What is a USB Hub?


Definition: A USB hub is a device that features several different USB ports. Since many computer peripherals require USB ports to operate, it’s easy for your computer to run out of available ports. A USB hub will take one single port and turn it into three or four (or more) ports. Sometimes a USB hub is just that -– a series of ports, like a power strip —- while other devices might feature USB hubs built into them for added functionality.
