Correct Answer:
C. Printer
Computer hardware is categorized into input and output devices based on their function. Output devices are components that receive processed data from the computer and present it to the user in a human-understandable format, such as visual, audio, or printed form. Input devices, conversely, send data or commands into the computer.
The correct answer is C: Printer. A printer is a classic output device because it takes digital information from the computer and converts it into a physical, tangible hard copy on paper. This action presents the computer's processed data to the user.
- A: Mouse is an input device, used to control the cursor and interact with graphical interfaces.
- B: Scanner is an input device, converting physical documents or images into digital data.
- D: Keyboard is an input device, used for typing text and commands into the computer.
Therefore, only the printer functions to output information from the computer.
