After the birth of the bet365 promo codes in 1969，The formulation of two important standards, TCP/IP and World Wide Web，Powerfully promoted the global development of information technology and the prosperity of the technological ecosystem。Since the 21st century，With the explosion of cutting-edge technology and the rise of brain-like intelligent giant systems，Human society is facing the formulation of the third global standard for information technology ecology。

1974: The first global standard for information technology ecology。At the beginning of the bet365 promo codes，Most computers connected to the bet365 promo codes are not compatible with each other。Work done on one computer，It’s hard to get another computer to use。1974，American scientists Robert Elliot Kahn and Vint Cerf jointly developed the TCP/IP protocol，This protocol specifies an access address for every device running on the bet365 promo codes，Different computers at the same time，There are even unified standards for transmitting packets between different types of networks。All computers connected to the network，As long as they comply with these two agreements，are able to communicate and interact。The emergence of TCP/IP is also a sensor after the 21st century、Robot、Drone、Smoothing of smart cars and other smart devices、Laying the foundation for barrier-free access to the bet365 promo codes，for the bet365 promo codes of Things、Edge computing、Cloud Robot、The emergence of the industrial bet365 promo codes provides technical support。

1989: The second global standard for information technology ecology。1980s，After nearly 10 years of development，The bet365 promo codes has grown into world technology、Military、A huge network of information sharing among government agencies，But due to technical architecture problems，The information on the bet365 promo codes is like being locked in boxes，Requires password and key to obtain，The information between boxes cannot be obtained from each other。1989，Tim Berners-Lee, a physicist working at the European Nuclear Physics Laboratory, chose Hypertext Markup Language (HTML) as the key to realizing information sharing on the bet365 promo codes。When information on the bet365 promo codes is written in a hypertext format that links to each other，You can reference and share information with other servers。Meanwhile，Berners-Lee created the world's first Web server。All updated information is only modified on the web server，Tens of millions of other client computers retain no or very little information，More information and data required by accessing the server，This structure is also often called the B/S structure of the bet365 promo codes。The formulation of World Wide Web standards has had a huge impact on the subsequent technological ecology，Including cloud computing that emerged in the 21st century、Big data, etc. are all related to the World Wide Web，Even the emergence of blockchain can be said to be to a certain extent to combat the trend of bet365 promo codes centralization caused by the World Wide Web。

After 2010: The third generation of demand for global standards for information technology ecology。Since the 21st century，Explosive growth in cutting-edge technology，A large number of new technologies and concepts have emerged，From social networks、Cloud computing、bet365 promo codes of Things、3G、Big data, etc.，To artificial intelligence、5G、Cloud Robot、Edge computing、Digital twin, etc.。There are various signs that，The bet365 promo codes architecture has undergone major changes，Evolving from reticular structure to brain model，The element of connection also extends from computers to people、Intelligent machines and AI systems。After 2010，Changes in the bet365 promo codes architecture have led to the continuous emergence of various technological brain systems。Among them，City Brain acquires government agency、Key concerns of the technology industry，For example, hundreds of cities in my country have launched the planning and construction of urban brains。Currently，Whether it is the bet365 promo codes of Things、Social Network、Intelligent driving or city brain，More efforts need to be made in the construction of industry brain，Just people、Connect machines and systems together without any barriers。Same as the problems faced by the previous two global standards for technological ecology，Because the elements of the new bet365 promo codes connection are fragmented，Objective need for a unified global standard for people around the world、Standardize information interaction between machines and systems，Thus realizing its response and processing to the needs of human society as a whole。

It should be said，City Brain is the product of the formation of the bet365 promo codes brain model and its integration with smart city construction，It is a subset of the bet365 promo codes brain architecture，Also an important part，When the urban brains of various countries mature and become connected，The world-wide urban brain will eventually form a world nervous system (world brain) framework based on the bet365 promo codes brain model。How to formulate operating rules for the nervous system of this world，It is not just the construction standards of urban brains that need to be solved，What’s more important is the global standard for the third information technology ecology。The emergence of this standard will promote various cutting-edge technologies to form a unified whole，Provide support for the coordinated development of mankind，Toward the intelligent industry、Urban Construction、Making an important impact in the fields of science and technology and economy。
