Framework Applications
System layer
CORE
Symbian OS
UI Platforms

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

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

16. • Development requirements :
1.S 60
2.UIQ
3.MOAP
and the IDE tool of your choice.

17. • An IDE is a software application that allows the computer
programmer to develop a software for a certain platform.
