CONTENTS

Symbian is a mobile operating system (OS) and

computing platform designed for Smartphone's and

currently maintained by Accenture.

INTRODUCTION

Symbian was formed in 1998, Psion contributed EPOC into the group.

EPOC was renamed Symbian OS and has been progressively updated, incorporating both voice and data telephony technologies of ever greater sophistication with every product release.

HISTORY

Symbian OS 6.0 and 6.1 Symbian OS 7.0 and 7.0s (including MMF) Symbian OS 8.0 and 8.1 Symbian OS 9.0, 9.1, 9.2, 9.3, 9.4 Symbian^2 Symbian^3 (Symbian OS 9.5) and Symbian Anna Nokia Belle (Symbian OS 10.1)

VERSIONS

FEATURES

ARCHITECTURE

The Symbian kernel (EKA2) supports sufficiently fast real-time response.

 The real-time kernel has a microkernel architecture containing only the minimum, most basic primitives and functionality, for maximum robustness, availability and responsiveness

KERNEL AND HARDWARE INTEGRATION

 Includes the File Server and User Library

A Plug-In Framework which manages all plug-ins,

Store, Central Repository, DBMS and cryptographic

service

It also includes the Text Window Server and the Text

BASE SERVICES

Cellular Baseband Services

Communications Framework

Device Services

Generic OS Services

OS SERVICES

Messaging Browsing Data synchronization  Java ME providing another set of APIs on top of

most of the OS and multimedia

APPLICATION SERVICES

S60, UIQ and MOAP — were contributed to

Symbian in 2009.

Symbian also contains graphics, text layout and

font rendering libraries.

USER INTERFACE SERVICES

Stack and Heap Leaves Cleanup Stack Two Phase Construction Memory Leaks

MEMORY MANAGEMENT

Symbian 9.1 introduced capabilities and a Platform Security framework. To access certain APIs, developers have to sign their application with a digital signature.

The Symbian platform attempts to ensure the integrity of data even in the presence of unreliable communication and a shortage of resources, such as memory, power, and storage.

PLATFORM SECURITY

DEVICE SECURITY

Device protection: Protection of the Symbian platform-based device against a physical attack is controlled by the device lock feature, which is not necessarily often used.

Device Authentication: When powering on the device, the user is authenticated in the operating system

level with standard device authentication methods, such as a PIN code and security code requests.

DEVICE SECURITY..(CONT)

Robust and Multitasking Natively IP-based, with fully integrated

communications and messaging. Enables a large community of developers The open platform allows the installation of third

party software to further enhance the platform.
