Question: 1 / 400

What type of cable is commonly used for transmitting high-definition video and audio?

Coaxial cable

Ethernet cable

HDMI cable

HDMI cable is the standard for transmitting high-definition video and audio in a single cable. It supports uncompressed digital video, multi-channel audio, and is capable of carrying additional data such as control signals. This makes it particularly advantageous for modern devices, including televisions, Blu-ray players, game consoles, and computers, that require high-quality audio-visual transmission.

While coaxial and component cables can transmit video signals, they do not support the same level of quality and convenience that HDMI offers. Coaxial cables are typically used for data transmission in cable television setups and internet connections, and while component cables can deliver high-definition video by separating video signals into multiple channels, they do not carry audio. Ethernet cables are used primarily for networking and data communication, not for audio-visual transmission. Thus, HDMI cables stand out as the correct choice due to their capability to carry both high-definition video and audio seamlessly.
