Carla, a jump drive is something really small that you connect to your USB port and store stuff on. It is so small that it fits on your key chain. Mine holds 256MB... Same as the hard drive on my BIG computer... I think some call it a memory stick? It is called several things including jump drive. Portable storage? I got it because my old laptop didn't have a burner and I wanted to transfer information on the old one to my new one.
Here are some....
