8. Architectural Overview
1. Core : Symbian OS core is common to all
devices i.e. kernel, file server, memory
management & device drivers.
2. System layer : It provides communication &
computing services such as TCP/IP, SMS &
database management.
3. Application Engines : It’s above the system layer,
enabling the software developers to create user
interface to data.

9. 4. User Interface Software : It can be
made or licensed by
manufacturers.
5. Applications : are slotted aboved
the user interface & pre-loaded in
the Symbian OS mobile phone.

10. Software Devlopment

11. What is IDE ?

12. Tools to for the software development
Tool name Description
GCC for Symbian Compile Symbian C++ Applications.
Symbian Certificate manager Allows you to manage your device’s
certificates.
Symbian DevCert Request Enables you to obtain Symbian Developer
Certificate.
Symbian MakeSIS It converts your C++ applications in .SIS
packages(formats).
Symbian UnSIS Extracts the .SIS packages.

13.  Symbian OS offers a choice of programming
