Answer / Manish Singh
Virtual device drivers are used to abstract the interaction between software and hardware, providing a layer of abstraction over the physical device driver. This abstraction enables multiple applications or operating systems to share the same hardware resources by simulating the devices virtually. Virtual device drivers also help in testing, emulation, and debugging as they allow for easier isolation and manipulation of the hardware.
