Concept:A device driver is a special program that helps the operating system control and manage hardware.
Explanation:The operating system cannot communicate with hardware devices directly because each device has its own design.
A device driver acts as a bridge between the operating system and the hardware.
When an application needs to print, the operating system uses the printer driver to send the correct signals to the printer.
Without the correct driver, the operating system may not recognise the device or the device may not function properly.
Drivers are available for keyboards, mice, monitors, printers, sound cards, and many other components.
Therefore, the primary purpose of device drivers is to manage and coordinate hardware devices.
