Digital preservation refers to the processes and strategies used to ensure that digital information remains accessible and usable over time. As technology evolves, files can become obsolete, making it crucial to maintain digital records, such as documents, images, and videos. This involves regularly updating formats, migrating data to new systems, and creating backups to prevent loss. Organizations like libraries and museums often engage in digital preservation to protect valuable cultural heritage. By using techniques such as metadata creation and digital archiving, they help ensure that future generations can access and appreciate important digital content, even as technology changes.
