The architecture of IoT consists of different layers including which of the following? i. Application Layer ii. Sensing Layer iii. Combination Layer iv. Network Layer

The correct answer is: A. i, ii, iv

The architecture of IoT consists of four layers:

• Application Layer: This layer is responsible for the interaction between the user and the IoT system. It provides the user with a way to control the IoT devices and to view the data that they collect.
• Network Layer: This layer is responsible for the communication between the IoT devices and the cloud. It provides the necessary infrastructure for the devices to send and receive data.
• Sensing Layer: This layer is responsible for the collection of data from the physical world. It includes the sensors that are used to collect data from the environment, such as temperature, humidity, and light.
• Device Layer: This layer is responsible for the management of the IoT devices. It includes the software that is used to control the devices and to collect data from them.

The combination layer is not a separate layer in the IoT architecture. It is a term that is sometimes used to refer to the interaction between the different layers of the architecture.

The sensing layer is responsible for collecting data from the physical world. This data is then sent to the network layer, which is responsible for transmitting it to the cloud. The cloud is responsible for storing and processing the data, and for providing it to the application layer. The application layer is responsible for providing the user with a way to interact with the IoT system.
