What is the difference between HDMI and USB port?

When it comes to connecting devices, we often encounter various ports and cables. Two commonly used ports are HDMI (High-Definition Multimedia Interface) and USB (Universal Serial Bus). Although they may appear similar and are used for connecting devices, there are several key differences between these two ports.


HDMI is a digital interface used primarily for audio and video transmission. It provides a high-definition and uncompressed connection, making it ideal for connecting devices such as televisions, monitors, projectors, and audio systems. HDMI cables are typically used to transmit high-quality audio and video signals from a source device to a display device.

USB Port

USB is a standard interface used for connecting various devices, including printers, keyboards, mice, external storage devices, and smartphones. Unlike HDMI, USB is a versatile port that supports the transfer of data, power supply, and connection to a wide range of peripherals. USB ports are commonly found on computers, laptops, and even some televisions.
