The internet of things, or IoT,is a system of interrelated computing(71)，mechanical and digital machines, objects, animals or people that are provided with unique identifiers(UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
An IoT ecosystem consists of web-enabled smart devices that use(72)，such as processors,sensors and communication hardware, to collect send and act on data they acquire from their environments. IoT devices share the sensor data they collect by connecting to an IoT ga eway orother edge device where data is either sent to the cloud to be analyzed or analyzed locally.Sometimes, these devices(73)with other related devices and act on the information they get from one another. The devices do most of the work without human intervention although people can interact with the devices -for instanceto set them upgive them instructions or access the data.
The connectivity, networking and communication protocols used with these web-enabled devices largely depend on the specific IoT(74)deployed. IoT can also make use of artificial intelligence(AI)and machine learning to(75)in making data collecting processes easier and more dynamic.
