You can only usually buy a USB cable up to 5 metres in length, this is because the signal degrades if the cable is any longer but with a long USB extender the signal is boosted so you don't have to be limited by length of your USB cable.

Each extender is 5 metres in length and up to 4 can be connected together to give you a 20 metre extension on your USB devices.

Whether you want to extend the reach of your webcam or simply put your printer, hardrive or scanner further away from your desk, the USB extension cable will do the job.
