Introduction to the Internet of Things and Embedded Systems Quiz Answers

About Introduction to the Internet of Things and Embedded Systems Course

The explosive growth of the “Internet of Things” is changing our world and the rapid drop in price for typical IoT components is allowing people to innovate new designs and products at home. In this first class in the specialization, you will learn the importance of IoT in society, the current components of typical IoT devices, and trends for the future.

IoT design considerations, constraints, and interfacing between the physical world and your device will also be covered. You will also learn how to make design trade-offs between hardware and software. We’ll also cover key components of networking to ensure that students understand how to connect their devices to the Internet. Please note that this course does not include discussion forums.
