Which Of The Following Are True About DVI And HDMI Technology? (Select Two.)
A HDMI Can Transmit Video In Either Digital Or Analog.
B HDMI Can Transmit Audio Data.
C DVI Can Transmit Video In Either Digital Or Analog.
D DVI Can Transmit Audio Data.
The correct answer and explanation is :
The correct answers are:
B. HDMI can transmit audio data.
C. DVI can transmit video in either digital or analog.
Explanation:
HDMI (High-Definition Multimedia Interface) and DVI (Digital Visual Interface) are both standards used to transmit video signals from a source (like a computer or media player) to a display (like a monitor or TV). While they look similar and are sometimes used interchangeably with adapters, they have key differences.
✅ B. HDMI can transmit audio data
This statement is true. One of the major advantages of HDMI over DVI is its ability to transmit both high-definition video and audio signals through a single cable. HDMI supports up to 8 channels of uncompressed digital audio and is commonly used in home entertainment systems, TVs, gaming consoles, and Blu-ray players for this reason. This capability simplifies cabling by removing the need for a separate audio cable.
✅ C. DVI can transmit video in either digital or analog
This is also true. DVI is versatile in that it supports both digital and analog video signals. There are three main types of DVI connectors:
- DVI-D (Digital only)
- DVI-A (Analog only)
- DVI-I (Integrated, both digital and analog)
Because of this, DVI can interface with older VGA (analog) monitors using a passive adapter, making it useful for compatibility across various generations of display technology.
❌ A. HDMI can transmit video in either digital or analog
This is false. HDMI is strictly a digital signal interface. It does not support analog video transmission. All devices using HDMI must support digital output/input.
❌ D. DVI can transmit audio data
This is false. Standard DVI does not support audio transmission. It is designed to carry only video signals. Some graphics cards may transmit audio through a DVI-to-HDMI adapter, but this is not a native feature of the DVI standard.
