Which component typically connects to the HDMI port?

The correct response is that a monitor typically connects to the HDMI port. HDMI, or High-Definition Multimedia Interface, is a standard used for transmitting both high-definition video and audio signals between devices. Monitors utilize HDMI connections to receive video signals from various sources, such as computers, gaming consoles, and other multimedia devices, allowing for the display of high-quality visuals.

In contrast, the other options listed do not commonly use an HDMI port for connection. A power supply is responsible for providing electrical power to a device and does not have data or video output capabilities. Keyboards and mice interface with computers through USB or wireless connections, relying on signals that do not require high-definition video output. Thus, the relationship between monitors and HDMI ports is a fundamental aspect of modern electronic connectivity, highlighting why the monitor is the correct answer.
