Device Driver is a special program that can make computers communicate with devices. It can be said that it is equivalent to the interface of hardware. Only through this interface can the operating system control the work of hardware devices. If the driver of a device is not installed correctly, it will not work normally. It is for this reason that drivers play an important role in the system. Generally, after the operating system is installed, the first thing is to install drivers for hardware devices. However, in most cases, we don't need to install drivers for all hardware devices, such as hard disks, monitors and CD-ROMs, but drivers for graphics cards, sound cards, scanners, cameras and Modem. In addition, different versions of the operating system support different hardware devices. Generally, the higher the version, the more hardware devices are supported. For example, the author uses Windows XP, and there is no need to install a driver after installing the system.
