Which of the following are input devices?

• A. Monitor
• B. Speaker
• C. Printer
• D. Keyboard and mouse

Answer: (D)

Input devices are tools you use to send information into a computer. The keyboard and mouse fit this role because they capture your actions—typing keystrokes and moving or clicking the mouse—and convert them into data and commands the computer processes. In contrast, the monitor displays output from the computer, the speaker plays audio, and the printer prints a physical copy of data. So the combination of keyboard and mouse is the correct example of input devices.
