USB Drives (also called flash drives, pen drives, and jump drives) are small, portable drives where you can save files.  USB drives are the newer version of a floppy disk, but much, much better.  First of all, they store a lot more files.  Even the smallest USB drive (32MB) holds more information than 20 floppy disks.  The larger ones (1 or 2 GB) will hold much more: pictures, music, video, even programs.  Second of all, they are much more reliable than floppies, which are easily damaged.  Finally, they are small!  You can carry one in your purse, your pocket, even on your keychain!  To learn more about these neat little devices, click here.
