Explanation:
The DVI-D is a type of DVI connector. This connector is used only for digital signal connections. DVI-D
connectors come in dual and single links.
The dual link connector contains 24 pins, whereas the single link connector comes with 18 pins.
DVI stands for Digital Visual Interface. It is a standard for high speed, high resolution digital display
invented by Digital Display Working Group (DDWG). DVI accommodates analog and digital interfaces
with a single connector. New video cards have DVI as well as VGA ports built into them. Most of LCD
monitors come with a 15-pin VGA connection cable, even if they are capable of handling digital
signals coming from DVI connections. However, some monitors come with both types of cables. DVI
has three main categories of connectors. They are: DVI-A, DVI-D, and DVI-I. DVI-A is an analog-only
connector, DVI-D is a digital-only connector, and DVI-I is an analog/digital connector. DVI-D and DVI-I
connectors are of two types: single link and dual link. DVI supports UXGA and HDTV with a single set
of links. Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual
links.
Answer option C is incorrect. The DVI-I connector supports both digital and analog signal
connections.
