SOUND+CARD

SOUND CARD The Sound Card, also called the Audio Card or Audio Device, is a thin plastic PCB or sometimes an external attachment that acts as a dedicated CPU for calculation of audio information.

A sound card typically plugs into the motherboard through a PCI slot, or in some cases as a peripheral, and usually has no heatsink or fan, as it does not require the same level of cooling as other major components.

Some motherboards have built‐in audio functionality that works in much the same way as a sound card, but is referred to as Onboard Audio or Integrated Sound. PCs with such audio functionality typically (if enabled) process audio‐related information less quickly or less faithfully than those using plug‐in sound cards. In human body terms, the sound card is much like the portion of the Brain that relates to audio interpretation.
