The correct answer is option 'C' - Device Drivers.


The program that provides a software interface to hardware devices is called a device driver. Device drivers are essential software components that allow the operating system to communicate and interact with hardware devices.

1. System Software:
System software refers to the software that manages and controls the operation of computer hardware and provides a platform for running application software. It includes the operating system, utility programs, and device drivers. While system software plays a crucial role in managing hardware resources, it does not specifically provide a software interface to hardware devices.

2. Application Software:
Application software refers to the software designed to perform specific tasks or applications for end-users. Examples of application software include word processors, spreadsheet programs, web browsers, etc. While application software interacts with the operating system and may indirectly utilize device drivers, it is not responsible for providing the software interface to hardware devices.

3. Device Drivers:
Device drivers are software programs that enable the operating system to communicate with and control hardware devices. They act as a bridge between the hardware and the operating system, allowing the operating system to access and control the hardware's functions and capabilities. Device drivers provide the necessary software interface for the operating system to send commands, receive data, and manage the hardware resources efficiently.

Device drivers are specific to each hardware device and are often provided by the hardware manufacturer. They are typically installed during the operating system's installation process or can be installed separately later. Device drivers are essential for the proper functioning and compatibility of hardware devices with the operating system.

In summary, the program that provides a software interface to hardware devices is called a device driver.
