Emulation

[em-yuh-LAY-shuhn] /ˌɛmjʊˈleɪʃən/

The use of software to recreate the behaviour of an older computer, operating system or device on modern hardware. Emulation allows obsolete software, video games and other digital objects to be accessed and experienced without altering the original files. It is an important digital preservation method for libraries, archives and museums, helping maintain access to digital collections that depend on outdated technologies.
