Computer driver refers to the device driver, which is a special program that enables computers and devices to communicate with each other. It is equivalent to the interface of hardware. Only through this interface can the operating system control the work of hardware equipment. If the driver of a device is not installed correctly, it will not work normally. Therefore, drivers are compared to "the soul of hardware", "the master of hardware", and "the bridge between hardware and system".
The driver is essentially a software code. Its main function is to complete the function of data transmission between the computer system and the hardware equipment. Only with the help of the driver can the two communicate and complete specific functions. If a hardware device does not have a driver, only the operating system cannot play its unique functions, that is, the driver is a medium between the operating system and the hardware to realize two-way communication, that is, the functions of the hardware device itself are communicated to the operating system, and the standard instructions of the operating system are also communicated to the hardware device, So as to realize the seamless connection between the two. （DianNaoQuDongGanMaYongDe）
