1967, Stanley milgram, a professor of psychology at Harvard University (1934 ~ 1984) founded the theory of six-degree division, which simply said: "There will be no more than six people between you and any stranger, that is, you can know any stranger through six people at most." According to the six-degree separation theory, each individual's social circle continues to expand and eventually becomes a big network. This is the early understanding of social networking sites. Later, according to this theory, some people established Internet services for social networking sites, and expanded their social networks through "acquaintances of acquaintances", such as ArtComb, Friendster, Wallop, adoreme, etc.
But "acquaintances of acquaintances" is only a way of social expansion, not the whole of social expansion. Therefore, now the so-called SNS, its significance has gone far beyond the "acquaintances of acquaintances" level. For example, cohesion based on the same topic (such as posting), cohesion based on learning experience (such as Facebook) and cohesion based on weekend travel in the same place all belong to the category of "SNS".
SNS comes from English abbreviations.
Social network has three meanings of SNS in the Internet field: service social network service, software social network software and website social network site. Chinese literal translation of social networking service is social networking service or social networking service, and free translation is social networking service. The network meaning of Chinese includes hardware, software, service and website application, and the four-word phrase is more in line with the Chinese word-formation habit, so people are used to referring to SNS (including social network service), social network software and social networking site. SNS refers to Internet application service, which aims to help people build social networking sites.

[Edit this paragraph] Chapter 1 What is SNS?
SNS: social networking software, social networking software, based on the six-degree theory, to make friends with friends and expand contacts. And unlimited expansion of their contacts, when needed, you can always get a little, get the help of contacts.
SNS is the next generation of personal-based network basic software using distributed technology, which is popularly called P2P technology. Through distributed software programming, SNS arranges the CPU, hard disk and bandwidth scattered on everyone's devices as a whole, giving these devices, which are smaller than servers, more powerful capabilities. These capabilities include computing speed, communication speed and storage space.
Social networking (SN): refers to the relationship network between individuals. This website based on the idea of social network relationship system is social networking website (SNS website). Nowadays, many WEB2.0 websites belong to SNS websites, such as online chat (IM), making friends, video sharing, blogs, podcasts, online communities, music sharing and so on. The theoretical basis of social networking sites comes from six degrees of separation and 150 rule. In addition, not only some websites of large companies have started some SNS applications, but also some websites of vertical industries have begun to try SNS, and the effect is good. For example, Honeycomb (b.com) is an SNS website dedicated to visual artists, and social games () is a social game promotion platform based on the open platform of Manyou.
The technical origin of SNS: In the Internet, PCs and smart phones have no powerful computing and bandwidth resources, and rely on website servers to browse and publish information. If the computing and bandwidth resources of each device are redistributed and shared, these devices may be more capable than those servers. This is the root of the birth of distributed computing theory and the theoretical basis of the birth of SNS technology.
The commercial space of SNS: When ordinary people can have computing and communication resources comparable to website servers by installing SNS software, what will those Internet companies that have invested a lot of servers do? What are their advantages? Will there be more new internet companies, and is it possible that their backstage and front-end are completely different from the current Google, EBAY and Sina models? Even for operators like Shanda Online Games, is the powerful cluster of 30,000 servers that they are proud of their core competitiveness? Does a cartoonist need to manage a website when his home machine allows him to play his works through SNS video player? Maybe a housewife doesn't need to know Html programming or word websites. Millions of people can master her craft only through SNS recipe publishing program and a PC in the kitchen, and her every move and style on the kitchen stove can be clearly seen. What do you think of at this time? In today's internet, as a customer, we are like idiots. We can only do slave-like things through the server, look at other people's websites, play other people's games and send emails. Besides, we have no freedom. Now is the time to start the revolution! The task of the revolution center is: how to make more than 654.38+0 billion computers play their role and let users create and control their own information. We don't need company servers to push us around.
SNS website: It is a website established according to the six-degree theory to help you manage your friends in your circle of friends.
Six-degree relationship theory: Myhrgren, a famous American social psychologist, proposed for the first time in 1960s that if you want to meet any strange friends in the context of interpersonal communication, you only need six friends at most to achieve your goal. In other words, if you want to know someone, you can ask your friends to find people who know him, not more than six people.
