Which device is used to input data into a computer (examples include keyboard, mouse, microphone, scanner)?

• A. Input Device
• B. Output Device
• C. RAM
• D. Hard Drive

Answer: (A)

Input devices are hardware that bring data into a computer from the outside world. They convert human actions or external signals into digital data the computer can understand and process. That’s why a keyboard, mouse, microphone, and scanner fit here—they capture information from you or the environment and translate it into a form the computer can work with.

In contrast, output devices like monitors or printers take data from the computer and present it to you. RAM is temporary memory the computer uses while processing, and a hard drive is long-term storage. The question is asking for the type of device that adds data to the computer, which is an input device.
