Study Notes

Introduction to IoT

IoT (Internet of Things) connects sensors and actuators over the internet, adding value to interconnected devices.
Often referred to as a “System of Systems.”

History of IoT Development

Concepts of devices with embedded intelligence emerged in the 1970s with microprocessors and microcontrollers.
The first connected embedded system, a modified Coca-Cola vending machine, appeared in 1989 at Carnegie Mellon University.
RFID technology and cellular networks drove IoT advancements in the early 2000s, addressing power and communication challenges.
Kevin Ashton coined the term "Internet of Things" in 1999, evolving the internet from People-to-People to Machine-to-Machine communication.
Low-cost embedded processors and mobile data networks fueled IoT adoption in consumer markets in the 2010s.

Terms related to IoT include Internet of Everything (IoE) by Cisco, "embedded internet" by Intel, M2M (Machine to Machine) communication, Web of Things, Industry 4.0, Smart systems, Ubiquitous computing, and Intelligent systems.
