  1. Access Control
    a means of controlling output by securing access to the system itself and limiting it to authorized end users
  2. Androids
    robots that are made to look human
  3. Audio and video output
    output that uses sounds and/or images to present information
  4. Backup file
    a copy of an entire file, or any changes to that file since the last backup maintained so that any event causing loss of current data can be mitigated by restoring the data from the backup file.
  5. Bias
    notion that the output from a system is not always viewed as a neutral outcome of an IS by the end user and that certain design elements can actually introduce particular biases that may cloud the decision process.
  6. Completeness controls
    controls that help to ensure that the output being viewed is both accurate and timely to the extent that the data used to create it are accurate.
  7. Computer output microfilm (COM)
    a roll of photo graphic film that can contain a large volume of paper-based or computer-generated reports and records in miniature form.  A special reading device is used to locate the desired page and magnify it so that it can be easily read or converted into hard copy.
  8. Detailed report
    a report designed to present data or information with only a minimum amount of filtering.
  9. Differential backup
    a backup strategy based on the backup of all modified files since the previous full backup; a variation of the incremental backup strategy.
  10. Disaster recovery plan
    a comprehensive statement of consistent actions to be taken before, during, and after a disaster to ensure the continuity of operations and availability of critical computing resources in the event of a disaster.
  11. Distribution control lists
    lists used to limit access to certain output to a predefined set of end users.
  12. Division of labor
    an approach to output control that involves the creation of separate activities, performed by separate individuals, such that autonomous control over the creation and generation of output cannot be achieved by a single person.
  13. Exception report
    an internal output that contains filtered information intended to report events or transactions that require special attention or that fall outside some pre-established operating guideline or parameter.
  14. External output
    output that leaves the boundary of the system and serves to either confirm a system action to the recipient or trigger an action on the part of a recipient.
  15. Generational backup
    a backup strategy that uses a system of tape rotation via three storage sets.  The first set is called “grandfather,” the second “father,” and the third “son.” Also referred to as grandfather-father-son (GFS).
  16. Graphical format
    an output format in which the numbers are represented by one of a wide variety of charts or graphs.
  17. Hard copy
    the printed version of a document.  Also known as paper-based output.
  18. Human-machine boundary
    the points where an end user interacts with the system through the exchange of data or information.
  19. Impact printing
    generating hard copy by means of printers that actually strike the paper to transfer the ink.
  20. Incremental backup
    a backup strategy that establishes a repetitive cycle that begins with a full backup of all data files and continues through a series of incremental backups.
  21. Internal output
    output that normally stays within the system boundary and is used to support the organizational responsibilities and activities of the end users.
  22. Laser
    a device that produces a high-intensity, directional, monochromatic beam of light.  The acronym stands for light amplification by stimulated emission of radiation.
  23. Microfiche
    a variation of COM that stores the output on a single sheet of film rather than a continuous roll.
  24. Narrative approach
    an output format in which information is presented using conventional sentences and paragraphs.
  25. Nonimpact printing
    generating hard copy by means of printers that use inkjet or laser technology and do not touch the paper to transfer the ink.
  26. Online backup system
    a backup system that can automatically detect files on an organization’s computer network that require backup, encrypt those files for security, compress the encrypted files, and transmit the data through high-speed point-to-point telecommunications lines to an online data vault at a secure facility.
  27. Phonemes
    vowel and consonant sounds.
  28. Range-of-value limits
    a range of values that constitutes the set of legal values for a particular piece of data.
  29. Robotics
    vehicles for complex output intended to automate production, manufacturing, distribution, and any application requiring precise and accurate handling of physical components.
  30. Screen-based output
    output that is viewable on a computer screen.
  31. Speech synthesis and recognition
    audio output technology that mimics human speech.
  32. Storage set
    the complete set of tapes or disks representing the backup from a system.
  33. Summary report
    a report generated to allow end users to review information in a filtered or categorized form in situations where the details are too cumbersome to review or are not necessary.
  34. Tabular approach
    an output format that organizes the information into columns and rows very similar to the organization of the relational data model.
  35. Turnaround document
    output designed to leave the system as output and then trigger an action on the part of the recipient that results in input reentering the system at a later time.
  36. Zoned approach
    an output format that organizes the output into predetermined zones on the paper or screen.  This is similar to the look and feel of a frame-based Web page or a typical newspaper.
