Difference between User Mode and Kernel Mode

[senthilnathan.rajesh]

Can any body explain me the basic difference between user mode and kernel mode application in windows

Thanks

kernel mode is the supervisor mode where everything is allowed. whenever there is a system call execution changes frm the user mode to the kernel mode..kernel mode executing a system call is on behalf of the calling process....

in user mode direct access to the hardware and the memory is prohibted in order too avoid the malicious user ...

and thatz why we are using the kernel file with the windows xp to enable the C and other languages from accessing the hardware

You will specify the kernel mode when your code is to be executed in the kernel mode.
