What is the Internet of Things?

Let’s begin with the basics. Exactly what is the Internet of Things? There are plenty of definitions out there, and a lot of time, it depends on the perspective of the article’s author. The simplest, most straightforward definition is: The IoT is a network of Internet-linked devices, vehicles, and appliances that can collect and share data without need of human interaction. That’s it.

IoT devices gather information and send it along to some central data server, where the information is processed, collated, distilled, and used to make a host of tasks easier to perform. The business world enjoys the benefits of IoT, government, organizations, and the individual consumer.

Specific IoT-equipped devices include smartphones, laptops, coffee machines, refrigerators (mine auto-orders replacement water filters!), Google Home, Apple watches, Fitbits, to name a few. Any device can be plugged into the IoT provided it is equipped with sensors and an Internet connection.

Often, IoT is mentioned in the same breath as Big Data, since the former generates the kind of massive quantities of information characteristic of the latter. One could say that while all of the information from the Internet of Things is Big Data, not all of Big Data is from the Internet of Things.

What Are the Internet of Things Applications?

The Internet of Things can be used in many different aspects of life, in both the private and public sectors. Thanks to IoT, people can track things like lost pets, their house’s security systems, or appliance maintenance schedule.

Consumers can use the IoT to help them make restaurant reservations, monitor their exercise progress and overall health, and receive coupons for a store only by virtue of walking by the business in question.

Businesses can use IoT to monitor supply chains, track customers’ spending habits as well collect their feedback, monitor and maintain inventory levels, and engage in predictive maintenance of their machines and devices.

The IoT also proves helpful in ITIL, which is a set of IT service management, an important detail, since IT departments are called on to do more and more in a world that’s getting increasingly digital, with more reliance on wireless networks.

Blockchain, which is being increasingly used as a more efficient and secure method of transaction and data processing, is a natural beneficiary of IoT technology. We can expect to see IoT and Blockchain coming together more often in the future.

But how do different industries apply the Internet of Things to make things more efficient?
