But this hardware device needs a special control program (that is, driver) to play a role.
Windows system does not have this driver, so you need to install it yourself.
Driver refers to the device driver, which is a special program that enables the computer to communicate with the device. Equivalent to the interface of hardware. Only through this interface can the operating system control the work of hardware devices. If the driver of the device is not installed correctly, it will not work properly.
Device driver is used to tell the operating system the function of the hardware itself, and complete the translation between the electronic signal of the hardware device and the high-level programming language of the operating system and software. When the operating system needs to use some hardware, such as letting the sound card play music, it will first send corresponding instructions to the sound card driver, and the sound card driver will immediately translate them into electronic signal commands that the sound card can understand, so that the sound card can play music.
Drivers can generally be obtained in three ways. First, the purchased hardware comes with its own driver. Second, Windows system comes with a large number of drivers (common hardware devices); Third, download the driver from the Internet.
