the internet of things is the Internet of things(IoT).
as the name implies, the internet of things is the internet where things are connected. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extension and expansion network based on the Internet; Secondly, its client extends and extends to any object and carries out information exchange and communication, that is, the information between objects. The Internet of Things is widely used in network convergence through communication sensing technologies such as intelligent perception, identification technology and pervasive computing, so it is called the third wave of world information industry development after computers and the Internet. The Internet of Things is the application expansion of the Internet. It is not so much a network as a business and application. Therefore, application innovation is the core of the development of the Internet of Things, and innovation 2. with user experience as the core is the soul of the development of the Internet of Things.
If it is applied, it includes the Internet of Vehicles, smart home, smart agriculture, smart city, etc.
Smart city is to use information and communication technology to sense, analyze and integrate the key information of urban operation core system, so as to make intelligent responses to various needs including people's livelihood, environmental protection, public safety, urban services and industrial and commercial activities. Its essence is to use advanced information technology to realize the intelligent management and operation of the city, thus creating a better life for people in the city and promoting the harmonious and sustainable growth of the city. With the continuous development of human society, cities in the future will carry more and more people. At present, China is in a period of accelerated urbanization, and the problem of "urban disease" in some areas is becoming increasingly serious. In order to solve the problem of urban development and realize the sustainable development of cities, building smart cities has become an irreversible historical trend of urban development in the world today.
the construction of smart cities has been carried out in many areas at home and abroad, and a series of achievements have been made, such as smart Shanghai and smart Shuangliu in China; Abroad, such as Singapore's "Smart Country Plan" and South Korea's "U-City Plan".
quantum communication refers to a new communication method that uses quantum entanglement effect to transmit information. Quantum communication is a new interdisciplinary subject developed in recent twenty years, and it is a new research field combining quantum theory with information technology. Quantum communication mainly involves: quantum cryptographic communication, quantum teleportation and quantum dense coding, etc. Recently, this subject has gradually moved from theory to experiment and developed into practicality, which has become the research focus of quantum physics and information science in the world.
The application of quantum communication is like the quantum encrypted transmission of remote data in online banking.
Self-media refers to the way that ordinary people publish their own facts and news through the Internet and other channels. "From the media", English is "We Media". It is a way for ordinary people to provide and share their own facts and news after they are connected with the global knowledge system through digital technology. It is a private, civilian, generalized and autonomous disseminator, and it is the floorboard of new media that delivers normative and non-normative information to an unspecified majority or a specific individual by modern and electronic means.
There are too many self-media applications, such as Weibo and WeChat official account.
