n.a component of a digital preservation strategy in which obsolete file formats are rendered accessible by replicating their original digital or hardware environmentUS GAO 2002, 45A proposed approach to the problem of software and hardware dependence is emulation, which aims to preserve the original software environment in which records were created. Emulation mimics the functionality of older software (generally operating systems) and hardware. . . . This technique seeks to recreate a digital document’s original functionality, look, and feel by reproducing, on current computer systems, the behavior of the older system on which the document was created.
Frequently discussed together in the archival literature, emulation and migration are two different methods by which access to records in obsolete file formats may be obtained.
