10. Communication is what?

12. Microkernel design

14. The Physical Device Symbian OS has no control over hardware That is API design. We will treat as an abstract.  Can handle wide variety of devices now and also future.

15. The Device Driver Layer Logical Device Driver( LDD): Layer interfaces with the protocol implementation layer and Symbian OS policies. Physical Device Driver( PDD): Layer interfaces directly with the physical device through a specific hardware port.

16. The protocol Implementation Layer Four types of modules: CSY Modules: Communicate directly with the hardware through PDD portion of device driver. Implementing the various low-level aspects of protocol. TSY Modules: Implement the telephony fuctionality. PRT Modules: Central modules used for protocol implementation. MTMs: Handle all type of messaging.
