A USB hub is a device that allows multiple USB peripherals to be connected to a single USB port on a computer. This is achieved by increasing the number of USB ports available for use. USB hubs come in various sizes and form factors, ranging from compact and portable to larger desktop models with multiple ports. They are especially useful for laptops and computers with limited USB ports. USB hubs can be powered by the computer's USB port or through an external power supply. Some advanced USB hubs also offer additional features like charging ports, data transfer speeds, and built-in card readers.
