About This Course


The Internet of Things (IoT) is a term that refers to the use of the internet to connect numerous physical devices and objects all over the world. Kevin Ashton coined the term “internet of things” in 1999. The next section explains the fundamentals of IoT. It covers the various levels utilized in IoT as well as some key concepts. It is essentially an expansion of the Internet’s offerings. The architecture of the Internet of Things is also presented in this section. When our everyday household equipment link to the internet, for example, the system is referred to as a Smart-Home in an IoT context. The Internet of Things is more than a futuristic concept. It’s already in place, and it’s having an impact on more than simply technological progress.


The Internet of Things (IoT) is a network of physical objects such as devices, instruments, vehicles, buildings, and other items that are equipped with electronics, circuits, software, sensors, and network connectivity to gather and share data. The Internet of Things enables items to be sensed and controlled from afar using existing network infrastructure, allowing for more direct integration of the physical world into computer-based systems and better efficiency and accuracy.

The idea of a network of smart devices was originally explored in 1982, when a modified Coke machine at Carnegie Mellon University became the first internet-connected appliance [3], reporting inventory and whether newly filled beverages were cold. Kevin Ashton (born 1968) is a British technology pioneer who coined the term “Internet of Things” to describe a system in which the Internet is linked to the physical world through omnipresent sensors.

IoT can communicate without the need for human interaction. In the healthcare, transportation, and automotive industries, some experimental IoT applications have already been developed. Although IoT technologies are still in their infancy, several new advancements in the integration of items with sensors on the Internet have occurred. Infrastructure, communications, interfaces, protocols, and standards are all part of the IoT development process.

The goal of this article is to provide an overview of the Internet of Things, including its architecture and levels, as well as some key words and services.


In 1999, Kevin Ashton introduced the Internet of Things (IoT), which he defined as “uniquely identifiable connected things using radio-frequency identification (RFID) technology.” However, the precise definition of IoT is still being developed and is dependent on the viewpoints chosen. “Dynamic global network infrastructure with self-configuring capabilities based on standards and communication protocols” was the general definition of the Internet of Things.
