from previous handheld computers based on the Palm operating system. the difference.

In the field of smartphones, those who use the Palm operating system are non-mainstream manufacturers, such as HP. Although Samsung has launched SCH-i539, its prospects are not promising.

Such a 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 and implemented through third-party software. This method of operation is obviously much worse than Symbian and Linux. Therefore, the development of Palm operating system in the field of smartphones has not been smooth sailing. It’s no wonder we call it “a handheld computer with mobile phone functions” rather than “a mobile phone with handheld computer functions”.

Several things that smartphones have to remind you

1. Viruses.

Smartphones, like the desktops and laptops we use every day, are based on an open platform, so getting infected by viruses only takes a matter of minutes. In view of this, backing up important data at any time is a must-do when using a smartphone.

2. Crash. Since it is an open operating system similar to the desktop Windows XP, it is common for it to crash when interfered by illegal programs. So it is best not to install various application software wantonly. In addition, if you install too many software and save too many documents, the data reading and writing speed of your mobile phone will also slow down, which is the same as the "crash".

3. Power consumption. The power consumption of smartphone CPU, screen and other hardware cannot be ignored. These hardware can easily run out of power. In addition, today’s smartphones are becoming more and more fashionable and thin, and their small battery capacity is Even more pitiable. There is no solution in this regard. We can only remind smartphone users not to play with their phones all the time (Zhou Meng).

The following is our opinion on smartphones:

Computers cannot be used as mobile phones, mobile phones can be used as computers. In mobile commerce, wireless entertainment, handheld Internet, calls, text messages, Watch animations, listen to songs, QQ, MSN, take photos, edit Word documents, browse the web, send and receive emails... These functions make it fun for you to use them with you. It has the guts of a computer. The perfect combination of the two, this is a smartphone. (Smartphone);

If the mobile phone market in 2003 was a "colorful year", then 2004 and later will be a "smart phone year". After more than 10 years of development, mobile phones have returned from their original aristocratic status to a communication tool for mass communication, and their functions have also expanded from a single call to intelligence and other aspects. Today's smartphone industry seems to be brewing a storm. Smartphones will bring new changes to the traditional structure of the entire mobile phone industry. Smartphones will be integrated into PDAs, digital cameras, game consoles, MP3 music players and other consumer electronics. product functionality.

As a mobile information terminal product that integrates voice communication, multimedia and handheld computer functions, smartphones were originally born from handheld computers. Smartphones first appeared in 1999, when Motorola The Tiantuo A6188 mobile phone launched at the end of the year is the world's first mobile phone with a touch screen and Chinese handwriting recognition input, and is known as the originator of smartphones.

In order to let everyone better understand smartphones, we have specially made an overview of smartphone development - click to view the smartphone chronicles.

Finally, what we want to say is that smartphones are currently high-end products in the mobile phone industry. They are not only products owned by senior white-collar workers and boss-level people. It is foreseeable that smartphones will become "from the aristocracy". "Altar" comes down and enters the hands of mass consumers! I believe that today or tomorrow, it will be in your and my hands!
