The primary function of peripheral device drivers is to serve as an intermediary between peripherals and applications. Device drivers facilitate communication between the operating system and hardware devices, allowing applications to send and receive data from peripherals like printers, scanners, or external storage devices. Without these drivers, the operating system would not be able to understand how to operate the hardware effectively, nor would it be able to exchange information appropriately.

While enhancing graphics performance is an important role for some specific drivers, it is not the primary function of all device drivers. Similarly, providing system security and managing power consumption are critical functions within a computer system but are managed by different components or software processes, not directly by peripheral device drivers. Thus, the essential role of device drivers is centered around ensuring seamless communication and operation between the operating system and peripheral devices.
