AIP (Archival Information Package): The internal representation of an object into the Digital Preservation Repository, including all data generated upon ingest (e.g., descriptive metadata) needed to manage and preserve it. See also DIP and SIP.
BIT: The fundamental unit of digital information storage, which can have a binary value of either 1 or 0.
BITCURATOR Access project developed tools to help libraries, archives, and museums provide web-based and local access to born-digital materials held on disk images.

FLASH DRIVE: a small device that plugs into computer's USB port and functions as a portable hard drive.
FLIPPY DISKS: People would sometimes fill one side of a 5.25" disk and then flip it over to store more on the other side. Disks used this way are called "flippy" disks. 5.25" disks have a hole, called the index hole, that lets the drive know if the disk is rotating. (The index hole has other purposes also.) The problem with flippy disks is that when the disk is inserted upside-down, the drive cannot see the index hole. Many drives won't read from the disk unless they can see the index hole. There is no recommended drive for reading flippy disks at this time.
FLOPPY DISK, also called a floppy, diskette, or just disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks, initially as 8-inch (200 mm) media and later in 5¼-inch (133 mm) and 3½-inch (90 mm) sizes, were a ubiquitous form of data storage and exchange from the mid-1970s into the first years of the 21st century.
GUI: Graphical user interface; a mouse-based system that contains icons, drop-down menus, and windows where you point and click to indicate what you want to do. All new Windows and Macintosh computers currently being sold utilize this technology.
