  1. What is a 'WORM' storage device as used in document management?

    Answer: Write Once Read Many — a storage medium where data can be recorded once but read unlimited times

    WORM storage allows data to be written once and read many times without modification, making it ideal for regulatory compliance and tamper-evident archiving.

  2. Which document imaging quality metric measures the sharpness of edges between black and white areas in a scanned image?

    Answer: Modulation Transfer Function (MTF)

    MTF quantifies how well a scanner reproduces contrast at varying spatial frequencies, directly indicating edge sharpness and detail resolution.

  3. In a document management system, what is 'version control'?

    Answer: Tracking changes to documents over time by maintaining multiple historical versions

    Version control maintains a history of document revisions so that previous versions can be retrieved and changes can be audited over time.

  4. What role does a 'document imaging pilot project' serve before full-scale deployment?

    Answer: It tests the workflow, equipment, and quality standards on a representative document sample to identify issues before full rollout

    A pilot project validates assumptions about volume, quality, indexing accuracy, and workflow efficiency on real documents at manageable scale before committing to full deployment.

  5. Which compression algorithm is used by PDF/A for lossless compression of document images within the archival PDF standard?

    Answer: CCITT Group 4 for bitonal and Flate (ZIP) for continuous-tone content

    PDF/A uses CCITT G4 for bitonal content and Flate (zlib/ZIP) compression for grayscale and color content to ensure lossless archival quality.

  6. What is the significance of maintaining an 'audit trail' in a document imaging system?

    Answer: It records all system and user actions (access, modifications, deletions) to support accountability and legal admissibility

    An audit trail provides a chronological record of who accessed or modified documents, which is critical for regulatory compliance and establishing legal admissibility of records.

  7. What does 'DPI' stand for and what does it measure in document scanning?

    Answer: Dots Per Inch — the number of individual sample points captured per linear inch of the original document

    DPI (dots per inch) measures scan resolution — specifically how many pixels are captured per inch of the original, determining how much detail the digital image contains.
