Which device is not typically used as an input device?

• A. Stylus
• B. Scanner
• C. Printer
• D. Webcam

Answer: (C)

The key idea is distinguishing devices that bring information into the computer from those that output information. A stylus feeds handwriting or drawings into the computer by touching a surface; a scanner converts physical documents into digital data; a webcam captures video or images to be processed by the computer. A printer, on the other hand, takes digital data from the computer and produces a physical copy. That makes it an output device. Some printers have scanning or fax capabilities, but their primary role is to output, not input.
