The sound card is an expansion card that allows the computer to send audio information to an audio device such as speakers, headphones, etc.
What is an audio interface and what do we do with it?
There are many uses for a sound card, such as hearing sound from a video game, listening to music or movies, having text read aloud, and so on. As useful as these tasks are, the sound card, unlike the CPU and RAM, is not a necessary piece of hardware for a computer to function.
Sometimes the terms sound card, audio adapter, and sound adapter are used instead of sound card.
A sound card is a rectangular piece of hardware with many contacts on the bottom of the card and several ports on the sides for connecting to audio devices, such as speakers.
