Included are systems specifications, file specifications, codebooks, record layouts, user guides, and output specifications.
DOS. An acronym for Disk Operating System - the system which manages all of the functions of a computer.
Electronic record. Any information that is recorded in a form that only a computer can process and that satisfies the definition of a Federal record in 44 U.S.C. 3301 (see also definitions for "record" and "nonrecord" in 280 FW 1.
Electronic records system. Any information system that produces, manipulates, or stores Federal records by using a computer.

EBCDIC. Extended Binary Coded Decimal Interchange Code. A binary code representing each letter, number, or other symbol with a unique 8-bit code.
File. In electronic recordkeeping, an organized collection of related data arranged into records that are stored together and stored as a unit.
Finding aids. Indexes or other lists, whether manual or automated, that are designed to make it easier to locate relevant files or retrieve information.
Format. In electronic recordkeeping, the arrangement of data for computer input or output, such as the number and size of data fields in a logical record or the spacing and letter size used in a document.
Hard copy. Recorded information copied from a computer onto paper or some other durable surface, such as microfilm. To be distinguished from a temporary image an a display screen and from the electronic information an a magnetic tape or disk(ette) or in the computer's main memory.
Information system. The organized collection, processing, transmission, and dissemination of information in accordance with defined procedures, whether automated or manual. (See also Office of Management and Budget Circular No. A-130.
Inventory. A survey of agency records and nonrecord materials that is conducted primarily to develop records schedules and also to identify various records management problems, such as improper applications of recordkeeping technology.
LAN. Local Area Network, also known simply as network, is a configuration that allows several computers to talk to one another, access everyone's file and use the same printer.
Life cycle of records. The management concept that records pass through three stages: creation, maintenance and use, and disposition.
Local Area Network. See LAN.
Logical record. A collection of related data elements, referring to one person, place, thing or event, that are treated as a unit and have either a fixed or variable length.
Optical character recognition (OCR). A method of entering data into a computer by using an optical scanning device to read the contents of documents.
Optical disk. Also identified as "OD." A noncontact, random-access disk tracked by optical laser beams and used for mass storage and retrieval and digitized text and graphics. Information is recorded on a heat-sensitive material via a computer controlled laser beam which either melts the sensitive material or changes its color. This technology allows "reading" but not modification of large amounts of information making it suitable for short-term storage of high volume information for which active retrieval is a factor. Types include WORM (write once read many), CD-ROM (compact disc-read only memory), and compact disc-interactive).
Output records. In electronic recordkeeping, information generated by a computer and placed on an outside medium, such as paper, microform, or an electronic storage medium.
Processing files. In electronic, recordkeeping, those data files comprising the life cycle of most computerized records before the production of a particular master file. Includes work files, test files, input source files, intermediate input/output files, and valid transaction files.
Portability. An electronic storage medium that will run on equipment offered by multiple manufacturers and can be transferred from one medium to another.
Record layout. A diagram or list of the contents of a logical record describing each data field's informational content, length, and position.
Records schedule. A document providing authority for the final disposition of recurring or nonrecurring records. Also called records disposition schedule, records control schedule, records retention schedule, or schedule. Includes the SF I 1 5, the General Records Schedules, and the agency records schedule, which when completed becomes a comprehensive records schedule that also contains agency disposition instructions for nonrecord materials.
Sensitive information/Data. Any information or data which requires a degree of protection due to the risk and magnitude of loss or harm that could result from inadvertent or deliberate disclosure, alteration, or destruction of the data. This includes data affecting the mission of the Service and or the Department; personal data requiring protection under the Privacy Act; data contained in automated decision-making applications; financial data which could result in loss to the Government; proprietary data warranting special protective measures, and any other data the protection of which is determined to be in the best interest of the Government.
