Chapter 3 Using Your Computer 25
Using Multiple USB Devices at the Same Time
If all of your USB ports are being used and you want to connect more USB devices,
you can purchase a USB hub. The USB hub connects to an open USB port on your
computer and provides additional USB ports (usually four or seven). Most USB hubs
also have a power adapter and should be plugged into an outlet.
