Abstract
Hello and welcome to the introductory module of the IoT and Security course. IoT stands for Internet of Things and is a concept that has received a lot of attention in the past few years. The term IoT basically means a technology that allows communication between devices over the internet. Also between devices and humans over the internet or network. These devices can include sensors, microcontrollers and actuators. Some are smart devices and others are not. Smart devices are those that do some bit of processing before conveying information across to other devices or to humans.

Hello and welcome to the introductory module of the IoT and Security course. IoT stands for Internet of Things and is a concept that has received a lot of attention in the past few years. The term IoT basically means a technology that allows communication between devices over the internet. Also between devices and humans over the internet or network. These devices can include sensors, microcontrollers and actuators. Some are smart devices and others are not. Smart devices are those that do some bit of processing before conveying information across to other devices or to humans.
In this module, we will start by learning about the architecture of IoT; basically how devices may be organized for the purpose of interacting with each other and with humans, the hardware and software components involved, the different abstraction layers of an IoT architecture.
After introducing the IoT architecture, we will then learn about the different components in IoT, or the “Things” in IoT. There are smart components and non-smart components. We will learn about their communication capabilities, naming and addressing these components - because they interact with each other and therefore there is a need to uniquely address them, their processing power and their capabilities.
