what are the four primary systems of iot technology?

The four essential frameworks of IoT (Web of Things) innovation are:

1. **Device (Sensor/Actuator) Layer**:

- **Devices**: These are the actual articles furnished with sensors and actuators. Sensors gather information from the climate (e.g., temperature, dampness, light, movement), while actuators can perform activities in view of gotten orders (e.g., turning on a light, changing an indoor regulator).

- **Examples**: Savvy indoor regulators, wellness trackers, natural sensors.

2. **Connectivity Layer**:

- **Organization and Correspondence Protocols**: This layer gives the means to IoT gadgets to associate and speak with one another and with focal frameworks. Different correspondence advancements and conventions are utilized, including Wi-Fi, Bluetooth, Zigbee, LoRa, NB-IoT, and cell organizations.

- **Examples**: Wi-Fi for home mechanization gadgets, Zigbee for savvy lighting frameworks, LoRa for long-range agrarian observing.

3. **Data Handling Layer**:

- **Edge Computing**: Handling information close to the information source to lessen dormancy and data transmission use. This includes performing calculations and going with choices locally at the edge gadgets.

- **Cloud Computing**: Unified information capacity and handling abilities, taking into account progressed investigation, AI, and enormous scope information the executives.

- **Examples**: Edge passages for constant handling in modern IoT, cloud stages like AWS IoT, Microsoft Sky blue IoT Center for enormous scope information examination.

4. **Application Layer**:

- **UIs and Applications**: This is the connection point through which clients associate with the IoT framework. It incorporates dashboards, portable applications, web interfaces, and other programming that permit clients to screen, control, and oversee IoT gadgets and frameworks.

- **Examples**: Savvy home applications for controlling lighting and security frameworks, modern IoT dashboards for checking hardware and cycles, medical care applications for following patient wellbeing information.

These four frameworks cooperate to shape a far reaching IoT environment, empowering consistent coordination of actual gadgets with computerized networks, information handling capacities, and client applications.
