Explanation

Correct Answer Explanation:

A keyboard is an input device because it allows the user to enter data (text, numbers, commands) into the computer. It converts key presses into signals the CPU can process.

Why the other options are incorrect:

  • Option A: A monitor is an output device — it displays information from the computer to the user, not the other way around.
  • Option B: A printer is an output device that produces hard copies of digital documents. It sends information out from the computer.
  • Option D: A speaker is an output device that produces sound. It cannot send data into the computer.
