In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer.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 of the hardware being used.

A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

A device driver is a small piece of software that tells the operating system and other software how to communicate with a piece of hardware.

For example, printer drivers tell the operating system, and by extension whatever program you have the thing you want to print open in, exactly how to print information on the page

Sound card drivers are necessary so your operating system knows exactly how to translate the 1’s and 0’s that comprise that MP3 file into audio signals that the sound card can output to your headphones or speakers.

Keep reading for more on why drivers are important, including some more examples, as well as information on how to keep your drivers updated and what to do if they’re not working properly.
