Digital preservation aims to ensure that digital information remains accessible and usable over time, regardless of changes in technology or media formats.

Data encryption is not typically used for digital preservation, as it can make it difficult to access the data in the future if the encryption key is lost.

One of the main challenges in digital restoration is identifying and locating damaged digital information, as it can be difficult to distinguish between intentional changes to the data and unintentional damage.

Data restoration is not typically considered a type of digital restoration, as it involves recovering lost or damaged data rather than restoring damaged digital information.

Metadata is essential for digital preservation as it helps to identify and locate digital information, provides information about its creation and modification, and helps to ensure its authenticity.

PDF is not a common format for storing digital information, as it is primarily used for representing documents rather than multimedia content.

A checksum is used in digital preservation to detect errors in digital information by comparing the original checksum with the checksum of the preserved copy.

Optical discs are not as commonly used for digital storage as they were in the past, due to their limited capacity and susceptibility to damage.

Cloud storage offers several advantages for digital preservation, including cost-effectiveness, enhanced security, and easy access to digital information from anywhere.

Intentional sabotage or cyberattacks are not typically considered a common challenge in digital preservation, as they are less likely to occur than other factors such as obsolescence of technology and media formats.

Standards play a crucial role in digital preservation by ensuring that digital information is stored in a consistent and accessible format, helping to identify and locate digital information, and providing guidance on how to restore damaged digital information.

Data encryption tools are not typically used for digital preservation, as they can make it difficult to access the data in the future if the encryption key is lost.
