In order to play or hear sound on a computer, one needs:
- A.
Video Card
- B.
Memory
- C.
Processor
- D.
Sound Card/Speaker
Correct Answer
D. Sound Card/SpeakerExplanation
To play or hear sound on a computer, a sound card or speaker is required. A sound card is a hardware component that allows the computer to process and output audio signals. It converts digital data into analog signals that can be played through speakers or headphones. Without a sound card, the computer would not be able to produce any sound. Speakers, on the other hand, are the output devices that convert the electrical signals from the sound card into audible sound waves. Both the sound card and speakers are necessary components for playing or hearing sound on a computer.Rate this question:

When you save a file it is permanent save to:
- A.
Memory
- B.
CPU
- C.
Processor
- D.
