What should I do if my boxing gloves are a little moldy?

Symbian is a joint venture company jointly established by several large mobile communication equipment manufacturers such as Motorola, Siemens, and Nokia to specialize in the development of mobile phone operating systems. The predecessor of Symbian operating system is EPOC, and EPOC is derived from the first letter of Electronic Piece of Cheese. Its original meaning is "using electronic products can be as easy as eating cheese". This is what it insists on when designing. idea.

The Symbian operating system has powerful applications and communication capabilities on smart mobile terminals, thanks to its very sound core - a powerful object-oriented system, enterprise standard communication transmission protocols and The perfect sun java language. Symbian believes that in addition to providing voice communication functions, wireless communication devices should also have other communication methods, such as stylus, keyboard, etc. In terms of hardware design, it can provide many different styles of appearance, such as using real or virtual keyboards. In terms of software functions, it can accommodate many functions, including sharing information with others, browsing the web, transmitting, receiving e-mails, faxes, and Personal life schedule management, etc. In addition, the Symbian operating system has reserved a variety of interfaces for manufacturers in terms of scalability, and the EPOC operating system can also be subdivided into three types: Pearl/Quartz/Crystal, which correspond to ordinary mobile phones, smart phones, and Hand Held PCs respectively. application.

Symbian is a real-time, multi-tasking pure 32-bit operating system with low power consumption and small memory usage. It is very suitable for use on mobile devices such as mobile phones. After continuous improvement, it can support GPRS, Bluetooth, etc. Bud, 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.

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 an Ericsson 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 been developed to 7.0. It is specially developed for 3G networks and can be said to represent the most powerful mobile phone operating system today. In addition, Symbian has supported external storage devices, such as MMC, CF cards, etc., 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.

Symbian is divided by version. Following the launch of a new mobile operating system software OSv9.0 by Symbian in February 2005, so far there have been 6.0, 6.1, 7.0, 7.0s, 8.0, 9.0 several versions. In March 1999, Symbian launched the Symbian 5.0 operating system. Its main kernel integrates network, wireless text, email, business card book and personal information assistant. It also has a browser that supports standard network pages and supports Java language. , allowing Symbian to run small applications.

However, this version uses very few models and is basically not much different from EPOC.

Symbian 6.0 adds support for GPRS, WAP1.2 browser and Bluetooth technology on the basis of 5.0. Users can run third-party programs developed based on C++ and J2ME. Compared with Symbian 6.0, Symbian 6.1 mainly adds support for USB. The main features of Symbian 6.0 are: supports voice calls and data communications, supports Bluetooth and WAP, is equipped with security functions (SSL, HTTPS, WTLS), uses 16bit Unicode, supports multi-language display, uses "PersonalJava 3.0" and "JavaPhone 1.0" .

Symbian 7.0 supports multi-mode and 3G mobile phones (special area), allowing manufacturers to launch Symbian OS mobile phones around the world that can run on all networks without making major changes to the code. In this case, many existing software applications can be reused. 7.0 includes some new communications, messaging, networking, and application development technologies, as well as improvements to some security and authentication-related features. Other features of Symbian OS 7.0 include: support for flexible user interfaces such as Nokia's Series 60; support for several audio/image formats and many APIs for game developers; full encryption and authentication management, based on secure communication protocols (including HTTPS , WTLS and SSL) and certified application installation; and Over-the-air (OTA) SyncML synchronization support.

In February 2004, when Symbian authorized LG and other companies, it released the Symbian8.0 version. This version improves real-time system performance and improves compatibility with original operating systems. In addition, Symbian OS 8.0's software tools improve remote access control system functionality and use adjustment devices to eliminate interference for mobile phone users when using value-added services. This system contains absolutely modern multimedia and Java devices, supporting multiple standards, including JSR118, CLDC1.1 (JSR139), MobileMedia (JSR135), 3D image data (JSR184), JTWI 1.0 c (JSR185). Finally, the new version of OS also supports SDIO.

In February 2005, Symbian, a famous British mobile phone software manufacturer, launched a new mobile operating system software OSv9.0, which supports higher-pixel digital cameras and three-dimensional game animations. The operating system software has high requirements on the operating environment. It currently runs on a fast processor chip provided by British chip developer ARM, and requires the support of related designs and other tools to help mobile phone manufacturers save time and money when developing other versions. Reduce costs. The software can process 2-megapixel digital pictures and even send stereo music to wireless headphones. Even better, it can export MP3 files from a PC without the need for synchronization software.

Series60 is the most widely used system version in smartphones. The Series60 system is also divided into three versions: 6.0 OS, 7.0 OS and 8.0 OS. The most intuitive factor that distinguishes Series60 is the resolution of the screen. The resolution supported by Series60 is 176*208 pixels, but in the future, S60 will also support 240*320 pixels, 352*416 pixels, etc. S60 is the interface with the most third-party software or games.

The easiest way to identify the Series80 interface is to see if the phone supports a full keyboard. For example, Nokia's high-end series 9210, 9300 and even 9500 all use full keyboards. The easiest way to identify Series90 is that it uses a touch screen with a resolution of 640*320 pixels. Series90 should be the strongest platform for mobile games and entertainment, but because there are too few mobile phone models using the Series90 interface and little third-party software support, the S60 is still the first choice for players.

S40 or S60 refers to the upper platform of Nokia mobile phones.

The S60 are all smartphones, and the underlying operating system used is Symbian. Nokia's 128*128 screens are all S40 1.0. And 128*160 is S40 2.0.

In addition, among the S40, 3100 supports java MIDP 1.0, so it supports a maximum of 64KB of java; 6230 supports java MIDP 2.0, so it supports a maximum of 128KB of java 40 and 60, including 90 and the previous 30. For an operating system different from Nokia, 40 is a mobile operating system developed by Nokia. It supports the development of kjava for mid-to-low-end customers. Its processor efficiency is not high, the memory is low, and the screen size is 128*128.

S60 is based on the Symbian operating system, which is the previous epoc. Its processor is arm9, which has high processing efficiency, large memory, and a screen size of 208*176. It also supports the development of kjava and C++ 90 , is a handheld device, also runs on Symbian operating system but has powerful functions, equivalent to a PDA.

In fact, technically speaking, the difference between S40 and S60 is in the system platform, just like WIN98 and WIN2000. However, mobile phones are not like PCs. The screen size is indeed a barrier, so it is not easy for the platform to move downwards. Compatible, but some games also have different versions.

Of course, the difference between S40 and S60 is not only in screen, but also in performance. Generally speaking, the quality of games developed by S60 is much higher than that of S40, but unfortunately, S60 It is much more expensive than the S40 machine.

On many websites, some people who do not know much about Symbian think that Series 60 and Series 80 are different Symbian operating system versions. As a result, more confusing titles emerged. For example: "Series 60 operating system" and "Symbian 80 operating system" jokes.

In fact, Symbian operating system is a mobile operating system developed by Symbian Company. It is an operating system independent of mobile phone hardware, and it is an open platform. This is a bit like Linux. There are common user interfaces on the market such as Red Hat, but they are all developed under the Linux system, but the interfaces are somewhat different.

Therefore, many mobile phone manufacturers made some interface modifications on the mobile phones produced by their own companies, so names such as S60 and S80 appeared. But they are not operating systems, but user interface platforms developed based on operating systems.

Currently, Series 60 has two main versions: 2nd Edition and 3rd Edition

Series 60 Platform 2nd Edition

Series 60 Platform 2nd 2nd Edition was originally released in 2003, and the first terminal to be implemented was the Nokia 6600 mobile phone.
