Used by one person to listen to the sounds on a computer.
Correct Answer
B. HeadpHones
Explanation
Headphones are used by one person to listen to the sounds on a computer. They provide a personal audio experience by delivering sound directly to the user's ears. Unlike speakers, which produce sound that can be heard by multiple people, headphones are designed for individual use. A printer and monitor are not related to listening to sounds on a computer.
3.
Electronic devices that emit sound. Everyone can hear when using these.
Correct Answer
A. Speakers
Explanation
Speakers are electronic devices that emit sound and can be heard by everyone when they are being used. They are designed to convert electrical signals into audible sound waves, allowing users to listen to audio or other forms of sound output. Unlike headphones, which are worn over the ears and transmit sound directly to the user, speakers project sound into the surrounding environment, making it audible to a wider audience. Monitors and CPUs, on the other hand, are not primarily designed to emit sound, although some monitors may have built-in speakers.
