What are Windows Device Drivers

Device drivers are little files an operating system uses to communicate with different hardware devices attached to your pc. As opposed to talking directly with the hardware, then the machine sends messages via a motorist, which calls the purposes for each device as it’s required. A device driver serves its function with little to no input from the end user. By way of instance, after a driver is set up, it’s probably you will not ever need to interact with this.
