FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -An Operating System is a program that acts as an intermediary or interface between a user of a computer and the computer hardware. It is the most important type of system software in computer systems. Without an operating system the user cannot run application programs on the computer system.

Detailed explanation-3: -The Device Controller works like an interface between a device and a device driver. I/O units (Keyboard, mouse, printer, etc.) typically consist of a mechanical component and an electronic component where electronic component is called the device controller.

Detailed explanation-4: -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.

Detailed explanation-5: -Device Driver in computing refers to a special kind of software program or a specific type of software application that controls a specific hardware device that enables different hardware devices to communicate with the computer’s Operating System.
