When should I use emulators or simulators?

What’s the difference between emulators and simulators?

Emulators replicate the hardware and software of a system, while simulators mimic the behavior of a system without replicating its hardware.

When should I use an emulator instead of a simulator?

Use an emulator when you need to test software in an environment that closely resembles the actual hardware. Simulators are better for testing scenarios where hardware specifics are less critical.

Can you give me examples of when to use each?

Sure! Use an emulator for mobile app development to test on different devices. Use a simulator for flight training where the focus is on procedures rather than the actual aircraft.

Are there any performance differences between the two?

Yes, emulators can be slower because they replicate hardware, while simulators are generally faster as they focus on behavior.
