Users can leave all their peripherals attached to the hub for more convenient connection and detachment. Instead of unplugging multiple items, consumers only have to remove a USB hub's plug. This is perfect for those who need their computers to travel, such as college students who bring their notebooks to class or workers who need their laptops in the office.

If you have too many accessories and not enough docks, a USB hub will provide the additional support you need. A hub uses one USB port on the computer itself but provides multiple ports that link with other devices - much the way a power strip creates additional electrical outlets by working from one.

Industrial USB Hub with 7 Ports feature a rugged metal enclosure.

When you are purchasing a USB hub, pay attention to both the number of additional USB ports that the hub will provide and whether or not it is a powered hub. You'll know that it's a powered hub if it comes with a power adapter. Devices such as portable music players require a certain amount of power to be provided by the USB hub. Since you're splitting the power from one USB port on your computer across all of the ports on your hub, a powered hub is required to provide certain devices with enough power to communicate with your computer.

It's generally a good idea to choose a port on the back of the computer so the wire isn't visible. It doesn't matter which port you choose. If all of your ports are currently in use, simply pick a device, unplug it from your computer and plug it into the USB hub; it should be back up and running as soon as you plug the USB hub into your computer.
