How does IoT work?

Internet of Things is a combination of smart electronic devices, local area networks, the Internet, cloud servers,
and the user application. An IoT device connects through a local network. Then, it transmits information through
the Internet to the cloud servers. Further, the cloud servers provide the data or information of the end-user
application to the IoT device. This transfer of information is a two-way communication that helps operate the IoT
system.
An IoT system consists of four major components as shown in the below image:

• IoT Devices: They are smart electronic gadgets that consist of wireless sensors that help in transferring data
over the Internet.
• Local Network: It helps in accessing the data from the devices connected to the Internet.
• The Internet: It helps the devices connect with the user applications and servers.
• Back-end Services: They consist of a remote server, user access and control, and mobile applications. These
services constantly help in exchanging streamed data from various IoT devices and end-user applications.
