HDMI is typically used for which purpose?

HDMI, or High-Definition Multimedia Interface, is primarily designed for transferring uncompressed digital data, specifically optimized for high-definition video and audio. This makes it an ideal choice for connecting devices like televisions, projectors, and gaming consoles, where high quality in both video and sound is crucial. The use of HDMI ensures that the signal remains in digital format throughout the transfer, preserving the integrity and quality of the audio-visual output without compression artifacts.

The other options do not align with the primary function of HDMI. For example, connecting computers to printers typically involves different interfaces, such as USB, which is designed for data transfer between a computer and peripherals. Similarly, connecting microphones to mixers often utilizes XLR or TRS (Tip-Ring-Sleeve) connectors, which are more suitable for audio signals. Lastly, storing digital files involves storage devices such as hard drives or flash drives, not a connection interface like HDMI, which is focused on signal transmission rather than data storage.
