2. Introduction:- S ymbian OS is one of Nokia’s mobile operating system for mobile device and smartphones with associated libraries, user interface, frameworks and reference implementations of common tools, originally developed by Symbian Ltd.

3. HISTORY:- Psion founded by David Potter in 1980 launched the Psion Organizer, the world’s first volume-produced handheld computer in 1984. 1997: Psion’s EPOC OS Launched(2 MB memory) 1998: Symbian consortium and Symbian OS Independent of Psion Ericsson, Nokia, Motorola, Psion(founders) Panasonic, Sony Ericsson, Siemens, Samsung(shareholders) 2000: First Symbian OS phone Ericsson R380

4. Market share:- Symbian OS runs on ~75% of all mobiles. Nokia expects the mobile market to exceed 250 million units in 2008 82.8 million cumulative Symbian OS phone shipments since the formation of Symbian (as of Q2 2006). Symbian C++ gives Maximum flexibility Speed

5. Symbian Device platforms Same Basis, different feel and look due to different at UI layer: S 60: Smartphone with numeric keypad, “phone centric S 80: Organizers with full keyboard, “information centric” e.g. Nokia 9300 UIQ: mobile phone with pen input, “information centric” e.g. Sony Ericssion P910

6. advantages Greater range of application. High quality games. Better inbuilt web browser. Connectivity is not more easier and faster. Real Player, Smart movie player etc. sort of application are not available with java phones. You can install software and application of any type.

7. Supported devices..

8. Shares of symbian os in devices..

9. architecture

10. UI Framework… Frameworks and libraries for constructing a UI Includes the basic class hierarchies for UI controls Concrete widget classes used by UI components Other frameworks and utlities Topmost layer of Symbian OS, foundation for variant UI

11. Application services.. UI independent support for application Including basic application frameworks/services Application class(“technology specification”) logic Support for specific application Also some applocation engines used and extended by licensees Generic Application class specific- Messaging, browsing Application specific – Word, Sheet Engines vs services - evolving

12. Os services.. Extends the “base” into a fully functional OS providing services across a fully range of technologies, e.g. graphics, communications, multimedia, etc. Organised by technology domain Generic OS Services “Middleware” layer of Symbian OS, full range of servers, framework, and libraries which extend the base system into a complete OS Connectivity Services Multimedia & Graphics Services

13. Base services.. It includes the file Server and User Library Plug-In Framework which manages all plug-in Central Repository, DBMS Cryptographic services Services for a functional port Lowest level of user-side services, extends the OS kernel into a useable(but minimal) system

14. Kernel services & hardware interface.. Bootstraps the physical or emulated device Provides physical and logical device drivers and other hardware abstraction Create and manages the fundamental OS kernel abstractions Processes, memory management, scheduling Kernel layer, contains the OS kernel itself, device drivers, and similar low-level components

15. The Fall Of The Symbian OS Poor internet performance Failure to gain advantage from being open-source   The unsatisfactory app-availability Developers started to hate Symbian The boring user-interface (UI ) Symbian did’t target the smartphone market. The unmanageable network of Symbian partners
