Sound Cards Vs. Video Cards

Sound cards have audio outputs for speakers or headphones.

Computers depend on sound and video cards to get digital data from the computer to displays and audio devices so users can hear and see media from their computers. These devices range from the most basic to high-end, feature-packed components.

Function

Sound cards and video cards translate information into formats that may be viewed or heard. Sound cards translate data into an audio signal that may be played through speakers, while video cards translate data into a video signal that may be viewed on a monitor.

Types

The most basic types of sound and video cards aren't cards at all, but integrated motherboard components. There are also plug-in cards and external variants of both sound cards and video cards.

Considerations

Sound and video cards may affect computer performance, but users do not need to get the most function-packed cards they can find. Sound and video cards should match user needs. For instance, simple PC users probably don't need a sound card that supports 7.1 channel surround sound.
