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.
BITCURATOR Environment is a Ubuntu-derived Linux distribution geared towards the needs of archivists and librarians. It includes a suite of open source digital forensics and data analysis tools to help collecting institutions process born-digital materials.
BITSTREAM: A sequence of bytes, which has meaningful common properties for the purposes of preservation. A bitstream may be a file or a component of a file.

DIP (Dissemination Information Package): An external representation of an object exported from the Digital Preservation Repository, optionally including an Archival Information Package, Submission Information Package, and object metadata. See also AIP and SIP.
ePADD is a software package developed by Stanford University's Special Collections & University Archives that supports archival processes around the appraisal, ingest, processing, discovery, and delivery of email archives. ePADD Phase 2 is being developed from 2015-2018 by staff of the Department of Special Collections and University Archives, Stanford University Libraries (SUL), Stanford University, in collaboration with partners at Harvard University, the Metropolitan New York Library Council (METRO), University of Illinois at Urbana-Champaign, and University of California, Irvine.
EMULATION: The imitation of a computer system, performed by a combination of hardware and software, that allows programs to run between incompatible systems. Or, the ability of a program or device to imitate another program or device.
FC5025: Device Side Data's FC5025 USB 5.25" floppy controller plugs into any computer's USB port and enables you to attach a 5.25" floppy drive. Compatible with TEAC FD-55GFR or equivalent drive (not included with the FC5025).
FEDORA (http://www.fedora-commons.org/) (Flexible Extensible Digital Object Repository Architecture) is a software framework to construct and maintain repositories of digital objects.

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.
FRED (Forensic Recovery of Evidence Device): The FRED family of forensic workstations (produced by Digital Intelligence of New Berlin, WI) are highly integrated, flexible and modular forensic platforms. Available in mobile, stationary and laboratory configurations, these systems are designed for both the acquisition and examination of computer evidence.

JPEG 2000 is a wavelet-based image compression standard. It was created by the Joint Photographic Experts Group committee in the year 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created about 1991). The standardized filename extension is JP2.
KRYOFLUX is a USB-based hardware and software solution for preserving software on floppy disks. It was developed by the Software Preservation Society. Works with all major 3.5" and 5.25" drives; works well with selected 3" (e.g. Amstrad FDI-1) drives; also works with 8" (e.g. Shugart 851; might require additional adapter) drives; other types of drives and media currently under investigation.
