virtual device driver

In certain Microsoft operating systems, a virtual device driver is a program that handles software interrupts from the operating system (rather than hardware interrupts) for each of the computer's main hardware devices, including the hard disk drive controller, keyboard, and serial and parallel ports. A virtual device driver is used to maintain the status of a hardware device that has changeable settings.

A virtual device driver usually has a file name suffix of VXD.
