What Is Internet Of Things – Introduction To Internet Of Things

The Internet of things (IoT) is a system of interconnection of physical devices like electronic machines, vehicles, home appliances, and other items. These items are embedded with electronics, software, sensors, and other connectivity, which enable in connection and sharing of data. This network of a physical object is accessible through the Internet and content-embedded technology that interact with the internal and external environment.

History Of The Internet Of Things

The concept of connecting devices, especially electronic devices, has been around for a long time since the first electric telegraphs were developed in the late 1830s. One of the popular entrepreneurs Kevin Ashton, founder of the Auto-ID center at MIT, was the person who coined the term Internet of Things for the first time. He gave this name when he was working with the team who discovered the method of linking the object through the RIED tag. This phrase was issued in 1999 during the presentation, and it has become popular worldwide. 

Though Ashton gave the name but the technologies that made IoT possible are WiFi technology, radio voice transmission, and Supervisor Control and Data Acquisition (SCDA) way before they used RERD., In 1982, the students of Carnegie Mellon University made the first modified coke machine, considered the first connected smart appliance. They used local Ethernet and ARPANET to monitor the stocks of drinks and to measure the temperature.

By now, we can see lots of IoT-connected devices around us that are more in number than human beings. Everything is connected and operated remotely, from big machinery used in manufacturing industries to wearable items like smartwatches. These devices are now using cloud-based platforms that are connected to IoT.

How the Internet Of Things Works, And What Does The Internet Of Things (IoT) Enable?

Introduction to Internet of Things has made our life easier than before, and collecting data has become super easy. But have you ever thought about how these data are collected through IoT? If not, then don’t be embarrassed, as we have mentioned detailed information about the working of IoT.

Data is first collected from the resources with the help of sensors embedded in them. These data are transferred to the cloud-based database with the help of WiFi or the Internet. Data is again collected for processing, where every factor is analyzed and provides the appropriate outcome. After processing the data and obtaining the outcome, the final results are sent to the user interface. 

The same procedure works in the telecom sectors and the internet service providers. Now the whole world is immersed in the 4G network, and it gives enough speed to enjoy the stuff. And the 5G network will be ten times the speed of LITE networks. 

But have you imagined how does 5G technology impacts the Internet of things

This will come true by increasing the bandwidth by a huge amount and connecting a large number of devices together.
