Emulators and simulators are software tools that mimic other systems. They allow testing and development without physical hardware. Developers use these tools to test applications across different devices. Emulators replicate specific devices or platforms. Simulators model the general behaviours of systems.
Features:
1. Reproducing hardware or software environments
2. Enabling testing on various configurations
3. Supporting debugging and development
4. Reducing costs associated with physical hardware
Common Types:
1. Mobile device emulators
2. Game console emulators
3. Network simulators
4. Flight simulators
Emulators and simulators have limitations. They may not perfectly replicate real-world conditions. Performance can differ from actual hardware.
