Explanation:

- Option 1: Interprets input provided by users into computer usable form.

- This describes how input device drivers work, like keyboards or mice, not output devices.

- Option 2: Interprets computer output into user understandable form.

- This is correct! Output device drivers (like those for printers or monitors) translate the computer's data into signals the device can work with, making the result understandable or usable for the user.

- Option 3: Translates user inputs into output device.

- This mixes up input with output; output drivers don't process user inputs.

- Option 4: Facilitates user to communicate with output device.

- Too vague and general. Device drivers usually work between the OS and device, not directly with the user.
