SYMBIAN MOBILE OPERATING SYSTEM.pptx

  1. 1. Submitted By: Suraj Kumar MCA-3 2111935 Submitted To: Mrs. Jaspreet kaur
  2. 2.  Symbian 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. 3.  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. 4.  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. 5. 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. 6.  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. 7.  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
  8. 8.  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
  9. 9. o Extends the “base” into a fully functional OS providing services across a fully range of technologies, e.g. graphics, communications, multimedia, etc. o Organised by technology domain “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
  10. 10.  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
  11. 11.  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
  12. 12.  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
