A USB hub is a handy way of adding additional USB ports to a setup. They're the USB version of a regular plug extension lead, converting a single USB socket into a hub of them. You plug it into your computer, then use the additional ports to use mice, keyboards, and other USB devices all from a single port.
Much like extension leads, USB hubs also have limitations. You can't load too many power-hungry devices onto it, else difficulties arise. However, if you want to use a keyboard, mouse, and a phone charger on one USB port, a hub can achieve this.
