Which of the following is an example of an input device listed in common examples?

• A. Touch pad
• B. Card reader
• C. Speakers
• D. Monitor

Answer: (B)

An input device is hardware that brings data into a computer for processing. A card reader does exactly that: it reads information from a physical card and sends that data to the computer, enabling actions like payments or authentication. Output devices, on the other hand, provide data from the computer to you, such as speakers or a monitor. A touch pad is also an input device and serves as a common example of a pointing/input device, but the card reader is a clear, straightforward example of input data entering the system.
