A "HDMI cable" is a high-definition multimedia interface cable used to transmit digital audio and video signals between devices such as computers, Blu-ray players, gaming consoles, set-top boxes, and televisions or monitors. It stands for High-Definition Multimedia Interface.

HDMI cables are widely used for connecting various multimedia devices because they offer high-quality audio and video transmission in a single cable. They come in various lengths and specifications, including different HDMI versions (such as HDMI 1.4, HDMI 2.0, HDMI 2.1), which support different features like higher resolutions, refresh rates, and HDR (High Dynamic Range) content.

In general, HDMI cables have become the standard for connecting audio-visual devices due to their convenience, versatility, and high-quality transmission capabilities.
