The Internet of Things (IoT) is impacting human lives in a myriad of ways. It refers to a broad network of interconnected devices, with unique identifiers that can communicate and transfer data over a network without requiring any human interaction. The major function performed by IoT is gathering and transmitting data, but it is not limited to this.


Many devices can even process data. IoT makes use of many technologies like application programming interfaces (APIs),  Big data management tools,  Artificial Intelligence (AI) and machine learning, predictive analysis, radio-frequency identification, and the cloud.  Some of the common IoT technology devices are energy meters, mobile devices, and smart appliances.

While analyzing the IoT statistics, it is pertinent to note that the figures vary widely across different research bodies and companies.  Still, there is a general trend that the varying data arrives at, which can be used to analyze the IoT segment.

What are the growth statistics of IoT?


The internet market is growing at a fast pace. By 2020, the consumer and business spending on IoT devices is expected to reach $3 trillion.
