The Internet of Things (IoT) represents billions of devices collecting and exchanging data. Learn what comprises the IoT: people, infrastructure, and things.
- [Narrator] Today, there are many places and ways that we use the Internet of Things. Places include our homes, cars, cities, buildings, and hospitals. Some of the ways we use the Internet of Things include our watches connecting to fintech, cars talking to the toll booth, and buildings automatically adjusting the temperature. The IOT has already achieved substantial growth, however, 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. Scientists coined the phrase pervasive computing, or the embedded internet. They envisioned a computing environment where millions of computers would be integrated into everything we use, and would talk to us and to each other. The idea is that technology blends so gracefully within our world, that it essentially disappears. Fast forward to 1999. Kevin Ashton, a technology pioneer, was working with an advanced technology called radio frequency identification. RFID tags are small and you can place these tags in an object, such as animals or merchandise in a store, and then track that object. He saw the potential use of RFID and coined the phrase Internet of Things, which represents a 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 to take 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 into 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. Things are things such as thermostats, wearable fitness, home automation, and cameras. And data that is collected and sent to other devices, from humans to machine, from machine to machine, or machine to humans. And processes 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. By 2026, industry experts predict a market size of more than a trillion dollars. This 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.
