CompTIA A+ | Microsoft MTA O/S: Sound cards

Posted filed under CompTIA A+, MICROSOFT MTA O/S.

Sound cards connect as x1 PCIe or PCI cards and normally have PC 99 color-coded 1/8” mini-jacks for I/O and speakers, and optical I/Os known as S/PDIF (example: TOSLINK).

 

Alternatively referred to as an audio output device, sound board, or audio card. A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another, either in an expansion slot (sound card) or on the motherboard (onboard).
