USB Hub is a device that expands a single USB port into multiple ports, allowing users to connect multiple peripherals such as flash drives, keyboards, mice, and external hard drives to a computer or other USB-enabled device. It can be bus-powered (drawing power from the host device) or self-powered (using an external power adapter). USB hubs come in various versions, including USB 2.0, USB 3.0, and USB-C, offering different data transfer speeds and functionalities. They are commonly used for increasing connectivity in laptops, PCs, and gaming consoles.
