Which of the following describes input devices?

• A. Keyboards, mice, scanners, cameras, joysticks, and microphones.
• B. Screens and printers only.
• C. External storage drives.
• D. Network routers and switches.

Answer: (A)

Input devices are hardware that let you send information to the computer. Keyboards provide typed input, mice and joysticks control the cursor or game actions, scanners convert physical documents into digital data, cameras capture images, and microphones record audio. These are all examples of input devices because they bring data into the system for processing. The other items described—screens and printers—are output devices, since they display results or produce physical copies. External storage drives are for saving data rather than entering it, and network routers and switches manage data flow between devices rather than providing input. So the set that includes keyboards, mice, scanners, cameras, joysticks, and microphones correctly describes input devices.
