Correct Answer:
C. Keyboard
Understanding computer peripherals involves distinguishing between input and output devices. Input devices are hardware components that allow users to send data, commands, or signals to a computer for processing. Conversely, output devices receive processed data from the computer and present it to the user in a human-readable or usable form.
The correct answer is C: Keyboard. A keyboard is a quintessential input device, enabling users to type text, numbers, and various commands directly into the computer system. This action sends data to the CPU for processing.
- A: Monitor is an output device, displaying visual information from the computer.
- B: Printer is an output device, producing hard copies of digital documents.
- D: Speaker is an output device, generating audio output from the computer.
Therefore, only the keyboard functions to input information into the computer.
