Answer 1

The correct answer is Speaker.

Key Points

A speaker is an output device that transforms digital signals processed by the computer's sound card into audible sound waves or audio.
The sound card sends an electrical signal to the speaker, and then the speaker converts this electrical signal into physical vibrations (sound waves) that we can hear.

Additional Information

Device	Input/Output Device	Function / Signal Conversion
Plotter	Output	Plotters convert digital vector images sent from the computer into physical plots on various materials, usually paper or plastic, using pens or other drawing instruments. The computer sends data to the plotter specifying the colors and shapes in the image, and the plotter then creates the image on the output medium.
Graphics Card	Output	The graphics card takes digital visual data from the processor and converts it into a signal that the monitor can display. The resulting output is what you see on your monitor. The graphics card is vital for rendering high-quality images quickly, especially for video games and high-definition videos.
Monitor	Output	The monitor receives digital or analog signals from the graphics card and converts them into visible light displays. In a nutshell, the graphics card translates the data into signals the monitor can use, and the monitor displays these signals as the images you see on the screen.
