emulators

computing: software: emulators An emulator is any system (host) which pretends to be a different system (target) in order to allow software designed for the target system to run on the host system.

This section also covers compatibility layer software. Although technically different from an emulator, a compatibility layer nonetheless emulates one system while running it in another.
