Meaning – In the context of computing, a device driver is a software that controls how a peripheral device works, when it is connected to a computer system. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.
When a new peripheral device is inserted, the computer first checks to see the class of the device, and if sufficient information is not available, it checks to see if a suitable driver has been bundled. This driver acts as a conduit between the computer and the peripheral device.
Sometimes, if the driver has been subject to an update, the company communicates the same to all users, so that they may download the updated driver. This ensures that the peripheral device keeps working properly with your computer.
Example of usage – “The device driver for the USB device was given an update, which the gamer had to download and install, in order to keep the device working seamlessly with the computer.”
