A driver is a configuration file that is written by the hardware manufacturer based on the operating system and is a small piece of code added to the operating system that contains information about the hardware device. The driver is an integral component when new hardware is installed. You can say that without a driver, the hardware in your computer will not work. With this information in the driver, the computer can communicate with the device.

Different operating systems, hardware drivers are different, the hardware manufacturers to ensure the compatibility of hardware and enhance the functionality of the hardware will continue to upgrade the driver. For example, the Nvidia graphics chip company upgrades the graphics driver 2-3 times a month on average.
