    Q&A
  • 10. Communication is what?
  • 11. Talk about “More”
    • Object orientation
    • 12. Microkernel design
    • 13. Client/Server models
  • Infrastructure
  • 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.
  • 17. Modularity
