Question 1

What is the primary difference between 'lossy' and 'lossless' compression in document imaging?

Accepted Answer

Lossy compression permanently discards image data, while lossless preserves all original data

Answer

Lossy compression reduces file size by permanently removing image data, while lossless compression reduces file size without losing any original information, allowing perfect reconstruction.

Question 2

Which scanner technology uses a row of light-sensitive elements that spans the full width of the document to capture an image in a single pass?

Accepted Answer

CCD (Charge-Coupled Device) linear array scanner

Answer

CCD linear array scanners use a full-width row of charge-coupled device sensors to capture one line of a document at a time as the scanning element moves across the page.

Question 3

When a CDIA architect specifies a 'capture workstation,' which of the following is a critical performance consideration?

Accepted Answer

Processor speed and RAM for real-time image processing and indexing

Answer

Capture workstations performing real-time image enhancement, OCR, and indexing require adequate CPU processing power and RAM to avoid bottlenecks in high-volume scanning operations.

Question 4

A document imaging project requires that scanned images be searchable without storing separate extracted text files. Which format best fulfills this requirement?

Accepted Answer

Searchable PDF (PDF with embedded text layer)

Answer

Searchable PDF embeds an OCR-generated text layer behind the visible image, enabling full-text search while maintaining the original document appearance in a single file.

Question 5

What does 'throughput' measure in the context of a document scanner?

Accepted Answer

The number of pages the scanner can capture per minute or hour

Answer

Scanner throughput measures how many pages the device can scan in a given time period (pages per minute or images per minute), directly affecting processing capacity.
