Which input device is used to read a barcode?

Answer and explanation

Correct answer: Barcode Scanner

The governing concept is input devices. A barcode scanner uses light or an imaging sensor to detect the bars and spaces in a printed or displayed barcode, then converts that pattern into digital data for the computer. A projector and speaker are output devices, while a plotter produces printed drawings. Since the scanner reads information into the system, the barcode scanner is the correct answer: option A.
