A USB flash drive, or "The Stick", is used for storing data. They're easy to use - just plug it into the USB port on your computer. If your computer doesn't have the driver, and you are hooked up to the Internet, your computer will find and download the driver for you. Your computer may do this automatically - you may not even know it's done it. Depending on the size of your USB flash drive, you can store whatever you want on it - data files, photos, music....your choice. Just make sure the light on it goes out before removing it.
