In the given context, what does the Driver do?

• A. Types the code; enters info on the keyboard
• B. Designs the user interface
• C. Tests the program
• D. Maintains the database

Answer: (A)

A driver is a software component that lets the operating system communicate with a hardware device. It acts as a translator: the OS issues generic commands, and the driver translates them into device-specific signals so the hardware can perform the requested actions. It also handles tasks like initializing the device, performing I/O, and managing interrupts, enabling programs to use hardware without needing to know its details.

This isn’t about typing code, designing the user interface, testing the program, or maintaining a database—those are roles for developers, testers, or database administrators. The driver’s job is specifically to interface with hardware so it can work with the rest of the system.
