FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an analog format. The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector.

Detailed explanation-2: -They are usually connected to the motherboard via a PCI or PCIe card slot. By using these connections, the card can interface with all the power and other contacts to connect to the motherboard: you can just drop the card in the slot, and screw the backplate into place.

Detailed explanation-3: -Sound cards are configured and utilized with the help of a software application and a device driver. The input device attached to receive audio data is usually a microphone, while the device used to output audio data is generally speakers or headphones.

Detailed explanation-4: -A sound card (also referred to as an audio card) is a peripheral device that attaches to the ISA or PCI slot on a motherboard to enable the computer to input, process, and deliver sound.

Detailed explanation-5: -Sound cards contain at least one Digital-to-Analog Converter (DAC) and one Analog-to-Digital Converter (ADC) for each of the two stereo channels, and some contain more. A DAC converts a digital audio stream into the analog audio delivered to the Line-out port.
