Apple ACPT Certifications Exam 9L0-402

Another strategy for 9L0-509 digital preservation is to preserve digital information in the simplest possible digital formats in order to minimize the requirements for sophisticated retrieval software. Digital information can be transferred across successive generations of technology in a "software-independent" format as ASCII text files or as flat files with simple, uniform structures. Several data archives hold large collections of numerical data that were captured on punch cards in the 1950s or 1960s, migrated to two or three different magnetic tape formats, and now reside on optical media. As new media and storage formats were introduced, the data were migrated without any significant change in their logical 9L0-402 structure. This approach has the distinct advantage of being universal and easy to implement. It is a cost-effective strategy for preserving digital information in those cases where retaining the content is paramount, but display, indexing, and computational characteristics are not critical. As long as the preservation community lacks more robust and cost-effective migration strategies, printing to paper or film and preserving flat files will remain the methods of last resort for many institutions and for certain formats of digital information.
