Symbian Run Modes

Symbian runs in 2 Modes.

1. User mode – kernel services can only be accessed through the EUSER.DLL. The lack of a proper kernel port does not stop the development of user-side components because the platform provides a complete Kernel Port for the PC environment under the Windows Operating System. This is called the emulator.

2 Kernel mode – EUSER.DLL is an interface between common code and hardware-specific code. In the other words, kernel mode means that the software is run on the target hardware.
