Which of the following video card connectors provides digital video output?

VGA
DVI-D
Composite
S-Video

The correct answer is: DVI-D

The connector that provides digital video output is DVI-D. This type of Digital Visual Interface (DVI) connector transmits digital video signals without the need to convert the signal to analog, which can result in better image quality. DVI-D is specifically designed for digital displays, allowing for high-resolution output without degradation of the signal. In contrast, VGA, Composite, and S-Video connectors are all analog connections, which means they transmit analog video signals. These analog formats can lead to decreased image quality when compared to a digital signal, making them less suitable for modern high-definition displays. While they may still be used in specific applications, they do not offer the same level of performance as DVI-D when it comes to digital video output.
