Detailed explanation-1: -A device driver may also be called a software driver. Drivers facilitate communication between an operating system and a peripheral hardware device.
Detailed explanation-2: -A device driver is a special kind of software program that controls a specific hardware device attached to a computer. Device drivers are essential for a computer to work properly.
Detailed explanation-3: -Device drivers operate inside the OS kernel layer. They work in a highly privileged environment because they need low-level access to hardware operations to function. They enable the computer’s operating system (OS) to interface with the hardware for which they were developed.
Detailed explanation-4: -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 (drives it).
Detailed explanation-5: -A device driver communicates between the OS and the computer’s physical devices.
