What is the difference between the Internet of Things and the Internet

The Internet of Things and the Internet differ in three main ways:

1. The coverage of the Internet of Things is much larger than that of the Internet. The Internet was created for the purpose of exchanging information through the network, and the main body of its services is people. The Internet of Things is born for things, mainly for the management of things, so that things can exchange information autonomously, and indirectly serve human beings.

2. Internet users access Internet resources and send or receive e-mails through servers, desktops, laptops and mobile terminals of the end system; blogging or reading blogs; communicate via the network**; Buy and sell ** online, book air tickets and hotels. The sensor nodes in the Internet of Things need to be connected to the Internet through the aggregation nodes of the wireless sensor network.

3. The Internet of Things involves a wider range of technologies. The technologies used in the Internet of Things mainly include wireless technology, Internet, smart chip technology, and software technology, covering almost all fields of information and communication technology. And the Internet is only one technical direction of the Internet of Things.

The Internet can only be a virtual communication, while the Internet of Things realizes the communication between physical objects.

1.The Internet of Things, as the name suggests, is the networking of things between things. To put it simply, it is composed of four links: item information identification, perception, processing, and transmission, and uses the network resources of the Internet (including wireless communication networks) to transmit business information.

2.In fact, the Internet is a system that uses communication equipment and lines to interconnect multiple computer systems with different geographical locations and independent functions, and realizes resource sharing and information transmission in the network with perfect network software (i.e., network communication protocols, information exchange methods, network operating systems, etc.).

1。The Internet of Things is an important part of the new generation of information technology. The English name of the Internet of Things is "the Internet of Things".

As the name suggests, the Internet of Things is the "Internet of Things". This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network on the basis of the Internet;

2。Its user terminal extends and extends to any object to object for information exchange and communication. Therefore, the definition of the Internet of Things is:

Through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing equipment, according to the agreed agreement, any object is connected to the Internet for information exchange and communication, so as to realize the intelligent identification, positioning, tracking, monitoring and management of the object.

The Internet of Things is by no means an infinite extension of a simple global shared internet. Even though the Internet does not only refer to what we commonly think of as an international shared computer network, the Internet also has a wide area network and a local area network. The Internet of Things can be an extension of the Internet to things in our usual sense; It can also form a local area network and a professional network according to practical needs and industrial applications.

In reality, it is not necessary or possible to network everything; There is no need to make professional networks and local area networks all have to be connected to the global Internet sharing platform. In the future, the Internet of Things will be very different from the Internet, similar to Zhishi Hehui logistics, intelligent transportation, smart grid and other professional networks; Local area networks such as intelligent communities are the largest application space.

The Internet, that is, the international computer network composed of wide area network, local area network and single machine according to a certain communication protocol. The Internet refers to the result of linking two computers or more than two liters of computer terminals, clients, and servers through the means of computer information technology, so that people can send emails to each other, complete a job together, and have fun together with friends who are thousands of miles away.

The Internet of Things is defined as the real-time collection of any object or process that needs to be monitored, connected and interacted with through various information sensing devices, such as sensors, radio frequency identification (RFID) technology, global positioning systems, infrared sensors, laser scanners, gas sensors and other devices and technologies, and collects various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., which is combined with the Internet to form a huge network. Its purpose is to realize the connection between things and things, things and people, and all items and networks, so as to facilitate identification, management and control.

This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network on the basis of the Internet; Second, its user terminal extends and expands to any object to object for information exchange and communication.

The earliest is the fixed mutual backup and destruction network, and it is impossible to enter the network without the connection line. Later, with the development of mobile communications, the mobile Internet appeared. But whether it's mobile or fixed, the Internet is all about connecting people.

The third generation of the Internet is the connection of people and things, at this time, we call the Internet of Things, in China called the sensor network.

Summary. For users, there is really not much difference between the Internet and the Internet of Things, and the biggest difference is that the content and services provided by the Internet of Things are different from the Internet.

If I'm an IoT user, I just need to know what information my IoT has (lights on at home, computers in the office turned off) and what I can do (turn off the lights and turn on computers in the office). This is the content and services that the Internet of Things has given me.

The difference and connection between the Internet of Things and the Internet.

For users, there is really not much difference between the Internet and the Internet of Things, and the biggest difference is that the content and services provided by the Internet of Things are different from the Internet. For example, I can watch the news on Weibo, chat with friends on WeChat, and ask questions about Zhihu. That's what the internet offers me and what it does.

If I'm an IoT user, I just need to know what information my IoT has (lights on at home, computers in the office turned off) and what I can do (turn off the lights and turn on computers in the office). This is the content and services that the Internet of Things has given me.

From a technical point of view, the Internet of Things and the Internet are too different! After decades of development of the Internet, until now there is very little talk about the Internet as a technology, and only occasionally I hear that a certain technology belongs to the Internet technology. As far as the Internet is concerned, we usually say that web development technology, search engine technology, online game technology, mobile development technology, and live broadcast technology belong to Internet technology.

Internet technology composition example, to be added) Internet of Things technology, is the integration of electronics, communications, computer technology in the three major fields of technology, on the basis of the Internet to achieve the connection of things. From the technical level, the Internet of Things has four levels: perception and recognition layer, network construction layer, service management layer, and comprehensive application layer.

In fact, it is the Internet industry + financial industry that does Internet finance, the Internet + entertainment that does online games, the Internet + traditional sales industry that does e-commerce, and the Internet + traditional education that does Internet education, so it is very simple to do the Internet of Things, which is Internet + electronic power equipment.
