Computer Essentials Practice Test

IoT is about devices that have sensors or actuators and can connect to networks to share data and be controlled remotely. This broad idea fits best with the statement that the Internet of Things includes all household items that are connected to the Internet, because many common home devices—thermostats, smart TVs, refrigerators, lighting, security cameras, wearables—can be internet-connected and participate in data exchange or automation. Other descriptions miss important parts: IoT isn’t limited to industrial machines; consumer devices are a big part of IoT. IoT devices don’t have to be standalone; being connected to a network is typically what defines them as IoT. Cloud computing is helpful for many IoT deployments, but it’s not strictly required for basic functionality—devices can often operate with local processing or edge solutions.
