Which of the following best describes the challenges associated with maintaining digital information?
Which of the following best describes the challenges associated with maintaining digital information?
- Digital information inherently lasts longer than physical documents because digital storage does not degrade over time, reducing preservation efforts and costs.
- The obsolescence of hardware and software and the degradation of storage media makes digital preservation a complex and ongoing task requiring migration to new formats. (correct)
- The legal risk of maintaining digital archives and data is reduced because electronic records are not discoverable in legal proceedings, simplifying information governance.
- Digital information is straightforward to preserve due to standardized formats which require no special tools or updates to remain accessible and usable over decades.
What primary strategy is used to preserve digital information against format obsolescence?
What primary strategy is used to preserve digital information against format obsolescence?
- Bit-level preservation, which ensures the original binary data remains unchanged, regardless of software or hardware updates.
- Migration, which periodically converts digital information into updated formats to ensure compatibility with current software and hardware. (correct)
- Emulation, which involves transforming digital objects into static image files to ensure visual consistency over time.
- Cold storage, which involves archiving digital data on offline media and only accessing it every few years to prevent degradation.
Which approach offers the most comprehensive protection against data loss but requires significant storage capacity?
Which approach offers the most comprehensive protection against data loss but requires significant storage capacity?
- Checksum verification, which ensures data integrity through regular audits, but does nothing directly to address or counter actual data loss.
- Multiple copies in diverse locations, which duplicates data across different sites to protect against localized disasters; this minimizes risk but increases expenses. (correct)
- Regular backup, which involves continuously backing up all files rather than just the most recent versions; this ensures minimal data loss.
- Data compression, which reduces storage needs by permanently removing redundant information; it balances risk and cost.
