Computers are the same way.
Originally created as a silent data processing machine for the workplace, the modern PC has evolved into a multimedia powerhouse. The sound card has played a large role in this experience, ensuring that your PC is anything but silent. As a multimedia hardware peripheral to your computer, the sound card is a printed circuit board containing chips and electronic components necessary for the manipulation and output of sounds. The sound card simply plugs into an empty expansion slot on your motherboard . It functions by converting the digital sounds of your computer into analog signals used by speakers connected to the card.
