Devesh Kumar presented on the Symbian mobile operating system. Symbian OS was developed by Symbian for smartphones and was widely used by Nokia. It discussed the history and founders of Symbian. Key features of Symbian OS include its thread-based processing, memory management using virtual paging, and client-server architecture. Strengths include robust memory management, but weaknesses include a lack of virtual memory. Symbian also had a microkernel architecture and included various interfaces like Series 80. The presentation provided an overview of developing on Symbian OS and concluded by comparing it to Android.

Symbian OS is one of Nokia's mobile operating system for mobile
devices and smartphones, with associated libraries, user
interface, frameworks and reference implementations of common
tools, originally developed by Symbian Ltd.

 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..
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
How Symbian OS Addresses Memory
1. Symbian OS is a 32-bit operating system, addresses can
range up to 4 GB
2. Symbian OS divides memory into virtual pages and physical
frames
3. Symbian OS adopts a two-level page table strategy

STRENGTH
•MEMORY MANAGEMENT
•EXECUTION IN ONE PLACE
WEAKNESS
•NO VITUAL MEMORY

SYMBIAN ACHITECTURE
• 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.

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.

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.
