What are the mobile operating systems?

Symbian system

Introduction

Symbian (Symbian) is a real-time, multi-tasking pure 32-bit operating system with low power consumption and memory footprint. It has few features and is very suitable for use on mobile devices such as mobile phones. After continuous improvement, it can support GPRS, Bluetooth, SyncML, and 3G technologies. The most important thing is that it is a standardized open platform, and anyone can develop software for Symbian-enabled devices. Different from Microsoft products, Symbian separates the common technology of mobile devices, that is, the kernel of the operating system, from the graphical user interface technology. It can well adapt to platforms with different input methods, and also allows manufacturers to make products for their own products. A more friendly operation interface conforms to the trend of personalization, which is also the main reason why users can see different symbian systems. Now Java programs developed for this platform have begun to become popular on the Internet. Users can expand the functions of their mobile phones by installing these software.

Development

During the development stage of Symbian, three branches appeared: Crystal, Pearl and Quarz. The first two are mainly targeted at the communicator market and are the ones that appear the most on mobile phones. They will be the main force in smart phone operating systems in the future. The first mobile phone based on the Symabian system was the Ericsson R380 mobile phone launched in 2000. The one that is really more mature and attracts people's attention is the Nokia 9210, which was launched in 2001, which uses the Crystal branch system. The Nokia 7650 and 3650 launched in 2002 are models of the Symbian Pearl series. The 7650 is the first smartphone product based on the 2.5G network. They both belong to Symbian version 6.0. A model launched by Sony Ericsson also uses the Pearl branch of Symbian. The version has developed to 7.0 and was developed specifically for 3G networks. The current Nokia 6630, 6681, etc. have reached 8.0, which can be said to represent the most popular mobile phones today. Powerful mobile operating system. In addition, Symbian has supported external storage devices, such as MMC cards, since version 6.0, which gives full play to its powerful expansion capabilities and makes it possible to store more software and various large-capacity multimedia files. Today, the Symbian system has developed to OS9.4, which is the fifth version of the S60 operating system. The biggest innovation is the addition of touch playability. Like 5800XM, 5530XM and the latest 5230 all use this system.

Classification

Currently, the UI (User Interface) platform of the Symbian system is divided into Series 60, Series 80, Series 90, UIQ, etc. based on different human-machine interfaces. In order to provide stronger support for the Symbian platform, Nokia established a new department, Nokia Mobile Software, in 2001 to develop mobile communications-related software. In order to give mobile phone manufacturers more choices to invest in the development of Symbian mobile phones, Nokia has developed three different user interfaces: Series 60/80/90. Series 60 is mainly for mobile phones with numeric keyboards, Series 80 is designed for complete keyboards, and Series 90 is designed for stylus mode. Another important platform is UIQ developed by UIQ Technology, which is 100% invested by Symbian.

UI platform developed by Nokia

Series 20/30 are mostly used by low-end mobile phones, Series 40 are mostly used by mid-range business mobile phones and support Java extensions, Series 60/80 /90 is designed for mid- to high-end smartphones and high-end business phones using the Symbian system.

Series 20: 84x48 pixels Series 30: 96x65 pixels, the model is generally 1 series, mobile phone models such as: 1100, 1108... Series 40: 96x68 or 128x128 pixels, mobile phone models such as: 1112, 1116, 1110i, 6230, 7210, 2610, 6020....Series 60: Supports multiple resolutions, models such as: 5310, 5320xm, 6122c, 6220c, N95, X6 and other newly launched X series smartphones. It is basically positioned as a one-hand control device. So far, it is divided into the first version, the second version and the third version, and the latest fifth version. The fifth version is a touch screen version, including Nokia E77, N97, 5800XM, 5802XM, 5530XM , Samsung i8910, the third version is also divided into pre-FP1 (MR), FP1, FP2, supports 176X208, 240x320, 352x416 resolution, five-directional keys, and two function keys. Use Symbian OS Preal platform. The menu inside is arranged in a nine-square or twelve-square grid. Supports MIDP JAVA and .SIS extension packages written in C++. A series of powerful mobile phones without sacrificing compact size. Representative machines include 6681/7610/N73/N80/N95. At the same time, this system and UI Style are also authorized to some other mobile phone manufacturers such as Siemens, Samsung, Panasonic, etc. Series 80: NOKIA calls this series of machines Communicator. There is only one series in terms of model, which is the 9 series. The Symbian OS Crystal platform is used. It represents NOKIA's strongest technology, and each generation is a collection of all NOKIA's most advanced technologies at that time. The biggest feature is that it looks like a pencil case (or remote control...). There is a standard mobile phone operation interface on the outside. When opened horizontally, there is a large 640X200 screen with four function keys, N shortcut keys and a complete QWERTY keyboard. The net weight is usually around 200 grams, but it has powerful functions. It can be said to be the best business phone. NOKIA's own senior executives basically use this thing. Typical representatives include 9110/9210/9300/9500. The last E90 Communicator incorporates NOKIA's strongest technology (not to mention transitional products such as 9000 and 9210C/9290, these are the only models in this series). Series 90: Using a large screen of 640X320, it is completely touch screen controlled except for a few function/direction keys. A typical representative is 7710. Because Seires 20/30 does not support extended functions, there is no corresponding UI Style document for them that is publicly available. The UI Style documents and SDK for Series 40 and Series 60/80/90 can be downloaded for free from Nokia’s Developers channel.

UI platform developed by UIQ

Symbian provides a flexible user interface (Use interface UI) to adapt to different user needs. There are currently many user interfaces based on Symbian, mainly Series 60/80/90 and UIQ. Among them, UIQ is the most powerful in terms of functionality, and it is also a system that is closer to the category of smartphones. We can all understand this UI as a Shell on Symbian, which "packages" the Symbian interface in different ways and adds some commonly used applications. In order to promote and improve UIQ, Symbian established UIQ Technology Company (UIQ Technolgy), a company designed to develop and promote UIQ. From the current point of view, it seems that UIQ is not as popular as Nokia's Series 60 system because there are relatively few mobile phone products based on the UIQ platform; but with the emergence of UIQ 3.0, this situation will change dramatically, and there will be more manufacturers to choose this year. Configure the UIQ platform for the product.

January 6, 2009 news, according to foreign media reports, the CEO of UIQ, a software company jointly established by Sony Ericsson and Motorola, said on Monday that the company had submitted a bankruptcy application to a Swedish district court. The software developer began laying off employees six months ago after shareholders decided to merge UIQ Software with the Symbian platform. Nokia completed its acquisition of Symbian last month and promised customers free access to the software. "In the current financial environment, there are no opportunities to create new businesses," UIQ Chief Executive Johan Sandberg told Reuters in an interview. The company has about 200 employees.

Series 60 interface introduction

As the user interface with the largest shipment volume among Symbian smartphones, Series 60 (referred to as "S60") has been sought after and loved by manufacturers and users. . The manufacturer has invested a lot of money in research and development of Series 60. Series 60 has had four versions since its birth, and there are multiple PARKs. The five versions of Series 60 support the following functions: Basic functions of the first version of Series 60: Personal information management; calendar, phone book, photo album, directory, file management application synchronized with PC; Connection: supports USB, Bluetooth, IrDA protocol.

Currently, there are many manufacturers supporting Symbian OS, and most people are optimistic about the development future of Symbian OS. Its good openness and easy development of third-party software can enable better and faster market capture. Basic functions of Series 60 fifth edition: The S60 platform skips the fourth edition and goes directly to the fifth edition. Some new features are added based on the third edition, such as supporting touch and handwriting operations on a 640*360 pixel large screen. Supports flash lite 3.0, supports displaying flash in web pages and watching online flash (FLV) videos on the network, virtual full keyboard, etc. Symbian^3 system: supports multi-touch, and has entertainment and office functions equivalent to Android systems

Edit this paragraph iOS

iOS is an operating system developed by Apple for the iPhone. It is mainly used for iPhone, iPod touch and iPad. Just like its Mac OS X-based operating system, it is also based on Darwin. Originally this system was called iPhone OS, until it was announced at the WWDC conference on June 7, 2010 that it would be renamed iOS. [2][3] The system architecture of iOS is divided into four levels: the Core OS layer, the Core Services layer, the Media layer, and the touch layer ( the Cocoa Touch layer). System operations occupy approximately 240MB of memory space.

Edit this paragraph Brew system

The closed system software developed by Qualcomm, the father of CDMA, is extremely difficult to install and is commonly found in CDMA mobile phones under 500 yuan. QQ BREW is the abbreviation of Binary Runtime Environment for Wireless. It is the basic platform for the development and operation of value-added services based on the CDMA network "Wireless Internet Launch Platform" launched by Qualcomm in 2001. Compared with Java, BREW is a lower-level technology.

BREW provides an efficient, low-cost, scalable and familiar Application Execution Environment (AEE) focused on developing applications that can be seamlessly embedded into any actual handheld device. Manufacturers and developers can expand the operating environment at any time to provide various additional performance modules required by applications, such as multimedia, multiple connection methods, location services, user interface, network and other functions included in the "Wireless Internet Launch Platform" kit. The functional environment provided by BREW is just like the operating system on a PC, and can be used by downloading specified types of applications or games through service providers. At the same time, through the BREW interface function, suppliers can provide a complete set of information, business, and entertainment functions. In future versions, BREW core classes will be able to provide services such as Bluetooth technology, Global Positioning System (GPS) and data-based telephony. OEMs can launch new devices more quickly because fewer in-house application development and integration tasks are required. Users can select and download wireless software that suits their personal preferences. In this way, users will drive the development of new wireless data applications and services market. BREW is mainly used in the field of mobile communications. BREW is similar to an open and free PC operating system. Other manufacturers can design various applications on this platform. As a mobile application platform, BREW can support dozens of data services such as high-speed Internet access, downloading games, and wireless shopping. Manufacturers use BREW to design an application software that can be used by all mobile phones equipped with Qualcomm chips. There will be no need to design separately for different mobile phone models on JAVA (another platform). In addition, BREW is also compatible with other languages, including JAVA and FLASH.

Edit this paragraph Windows Phone system

Windows Mobile system includes Pocket PC and Smartphone as well as Media Centers. Pocket PC is for wireless PDAs and Smartphone is for mobile phones. There are many from the IT industry Used by new mobile phone manufacturers, the growth rate is relatively fast. According to Microsoft's official statement: "Windows Mobile extends the familiar Windows experience to the mobile environment, so you can use it to get to work immediately." In fact, Windows Mobile is a major brand adjustment for Microsoft to enter the field of mobile devices, including Pocket PC , Smartphone and Media Centers three major platform systems, facing the personal mobile electronics consumer market. Since most models support color display, they consume a lot of power, and Windows CE itself consumes resources. In terms of function expansion, Microsoft prefers integrated use. Most of them have standard CF card slots. Users can add memory, install cameras, modems and other equipment according to their own needs. Windows Mobile, developed specifically for mobile phones by Microsoft, provides many functions, and the functions implemented on different platforms overlap with each other and have different focuses. All three platforms support data synchronization with desktop computers. The functions provided by Smartphone focus on contact. The main functions it supports are: phone calls, emails, contacts, and instant messages. The functions of PocketPC focus on personal affairs processing and simple entertainment. The main supported functions are: scheduling, mobile version of Office, and simple multimedia playback functions.

At 9:30 pm on October 11, 2010, Microsoft officially released the smartphone operating system Windows Phone 7, and also announced the first batch of 9 smartphones using Windows Phone 7. The earliest It will be available on October 21st. And use Windows Phone instead of the previous Windows Mobile.

Edit this paragraph Linux system

Linux system is an open source operating system, and there are many popular versions at present. But it has not yet received wider support. Linux has entered the mobile terminal operating system for more than a year, and its open source code advantages have attracted more and more terminal manufacturers and operators to pay attention to it, including well-known manufacturers such as Motorola and NTT DoCoMo.

Mobile phones based on Linux that have been developed include Motorola's A760, A768, CEC's e2800, Samsung's i519, etc. At the "LinuxWorld Expo/Tokyo 2004" held at the BIG SIGHT exhibition hall in Tokyo, Japan, in June 2004, NEC, a major Japanese mobile phone manufacturer, displayed its mobile phones using the Linux operating system. my country's Datang Telecom also announced in July that it will use Linux as its TD-SCDMA 3G mobile phone operating system. Linux is a latecomer compared to other operating systems, but Linux has two advantages that other operating systems cannot match. First, Linux has open source code, which can greatly reduce costs. Secondly, it not only meets the requirements of mobile phone manufacturers to develop their own Linux mobile operating systems based on actual conditions, but also attracts many software developers to develop content application software and enriches third-party applications. However, the Linux operating system has its inherent shortcomings: it is difficult to get started, there are few engineers familiar with its development environment, and the integrated development environment is poor; due to the non-disclosure of the source code of Microsoft's PC operating system, the connectivity between Linux-based products and PCs is poor. ; Although there are currently a large number of companies engaged in the development of Linux operating systems, there are very few companies with truly strong development capabilities. Moreover, these companies develop independently of each other, making it difficult to achieve greater technological breakthroughs. Although Linux has unique advantages in technology and market, it is currently unable to compete with Symbian. It is not easy to gain a foothold and grab market share in the increasingly competitive mobile phone market.

Edit this paragraph Palm OS

This is a 32-bit embedded operating system, mainly used on mobile terminals. This system was originally developed by the Palm Computing Department of 3Com Company. Palm Computing has now become an independent company. The combination of Palm OS and the synchronization software HotSync can synchronize information on mobile terminals and computers, extending the functions of desktop computers to mobile devices. The Palm OS operating system was developed by Palm itself and licensed to equipment manufacturers such as Handspring, Sony and Qualcomm. This operating system is more inclined to the operating system of PDA. Palm OS dominates the PDA market. Palm's product line itself includes smartphones, and it announced its merger with Handspring, the earliest smartphone developer, while making the software department independent.

Edit this paragraph Palm WebOS

Palm webOS is an embedded operating system that uses the Linux kernel as the main body and some proprietary software developed by Palm. It is mainly developed for Palm smartphones. The platform was announced to the public at the International Consumer Electronics Show in Las Vegas on January 8, 2009, and released on June 6, 2009. The platform is the de facto successor to PalmOS, webOS which focuses on online social networking and Web 2.0 integration. The first smartphone equipped with webOS system was Palm Pre, which was released on June 6, 2009. Note: Since Palm was acquired by HP, webOS is now owned by HP.

Palm Pixi, released on November 15, 2009. Later, an upgraded version of Palm Pixi Plus will be released on January 25, 2010, adding wifi functionality.

Edit this paragraph Android system

The latest android 3.0

This is an open source mobile operating system based on the Linux platform developed by Google. It includes the operating system, user interface, and applications—all the software a mobile phone needs to work—without any of the proprietary barriers that have previously hindered innovation in the mobile industry. Google developed Android in partnership with the Open Handset Alliance, which consists of more than 30 technology and wireless application leaders including China Mobile, Motorola, Qualcomm, HTC and T-Mobile. By forming in-depth partnerships with operators, device manufacturers, developers and other relevant parties, Google hopes to establish an open ecosystem within the mobile industry by establishing a standardized and open mobile phone software platform. . As an important part of Google's corporate strategy, Android will further promote the realization of the corporate goal of "providing information to everyone anytime, anywhere". We found that a large number of mobile phone users around the world have never used any Android-based phone. Google's goal is to make (mobile communications) independent of device or even platform. To this end, Android will complement, not replace, Google's long-standing mobile strategy: to develop mobile services that are both useful and engaging by partnering with phone manufacturers and mobile operators around the world. and promote these products.

Edit this paragraph BlackBerry OS

BlackBerry OS is a dedicated operating system for Research In Motion, developed by a third party. Third-party software developers can write software using APIs as well as proprietary BlackBerry APIs, but any application that needs to restrict the use of certain functions must be digitally signed so that users can contact RIM's Developer's account.

This signing of the program safeguards the author's application, but does not guarantee its quality or secure code.

How to tell whether a mobile phone has an operating system by editing this paragraph?

The mainstream smartphones include Symbian (S60 UIQ), LINUX WINDOWS, followed by PALM GOOGLE, Blackberry and non-smartphones developed by Apple. The operating system is not a real operating system. The S40 is a Nokia software platform. Nokia has not named its system. As for Samsung, LG and others, most of them use self-developed non-mainstream systems. Of course, domestically produced ones do not need to consider smart and non-smart phones. All support JAVA, and some domestically produced ones support JAVA. The difference between smart machines and non-smart machines mainly depends on whether they can be extended based on the functions of the system platform, not JAVA application platform. There is also support for multitasking.

Edit this paragraph's latest operating system introduction

MeeGo combines Nokia's Maemo and Intel's Moblin two Linux platforms, the new MeeGO was born. If Nokia's previous launch of Maemo was intended to improve the competitiveness of high-end smartphones and respond to the challenges of iPhone and Android, then the launch of MeeGo in conjunction with Intel fully demonstrates its ambitions in the mobile Internet field. This new operating system can be used not only on smartphones, but also on a series of terminal products such as portable Internet devices, laptops, TVs, and in-vehicle information systems. Since this system is not yet finished, it is difficult for us to evaluate it. However, as far as this move goes, it seems somewhat premature. Nokia just launched its first mobile phone N900 on the Maemo platform three months ago and promoted this system. Now Maemo will be replaced by MeeGO, which means that MeeGo is likely to be just one or two Nokia and Intel It is questionable whether a decision made within a month is well thought out. Moreover, in the field of software platforms, neither Intel's Moblin nor Nokia's Maemo can be considered successful. Both companies are industry leaders, but MeeGo cannot be called a perfect match. bada At a strategic level, Samsung's launch of bada operating system is of great significance to its future development. As the world's second largest mobile phone manufacturer, Samsung's previous performance in the smartphone market has been nothing but thunder. Although it has dabbled in almost all open operating systems, its terminal market share is negligible; in addition, in smartphones With this becoming an industry development trend, it will be difficult for Samsung to make a difference in the application market if it adopts a third-party operating system. And if you have your own operating system platform, all this may change. As far as the system itself is concerned, the debut of bada did not surprise us. In bada operating system, we have not seen revolutionary functions and user interfaces. Judging from feedback from domestic and foreign peers, the user experience of this system is somewhat disappointing. At present, bada does not have the strength to challenge operating systems such as iPhone and Android. Considering this aspect, it is difficult for bada to attract other mobile phone manufacturers. However, we cannot say that bada will not succeed. Samsung leads the industry in the non-smart touch screen mobile phone market, and many of its products are popular around the world. On this basis, Samsung may gradually use bada operating system products to replace non-intelligent products in the future, thereby gradually cultivating the ecological environment of this system; moreover, Samsung has also increased its investment in mobile phone applications, which will have Help improve the competitiveness of bada system
