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

Physical deterioration is a challenge associated with preserving physical artifacts, not digital resources. Technological obsolescence, format diversity, and lack of metadata are common challenges in digital preservation.

Preserving digital heritage is important for future generations because it provides access to valuable information, aids research and scholarship, and promotes cultural diversity and understanding.

Storing digital resources in a single, centralized location is not recommended as it increases the risk of data loss in case of a disaster or system failure. Distributing copies of digital resources across multiple locations is a more secure approach.

Metadata plays a crucial role in digital preservation by providing information about the context, content, and structure of digital resources, aiding in their organization and retrieval, and ensuring their authenticity and integrity.

The Library of Congress, the National Archives and Records Administration, and the Internet Archive are all examples of digital preservation repositories that collect, preserve, and provide access to digital resources of historical and cultural significance.

Digital migration refers to the process of converting digital resources from one format to another to ensure their continued accessibility and usability over time.

ISO 14721, OAIS, and PREMIS are all widely recognized digital preservation standards that provide guidelines and best practices for preserving digital resources.

Digital emulation involves simulating the behavior of obsolete hardware or software to enable the execution of digital resources that were created for those specific environments.

Social media platforms present unique digital preservation challenges due to their rapidly changing policies and algorithms, lack of control over user-generated content, and the ephemeral nature of posts.

Contextual preservation refers to the practice of preserving digital resources along with their associated metadata and contextual information to ensure that they remain meaningful and understandable over time.

Born-digital records often lack proper documentation and metadata, are created in rapidly changing file formats, and may rely on proprietary software, all of which pose challenges for their long-term preservation.

Digital appraisal involves the systematic evaluation and selection of digital resources based on their historical, cultural, or research value to determine which ones should be preserved.

Regularly updating digital resources is not a common digital preservation strategy. The goal of digital preservation is to ensure the long-term accessibility and usability of digital resources, and frequent updates may compromise the integrity and authenticity of the original resources.

Digital authentication involves verifying the authenticity and integrity of digital resources by checking their origin, content, and structure to ensure that they have not been tampered with or altered.
