3. 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.

4. 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.

5. How does Symbian OS work?
Symbian OS provides the underlying routines and services for application software. Ex. an software that interacts with a user through a mobile phone screen, downloads 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

6. 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.

7. 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.

The kernel manages the machines hardware resources such as system RAM and hardware devices.

9. 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

13. 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.

14. 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

15. 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

16. 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

17. 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.
