A jump drive - also known as a USB drive, flash drive, keychain drive, or disk-on-key - is a plug-and-play portable storage device that uses flash memory and is lightweight enough to attach to a key chain. A jump drive, which looks very much like an ordinary highlighter marker pen, can be used in place of a floppy disk, Zip drive disk, or CD. When the user plugs the device into their USB port, the computer's operating system may recognize the device as a removable drive and assigns it a drive letter. Windows XP will recognized most jump drives and will select and install the proper driver automatically. Windows XP does not have a native driver for all jump drives, however, and may require admin rights for the first installation. Most jump drives will require admin rights if they are being installed on a computer running Windows 2000.
Unlike most removable drives, a jump drive does not require rebooting after it is attached They do not require batteries or an external power supply, and they are not platform dependent.
Jump drives may require a USB Extension Cable when used with our newer DELL computers. Some jump drives are too wide to fit into the USB slot on the front of the computer. Extension cables may solve this issue.
