Internet (English: internet), also known as the Internet, or the Internet, the Internet, the Internet began in 1969 in the United States. It is a huge network that is connected in series between the network and the network. These networks are connected by a common set of protocols to form a logical single large international network. Usually the Internet refers to the Internet, while the Internet refers to the Internet. This method of interconnecting computer networks can be called "network interconnection". On this basis, a global Internet that covers the whole world is called the Internet, that is, a network structure that is connected to each other. The Internet is not the same as the World Wide Web. The World Wide Web is just a global system based on hyperlinks and is one of the services that the Internet can provide.

Internet: People want to know something about the Internet. Someone needs to collect this information and upload it to the Internet for people to browse. People need to do a lot of work in it, and it is difficult to dynamically understand the changes.

Internet of Things: The Internet of Things is an extension of the Internet. Through various sensing devices, such as radio frequency identification, sensors, infrared, etc., information is transmitted to the receiver, and then transmitted through the Internet. Information processing is performed through high-level applications to achieve remote monitoring and automatic Alarm, control, diagnosis and maintenance to achieve the integration of “management, control and operation”.
