A device driver of output device

Explanation

A device driver is a specialized software program that acts as a translator between a computer's operating system and its hardware peripherals. For an output device (such as a monitor, printer, or speaker), the driver takes the digital data processed by the computer and translates it into specific instructions that the hardware can use to generate an output. This process effectively interprets computer output into a form that is understandable or perceivable by the user (e.g., text on a screen or a printed document). In contrast, an input device driver (like that for a keyboard) performs the opposite task by converting user-provided input into a computer-usable binary form.
