Which system is an intelligent system?

Smart phone is a kind of mobile phone with stronger computing power and function than traditional mobile phone. The most commonly used operating systems are: Symbian, Windows Phone 7, iOS, Android and BlackBerry OS. Their application software is incompatible with each other. Because you can install third-party software like a personal computer, smart phones are rich in functions. Nowadays, the mobile phone is more than just a communication tool. Under the trend of intelligent system, mobile phones have become multimedia intelligent mobile terminals: some people like to use their mobile phones to QQ, play Weibo and read web pages; Some people like listening to songs, taking photos and playing games. Some people use mobile phones to arrange their schedules and work. ...................................................................................................................................... ............................... Today, let's compare the above five mainstream mobile phone systems and see which one suits you best. As the king of smart phones, Symbian, the emperor of yesterday, was once coquettish from 2005 to 20 10. Many Nokia Symbian phones, N70-N73-N78-N97, were shot in the street, and Nokia N series was once called "N= infinite" phones. Basic hardware level, simple operation, power saving and abundant software resources are the important characteristics of Symbian system mobile phones. In the domestic software development market, basically every software will have a corresponding Symbian mobile phone version. The initial goal of Saipan's development is to ensure long-term stable and reliable operation on low-resource equipment, which leads to steep learning curve and high development cost of Saipan's application development. But the running efficiency of the program is very high. For example, the 5800 128M RAM can run 10 programs in the background at the same time, running smoothly (multi-tasking function is particularly powerful), and its remaining memory remains stable even if it is not turned off for several days. Although under the siege of Android and iOS, Nokia launched Symbian 3 system, and even updated it (Symbian Anna), which has significantly improved the external user interface and internal functional features, such as new form parts that can be customized freely, more home screens and new drop-down menus. Due to the lack of support for emerging social networks and web 2.0 content, the market share of Saipan smartphones is shrinking. At the end of 20 10, its market share has been surpassed by Android. Since the end of 2009, major manufacturers, including Motorola, Samsung Electronics, LG, Sony Ericsson, etc., have announced the termination of the research and development of Symbian platform and turned to the Android field. 20 1 1 At the beginning of the year, Nokia announced that it had formed a strategic alliance with Microsoft to launch a smartphone based on Windows Phone, and in fact gave up Saipan, which had been in business for many years, and the delisting of Saipan was a foregone conclusion. The current trend-the word-Android Android first appeared in the science fiction novel L'ève future published by the French writer August Villiers de Le-Adam in 1886. He named this machine that looks like a human a robot. Since HTC and Google jointly launched the first Android mobile phone G 1 in 2008, in the first quarter of 20 1 1, the global market share of Android surpassed Saipan system for the first time, ranking first in the world. According to the data of 20 1 1 year 1 1 month, Android accounts for 52.5% of the global smartphone operating system market and 58% in China. Now Android has become the mainstream smartphone operating system on the market, and this kind of green robot can be seen everywhere. Why is Android so popular in such a short time? 1, open source. This is the most critical factor for the rapid growth of Android. Before Android, no intelligent operating system was as open source as Android. The open source of Android breaks the authorization mode of the previous operating system platform, which not only reduces the cost of manufacturers, but also gives them more room to play freely and enhances their enthusiasm for supporting Android, which is the source of the rapid maturity and growth of Android platform. 2. Alliance. Alliance strategy is another magic weapon for Android to attack the city. Symbian has also adopted alliance strategy, but due to insufficient open source, bloated system and unsustainable, partners have left the camp. From the perspective of alliance members, Symbian Alliance is mainly a mobile phone manufacturer. Open handset alliance (OHA) founded by Google for Android is supported not only by many big-name mobile phone manufacturers such as Motorola, Samsung, HTC and Sony Ericsson, but also by mobile phone chip manufacturers and mobile operators, with only 34 founding members. Open source and alliance, Android embodies the power of almost the whole world, which is the fundamental reason why the image and voice of Android can spread to every corner of the global mobile Internet market. 3. technology. The bottom operating system of Android system is Linux. As a free and easily available operating system, Linux has absorbed the essence of countless programmers around the world. This is the biggest reason why Android system is more extensible than Symbian. In addition, as an embedded operating system, Linux makes Android easy to be applied, transplanted to various platforms and developed rapidly. At the same time, the faster version update speed of Android platform makes the hardware performance of mobile phone develop in the optimal direction, and also makes the characteristics of Android playable, fun and easy to play more and more obvious. Android models are bulky, easy to use and quite free. The system allows manufacturers and customers to easily customize various Roms, desktop components and theme styles. The simple and gorgeous interface has been recognized by our customers, and brushing mobile phones is also something that many Android users talk about. Unfortunately, there are many versions of Android, and there are various versions of Android phones on the market at the same time, such as 1.6, 2.0, 2. 1, 2.2, 2.3. The compatibility between application software and system versions is a big challenge for program developers. At the same time, due to the low development threshold, although there are many applications, the application quality is uneven, and even a large number of malicious software appear, resulting in some users suffering losses. At the same time, Android has no restrictions on the hardware of various manufacturers, which leads to poor experience of some users on low-end models; On the other hand, because the application of Android is mainly developed in Java language, its running efficiency and hardware consumption have been criticized by other mobile phone users. Android has been updated to version 4.0. Noble and gorgeous-IOS IOS, as the operating system of Apple's mobile devices iPhone and iPad, has become one of the leading operating systems in the world under the impetus of App Store. Initially, this system was called "iPhone OS", and it was renamed as "iOS" at the WWDC conference on June 7, 20 10. The user interface of iOS is based on the concept of direct operation through multi-touch. Control methods include sliding, touch switch and key. Interaction with the system includes sliding, tapping, squeezing (usually used for zooming out) and reverse squeezing (usually used for zooming in). In addition, through its own accelerator, its rotating device can change its Y axis to change the direction of the screen, which makes the use of iPhone more convenient. The earliest iPhone OS 1.0: Built in the first generation of iPhone, with the smooth touch screen of iPhone, iPhone OS brought excellent experience to users, which can be described as amazing compared with the mobile phones at that time. IPhone OS 2.0: With the release of iPhone 3G, App Store was born. App store provides a convenient and efficient software sales platform for third-party software providers, and builds a bridge of communication and sales between software developers and end users, thus greatly enriching the functional applications of iPhone. IPhone OS 3.0:iPhone 3GS began to support copy and paste. IOS officially started: iOS 4. When the iPhone4 went on the market, Apple decided to rename the original iPhone OS system "iOS" and release a new generation of operating system: "iOS 4". This version officially supports multi-tasking function, which is realized by double-clicking the HOME key. IOS5: Siri voice operation assistant function has been added, and users can interact with their mobile phones. This function can realize the user's voice recognition and complete some complicated operations. Siri is used to query weather, navigate, ask time, set alarm clock, query stocks and even send short messages, which is convenient for users. From the original iPhone OS to the latest iOS system, iOS has become Apple's new mobile device operating system, spanning iPod Touch, iPad and iPhone, and becoming Apple's most powerful operating system. Even the new generation of Mac OS X Lion has borrowed some designs from the iOS system. It can be said that iOS is another successful operating system of Apple, which can bring excellent user experience. Excellent system design and strict App Store, iOS is the most widely used mobile device operating system, coupled with strong hardware support and the latest iOS5 built-in Siri voice assistant, it will undoubtedly greatly enhance the user experience and feel the benefits brought by technology. However, devices using iOS are generally more expensive than other devices and are not attractive to novices. Moreover, Siri can only be used on iPhone4s for the time being, and does not support Chinese. In China, it can only be chicken ribs. Brand-new-Windows Phone As early as 2004, Microsoft began to develop an important version update of Windows Mobile code-named "Photon", but the progress was slow, and finally the whole plan was cancelled. It was not until 2008, under the impact of iOS and Android, that Microsoft reorganized the team of Windows Mobile and continued to develop new mobile operating systems. It was originally planned to release the official version in 2009, but many delays made Microsoft decide to use Windows Mobile 6.5 to make the transition first. The development of Windows Phone can be accomplished overnight. One of the consequences is that the old Windows Mobile application can't run normally in Windows Phone system. Terry Myerson, vice president of Windows Phone development department, said: "In order to improve the experience of Windows Phone 7 by not using stylus, using capacitive touch screen and other hardware changes, we have to break the application compatibility of Windows Mobile 6.5." As the successor of Windows Mobile, Windows Phone uses a new user interface called "Metro", which is very similar to Kin that Microsoft has stopped. Its home screen, also known as the "start screen", consists of many square or rectangular figures and elements called "movable tiles". Dynamic bricks are equivalent to buttons that can be linked to applications, functions and other independent components, such as contacts, web pages or media items. Users can add, rearrange or delete dynamic bricks by themselves. Even when the device is locked, the dynamic brick can be updated at any time according to the content it represents-for example, there are several unread emails on the dynamic brick of e-mail; Or the weather dynamic brick can also display the weather content updated in real time. At present, dynamic bricks only support vertical layout and cannot be displayed in landscape mode. The brand-new Windows mobile phone combines the advantages of network, personal computer and mobile phone, allowing people to enjoy the desired experience anytime and anywhere. The built-in office suite and Outlook make office more efficient and convenient. In terms of application, although Windows phone provides a good development tool, and in order to standardize the user experience of Windows Phone 7, Microsoft has imposed strict constraints on developers to develop applications, and developers must develop applications in strict accordance with these development constraints and terms. For example, developers cannot develop applications involving mobile phone cameras; Developers can't customize the interface of the application privately; Applications involving system classes must use the interface provided by the system to run; Developers must send the developed applications to mobile phones through Zune synchronization function, but the number of Windows phone applications is still very small. On the one hand, Windows phone has a unique interface and few places to customize, which is easy to cause aesthetic fatigue; On the other hand, in the latest version of Windows Phone 7.5, although multitasking is supported, only five programs can be run at most, and multitasking is not enough. Windows Phone started early and developed slowly. Nevertheless, at present, Windows Phone7 has been applied to Nokia mobile phones, and has been introduced to the market as the main system of Nokia mobile phones. High-end business -Blackberry OS Blackberry system, namely Blackberry System, is the operating system of wireless handheld e-mail solution terminal equipment launched by Research In Motion (RIM for short) in Canada, and independently developed by RIM. Different from Symbian, Windows Mobile, ios and other operating systems used by other mobile phone terminals. Blackberry system has stronger encryption performance and is more secure. Blackberry with BlackBerry system not only refers to a mobile phone, but also includes the Push Mail real-time email service launched by RIM, including server (email setting), software (operation interface) and terminal (mobile phone). BlackBerry mail equipment is based on two-way paging technology. Combined with RIM's server, the device relies on specific server software and terminals, and is compatible with existing wireless data links, thus realizing the dream of sending and receiving mail from all over North America anytime and anywhere. This device does not catch people's eyes and ears with wonderful pictures and color screens, and even has no sound generator. After the "9 1 1" incident, there was a craze for owning blackberry terminals in the United States because the blackberry delivered the information of the disaster site in time. The most important principle of Blackberry's success is to provide an integrated solution for enterprise mobile office for senior white-collar workers and business people. Enterprises have a lot of information that needs to be processed immediately, and they also need a wireless and movable office equipment when traveling. As long as the enterprise installs a mobile gateway, a software system, and uses the mobile phone platform to realize seamless links, employees can use their mobile phones to work anytime and anywhere. Its greatest convenience is that it provides the push function of mail: that is, the mail server actively pushes the received mail to the user's handheld device, without the user frequently connecting to the network to check whether there is any new mail. Blackberry system has excellent stability, and its unique positioning is also favored by business people. But there is no advantage in the mass market, and there are few domestic users and application resources.
