Internet of Things (IoT): Cheat sheet – TechRepublic
The Internet of Things, which is commonly called IoT, refers to the billions of devices around the world that are connected to the internet through sensors or Wi-Fi. It’s basically a giant network of objects that connect to the internet. Each device collects data, and this data, known collectively as big data, is exchanged and analyzed.
IoT-connected smart devices can be an everyday item such as a phone, car, watch, washing machine, or refrigerator. IoT devices can also be components of machines and systems, such as on an oil rig or airplane engine.
As costs go down, IoT is more accessible than ever. Gartner estimates that about 8.4 billion IoT devices were in use in 2017, up 31% from the previous year, and it will hit 20.4 billion by 2020. Total world spending on IoT hit about $2 trillion in 2017.
