Apple ACPT Certifications Exam 9L0-402

This challenge is exacerbated 9L0-509 by the lack of established standards, protocols, and proven methods for preserving digital information[5]. We used to save copies of data on tapes, but media standards for tapes have changed considerably over the last five to ten years, and there is no guarantee that tapes will be readable in the future[6]. Hedstrom further explained that almost all digital library researches have been focused on “architectures and systems for information organization and retrieval, presentation and visualization, and administration of intellectual property rights” and that “digital preservation remains largely experimental and replete with the risks associated with untested methods”. While the rapid advance of technology threats access of digital contents in length, the 9L0-402 lack of digitizing standards affects the issue in width.
