A driver is small software that tells the computer operating system how to communicate with the hardware components and other connected devices. A Multifunction Enumerator or device contains more than one function, for example, it can be a driver for combined functions, and its functionality is similar to multifunction modem and network cards. To function effectively, the functions contained in the multifunction device should be independent from each other, start-order dependencies must not be present, and the resource requirements for one function must not be expressed in terms of the resources of another function. By default, mf.sys device driver is installed in earlier version of Windows but is not installed in Windows Vista.
