Meaning of DRIVER in English
This term usually refers to the person behind the wheel of a moving car. In the computer world, however, a driver is a small file that helps the computer communicates with a certain hardware device. It contains information needed to recognize and control the device which the computer does not already have. In Windows-based PCs, a driver is often packaged as a dynamic link library (DLL) file; in Macs, most hardware devices don't need drivers, but the ones that do usually come with a software driver in the form of a System Extension.
