Psion founded by David Potter inn 1980 launched the Psion
Organizer, the world's first volume-produced handheld computer in
1984.
In June 1998 - Symbian is established as a private independent
company and is owned by Ericsson, Nokia, Motorola and Psion.
From this point onwards has EPOC OS been called Symbian OS.
In February 2004 - Symbian OS v8.0 is announced.
In February 2005 - Symbian OS v9 is announced.
In May 2006 - 100th commercial phone model ships

HISTORY Contd..
MR.DEVESH KUMAR(Roll#CSE201210120)
In 2008, the former Symbian Software Limited was acquired by Nokia
and a new independent non-profit organization called the Symbian
Foundation was established.
The platform has been designated as the successor to Symbian OS,
following the official launch of the Symbian Foundation in April 2009.
The Symbian Platform was officially made available as open source
code in February 2010.

MEMORY MANAGEMENT
MR.DEVESH KUMAR(Roll#CSE201210120)
How Symbian OS Addresses Memory1. Symbian OS is a 32-bit operating system, addresses can
range up to 4 GB2. Symbian OS divides memory into virtual pages and physical
frames3. Symbian OS adopts a two-level page table strategy

SYMBIAN ACHITECTURE
MR.DEVESH KUMAR(Roll#CSE201210120)
• 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.

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.

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.
