Simulation and emulation tools enable developers to test IoT systems before physical deployment.
Detailed Explanation
Simulation tools are software programs that allow developers to create a virtual environment to test their IoT systems without needing the physical devices. This means developers can identify potential issues early in the design process, which saves time and resources. By utilizing these tools, testing can occur in a controlled setting, where various scenarios can be simulated.
Examples & Analogies
Think of simulation tools like a flight simulator for pilots. Before flying a real plane, pilots practice in a simulator to experience different situations, like turbulence or engine failure, without any risk. Similarly, IoT developers use simulation tools to prepare for various challenges before deploying their devices.
