However, just like every trending phrases like this, a good number of people are curious about what the IoT entails. Therefore, they ask, “What is this, and what are its uses in our world today?”

That’s why this article is right here. This article seeks to give answers to the above questions. Here, we will be discussing the Internet of Things, different IoT applications, its impacts in different industries and how they are applying it, the trends and future of IoT.

What Is the Internet of Things?

We will start with the basics. There are several definitions of IoT out there. Most time, the definition is usually based on the perspective of author. Here, we will be giving you a straightforward and simple definition. IoT is simply a network of devices and appliances that are connected via the internet. These devices can collect and transmit data without human interaction.

Simply say, the Internet of Things describes the connection of devices to each other and to humans via the internet. IoT can offer relevant data about its operation and that of an activity. These days, several companies from various sectors are integrating this technology.

IoT devices get data and send through some central data server. The data is then processed, distilled, and utilize in making certain tasks easier to perform. When these devices are internet-connected, they  obtain and share data and then make decisions via  Neural Networks and Machine Learning (complex mechanisms).

Devices which are IoT-equipped are refrigerators, laptops, Applewatches, smartphones, coffee machines, Google Home, Fitbits, and many more. Any device that has internet connection and sensors  can be plugged into the IoT.  There are several devices connected across the globe right now. These devices are busy gathering billions of petabytes of data every day.

Most times, IoT is seen as Big Data, since IoT collects the same kind of massive quantities of data characteristic of Big Data. Therefore, all the data from the Internet of Things is Big Data. However, not all information of Big Data is from the IoT.

The government, private organizations and individuals all enjoy the benefits of IoT.

What are IoT Applications?

IoT serve several functions in different aspects of life. These technologies have been adopted in a wide range of industries. You will find then in both government and privately-owned sectors.
