What is VXD?
| Virtual Device Drivers |
|
A Windows program which can run in the background. A scanner implemented as a VxD has all the advantages of a DOS TSR, but can have additional advantages: for instance, a good VxD will scan continuously. VXD stands for virtual device drivers. The abbreviation VXD is commonly used in the Windows 9x environment because the filename ends in the .vxd extension. In older versions of Windows, drivers often have a.DRV extension. In Windows NT virtual device drivers are simply referred to as VDDs. (Windows NT does not support Windows 9x VXDs.) A driver is a program that controls a device (hardware). The driver acts like a translator between the device and programs that use the devices. All devices has its own set of specialized commands, or set of routines, that only its driver knows. All devices, printers, keyboards, modems, etc., have a driver program to run with the operating system. Many drivers, such as the keyboard driver, come with the operating system, while other drivers need to be manually loaded into the operating system to connect the device to the computer. |
