USB hubs put additional USB ports right on your desktop. No more fumbling around behind your computer every time you want to plug in a USB device... just plug it into the USB hubs! Just as you would add a power bar for additional outlets, USB hubs let you to do same except to add more USB ports for peripheral connections. Other more advanced USB hubs combine with serial, parallel, Ethernet and maybe USB audio / video output to form a brand-independent laptop docking station.
