CONNECTING THE DOTS

2. HOW DOES IOT WORK?
Many people think that the working of IoT is hard, but it is actually not. Don’t
mistake me for talking about the coding part, which is genuinely challenging.
However, the theory and understanding are pretty simple.
IoT in itself consists of 4 main components that make its working possible. Let us
first look at each of these 4 components in depth, and then you can picturise how
IoT will work. The 4 essential components for the working of IoT are:
1. Sensors and actuators
2. Connectivity
3. Data processing
4. User interface

3. A CUMULATIVE RECAP OF
HOW IOT WORKS
Now that you know the role of each of the 4 components and have a rough idea of
how they work together for an IoT system to function, let us look at the holistic
picture to understand the working of IoT.
So we saw that the sensors collect various information, which needs to be sent to
the cloud for processing. But for the sensors to communicate or send data to the
cloud, they need a protocol, AKA connectivity. It is also this connection that lets the
other devices communicate with each other and work coherently.
Once we have the connection or protocol, the sensors send the analyzing data to
the cloud for processing this data into a digital form. Why should the data be
converted to a digital form? Well, the data needs to be converted to digital form so
that machines can understand and perform tasks based on it.

4. SUMMARY
As you have seen, 4 components that work coherently together for the working
of IoT. They cannot exist without each other. You have now learned how IoT
works as we dived deep into the 4 components and discussed their roles in the
working of IoT.
