Device Drivers
In several definitions that I've read it says that for Windows to perform I/O to a device (such as a sound card), it gives control to the driver for that device and the driver actually communicates with the device in its own special language. Now for the driver to do this it would need to know the I/O address and the memory address of this device (since that's the only way data is transferred). Is this the case, or does the driver communicate under Windows (like any other program), telling Windows "send this to sound card", and then Windows worrying about what I/O address to activate?

Unless you are using DOS, Windows is a Control Freak and doesnt let any device have control of the system.
