SYMBIAN ACHITECTURE


• Symbian has a microkernel architecture, which means that the minimum necessary is within the kernel to maximise robustness, availability and responsiveness.

• Symbian is designed to compatibility with other devices, especially removable media file systems.

• There is also a large volume of User Interface (UI) Code. • Symbian includes a reference user-interface called

"TechView". • It is very similar to the user interface from the Psion Series 5

personal organiser and is not used for any production phone user interface.

PLATFORM SECURITY



Example of Applications where the Symbian OS is being used• Nokia Series 80 interface

• UIQ interface(Used for PDAs such as Sony Ericsson P800 )

• Nokia S60 interface• Nokia S40 interface



DEVELOPING SYMBIAN OS• As of 2010, the SDK for Symbian is standard C++, using Qt. It

can be used with either Qt creator, or Carbide (the older IDE

previously used for Symbian development).

• A phone simulator allows testing of Qt apps.

• It is also possible to develop using Symbian C++, although it is

not a standard implementation.

• Prior to the release of the Qt SDK, this was the standard

development environment.



ADVANTAGES• Greater range of applications.

• High quality games.

• Better inbuilt wap browser.

• Connectivity is lot more easier and faster.

• Real Player, Smart movie player etc. sort of application are not

available with java phones.

• You can install software and applications of any type

• You can download big files through your phone easily with 3G

around.

DISADVANTAGE

• The OS is not available for PCs .

• The Symbian OS can be easily affected by a Virus.



Communication in Symbian OS

• Figure Communication in Symbian OS has block oriented structure.



CONCLUSION…..In the small and rapidly growing world the need of mobiles and its applications are obvious. To meet the users embedded OS are playing the vital. To speak in a sentence about Android and Symbian, Android is much advanced and provides more value to the end users. Symbian needs updates its features.
