Which of the following is NOT a document input device in the electronic document management system?

• A. Scanner
• B. Keyboard
• C. Printer
• D. Digital camera

Answer: (C)

Distinguishing input from output devices in an electronic document management system is the key idea. An input device brings information into the system, such as a scanner that digitizes paper documents, a keyboard that lets you type text, or a digital camera that captures images to store electronically. A printer, on the other hand, is an output device: it creates a physical copy from digital data. Since the system is built around electronic documents, a printer does not serve as a document input device, so it’s the correct choice for NOT being an input device.
