Developers can try out how and whether their app designs work. Users can also produce learning videos and tutorials in the virtual system environment. For example, an emulated operating system is a safe and virus-free environment for testing apps from unknown sources. A program like Oracle's Virtual Box, for example, is able to simulate a Linux system as a guest system on a Windows host using special virtualization technology.Įmulators can be used in many ways. Often emulators work on the basis of virtualization and with so-called virtual machines. The practice uses different procedures for emulations. With the help of an emulator, a Linux application can be explored and tested in a Windows environment, for example. game apps) and operating systems, in which they can be executed without any problems.Įmulations can operate across platforms and overcome the boundaries of system architectures. They suggest a “familiar” operational environment for application programs (e.g.

A well-known example is a flight simulator, which imitates real conditions in pilot training and thus allows for more practical training. As the name suggests, emulators make it possible to digitally emulate and simulate a wide variety of systems.
