COMPUTER FUNDAMENTALS

Detailed explanation-1: -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-2: -A device driver is a piece of software that allows your computer’s operating system to communicate with a hardware device the driver is written for. Generally, a driver communicates with the device through the computer bus, which connects the device with the computer.

Detailed explanation-3: -Generally a driver communicates with the device through the computer bus which is used to connect the device with the computer. Device drivers works within the kernel layer of the operating system. Kernel is the part of the operating system that directly interacts with the physical structure of the system.

Detailed explanation-4: -Purpose of device drivers Device drivers are necessary to permit a computer to interface and interact with specific devices. They define the messages and mechanisms whereby the computer–the OS and applications–can access the device or make requests for the device to fulfill.
