INDEX Introduction History How symbian works System structure Some special features Various application of symbian os Advantage Limitations conclusion

INTRODUCTION Symbian os is an operating system, designed for mobile devices, with associated libraries, user interface frameworks and reference implementations of common tools, developed by symbian ltd. The native language of the symbian OS is C++, although it is not a standard implementation. There are multiple platforms based upon symbian OS provide various application.

History of symbian os Symbian established as a private independent company in june 1998, owned by ericsson, nokia, motorola and Psion Nokia 6600, the first phone to utilize symbian OS v7.0s produced.

How does Symbian OS work? Symbian OS provides the underlying routines and services for application software. Ex. an email software that interacts with a user through a mobile phone screen, downloads email messages to the phone's inbox over a mobile network access. The os is developoed with this features: to provide power, memory and input & output resource management specifically required in mobile devices to provide tools for developing mobile software for business, media and other applications to ensure the wide availability of applications and accessories for different user requirements

System structure Hardware resources CPU:- symbian os is designed for 32 bit CPUs running at lower speed compared with desktop or PCs. ROM:- the system ROM is mapped as the z: drive. so programs are being executed in place rather then being loaded in to RAM. System RAM:- the system RAM is used for two purpose: RAM for use by active programs and the system kernel, and RAM used as ‘disk’ space accessed as the c: drive. I/O device: A screen with ‘digitizer’ for pen input, A keyboard An infrared port Bluetooth for wireless transfer of data between symbian os phones and others such as palm PDAs or nokia communications.

Software basics A server is program without a user interface. A server manages one or more resources. It provides an APIs so that client can access to its services. An engine is the part of an application that manipulates data, rather than the part that interacts directly with the user. An application is a program with a user interface. Each applications runs in separate process with its own virtual address space.

Software development kits A software development kit (SDK) for symbian OS support development in both C++ and Java. They provide: full system documentation for APIs and tools PC-based emulation of Symbian OS phones It supports DLL that system loads a DLL in to context of an exiting process SDKs are built based on a particular UI platform that supports browsing, telephony, multimedia and contact/calendar management. It contains shared library DLL and polymorphic DLL

Latest version of symbian os v9.5 Symbian OS v9.5, the latest evolution of Symbian OS, delivers over 70 new features for high-performance, more powerful smart phones at mass market costs. Higher performance at lower hardware cost Designed for richer user experiences Faster time-to-market

Different version of symbian based mobile series Definition of "S60" Formerly known as Series 60, S60 is primarily used by Nokia on its own handsets, but has been licensed by other manufacturers such as Samsung, Siemens, and LG.  Definition of "S80" S80 is the software platform that Nokia runs on top of the Symbian OS for its 9000 series of communicator devices.  Definition of "S90" S90 is the software platform that Nokia runs Symbian OS in its 77xx series of touchscreen enabled multimedia devices.

Various application of symbian os Networking & Communications Multimedia & Graphic Kernel & Hardware Services Telephony Symbian OS is the market leading operating system for advanced data-enabled mobile phones. It is designed for the specific requirements of advanced 3G mobile phones and beyond All smart phones that are currently used for voice, video, recording, web based use, mailing are operated by symbian Game development

Advantage Wide selection of applications available for a range of smart phones Implements industry standard protocols, interfaces and management services for IT system integration Application development using industry standard Java and C++ languages Extensive connectivity options - including GSM, GPRS, CDMA, WCDMA, WiFi and Bluetooth

Limitations Environment monopoly Hacking Symbian S60 version devices can be hacked OS 9.X that allow hacker to install "unsigned" files and allowing access to previously locked system files. This allows changing of how the operating system works, allowing hidden applications etc. to be viewable. Environment monopoly Symbian requires the use of special techniques such as descriptors and the cleanup stack. This can make even relatively simple programs harder to implement than in other environments. Not platform independence

conclusion So, Symbian OS is the advanced, open operating system licensed by the world’s leading mobile phone manufacturers. It is designed for the specific requirements of advanced 2.5G and 3G mobile phones. It combines the power of an integrated applications environment with mobile telephony, bringing advanced data services to the mass market. So we can say that next generation will be totally of symbian os devices. A truly scalable operating system for the global market.
