The overview outlines of a brief history and definition of the Internet of Things, along with exploring the components of the IoT: people, infrastructure, things, and data, and processes.
- [Instructor] The idea for the Internet of Things began in the early 1970s. Scientists started to see the potential for interconnected information systems, mobile agility, combined with location and energy-aware applications. At that time, scientists used the phrase pervasive computing or the embedded internet. Data scientists envisioned a computing environment where millions of computers are integrated into everything we use and communicate with another.
The idea is that technology blends so gracefully within our world that it essentially disappears. In 1999, Kevin Ashton was working with an advanced technology called radio frequency identification, which are small tags that someone can place in an object, such as animals or merchandise in a store, and track that object. He saw the potential use of RFID and coined the phrase the Internet of Things, which represents the concept of a massive system where things on the internet communicate through ever-present sensors.
A catchy phrase, however, the term Internet of Things didn't really get a foothold until almost a decade later. Soon after 2010, industry leaders began taking a good, hard look at the Internet of Things as a new, emerging wonder that would ultimately translate into a billion dollar market. In 2014, manufacturers started to produce and mass market intelligent devices embedded in everyday objects that connect to the internet, enabling them to send and receive data.
The Internet of Things has several components: people, infrastructure, things, processes, and data. People are what drives the Internet of Things. Infrastructure is the internet backbone and things, such as thermostats, wearable fitness, home automation, and cameras, to name a few, and data that is collected and sent to other devices, from humans to machine, from machine to machine, or machine to humans.
Processes, which manage the way people, infrastructure, things, and data all work together. Today, the world is only beginning to see the value and potential impact of the Internet of Things in our everyday lives. Within a few years, expect a massive transition to the Internet of Things. By 2020, industry estimates 50 billion devices, which means a future where everyday things all interconnect with a goal of improving the overall quality of life.
Lisa Bock kicks off the course with an overview of IoT, and the types of IoT devices designed to improve the quality of life in homes and businesses. Lisa covers different networks that range in size and purpose—LANS, WANS and PANS—and explains how businesses invest heavily in IoT in order to keep a competitive edge, going into IoT developments in automobiles, building automation, and the medical field. She then evaluates consumer devices, such as wearables and mobile devices. Plus, she discusses zero-configuration networking, service discovery, designing IoT security, and more.
