Description
A USB hub is a device that expands the number of available USB ports on a computer or other electronic device. It allows multiple USB devices to be connected and used simultaneously, even if the device has limited built-in USB ports. USB hubs come in various sizes and designs, ranging from small portable hubs with a few extra ports to larger hubs with numerous ports for connecting multiple devices. They typically have one upstream port that connects to the computer or device, and multiple downstream ports for connecting peripherals such as keyboards, mice, printers, external hard drives, cameras, and more. USB hubs are commonly used in offices, homes, and other settings where there is a need to connect multiple USB devices to a single computer or device. They provide convenience by eliminating the need to constantly plug and unplug devices from limited USB ports. Additionally, some hubs offer features like data transfer speeds up to 10 Gbps (USB 3.1) or power delivery capabilities for charging devices. Overall, a USB hub is an essential accessory for expanding connectivity options and managing multiple USB devices efficiently.
