Input Devices: which of the following is an input device?

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

Answer: (B)

Understanding input versus output devices. An input device is used to send information into the computer. A keyboard fits this role because pressing its keys lets you enter text, numbers, and commands that the computer processes. The other options are output devices: a speaker produces sound from the computer’s data, a monitor displays visual output, and a printer creates a physical copy of digital information. So the keyboard is the device that introduces data into the system, making it the correct choice.
