Which device typically uses a high-density (three-row) female DB-15 connector?

The device that typically uses a high-density (three-row) female DB-15 connector is a VGA/SVGA monitor. This type of connector is specifically designed for video output, allowing the transfer of analog video signals from the computer to the display. The high-density DB-15 connector is characterized by its arrangement of 15 pins in three rows, which is capable of carrying the RGB (red, green, blue) video signals, as well as horizontal and vertical synchronization signals essential for displaying images accurately on the monitor.

In the context of the other options, network cards usually utilize different types of connectors, such as RJ-45 for Ethernet connections. Audio interfaces typically employ 1/4" jacks, XLR connectors, or other audio-specific connections rather than the high-density DB-15. USB hubs utilize USB connectors, which are completely different in design and function, focusing on data transfer rather than video signal output. Thus, the association of the high-density DB-15 connector with VGA/SVGA monitors is clear and pivotal for understanding how legacy video connections function.
