plug-and-play portable storage device that uses flash memory and is
lightweight enough to attach to a keychain. A USB drive can be used in
place of a floppy disk, Zip drive disk or CD. When the user plugs the
device into the USB port, the computer's operating system recognizes the
device as a removable drive and assigns it a drive letter.
