What is SNS?

SNS, the full name of Social Networking Services, namely social network site Service, refers to the Internet application service designed to help people establish social network site.

in p>1967, Stanley Milgram (1933-1984), a psychology professor at Harvard University, 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 is constantly enlarged and finally becomes a large network. This is Social Networking site's early understanding. Later, according to this theory, some people established social network site-oriented Internet services, which expanded social networking through "acquaintances of acquaintances", such as 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 meaning has gone far beyond the level of "acquaintances of acquaintances". For example, cohesion based on the same topic (such as posting), cohesion based on learning experience (such as Facebook), and cohesion based on the same place for weekend trips are all included in the category of "SNS".

----------------------Perfect Shi supplement. What is SNS in the first chapter?

SNS: Social Network Sofware, a social network software, based on the six-degree theory, expands one's contacts based on knowing friends. And unlimited expansion of their own contacts, when needed, you can always get a little, get the help of the contacts.

SNS is a next-generation personal-based network basic software built by using distributed technology, popularly speaking, P2P technology. Through distributed software programming, SNS arranges the CPU, hard disk and bandwidth scattered on everyone's devices as a whole, and gives these devices, which are relatively small to servers, more powerful capabilities. These abilities include: computing speed, communication speed and storage space.

social network site (Social Networking:SN): refers to the relationship network between individuals. This website based on the idea of social networking relationship system is the social network site website (SNS website). Nowadays, many WEB2. websites belong to SNS websites, such as online chat (IM), making friends, video sharing, blogs, podcasts, online communities, and music enjoyment. Social network site's theoretical basis comes from Six Degrees of Separation and Rule Of 15.

the technical origin of SNS: in the Internet, PCs and smart phones have no powerful computing and bandwidth resources, and they 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 have more powerful capabilities than those of those servers. This is the root of the birth of distributed computing theory and the theoretical basis of the birth of SNS technology.

SNS commercial space: 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 in 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 operators such as Shanda Online Games, the powerful cluster of 3, servers that they are proud of, is it their core competitiveness? When a cartoonist's home machine allows him to play his works through SNS video player, does he still need to manage a website? Perhaps a housewife doesn't need to know Html programming or the word website. 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 client, we are like idiots. We can only do slave-like things through the server, watch 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 one billion computers play their own role and let users create and control their own information. We don't need the company's servers to push us around.

SNS website: it is a website established according to the six-degree theory to help you run friends in your circle of friends.

Six-degree relationship theory: Myhrgren, a famous American social psychologist, first proposed in the 196s that in the interpersonal context, if you want to meet any strange friend, you can achieve your goal only through six friends at most. That is to say, if you want to know someone, you can ask a friend to find someone who knows him, and there will be no more than six people.

In real society, people's communication forms a circle of friends and contacts through introductions and handshakes between people. Everyone doesn't need to know everyone directly, but only through his friends and friends of friends can a handshake be promoted. Ordinary network communication is mostly realized through some platforms, such as putting yourself on a platform for many people to see and contact you to know you. The advantages and disadvantages of the two are obvious. The advantage of social communication is reliability, and their relationship is based on a reliable interpersonal network. The disadvantage is that it takes a long time and costs a lot to shake hands. The advantage of platform-based network communication is low cost, but it is not reliable.

then, copying this mechanism in the network, that is, in theory, obtains the dual advantages of reliability and low cost. There are also some advantages: in SNS, the relationship in the circle of friends is often very real and reliable, and there is no so-called "mask" of the network between them, so it is easier to realize real-name registration system; Sns is based on people-to-people contact network, with one transmission and many transmissions. With the cheap and fast platform of network, the speed of network establishment will be very fast, which further reduces the cost of establishing personal network.

to put it aside, in fact, apart from technical details, web2. is entirely up to netizens to publish content and form public opinion. In my opinion, it is not entirely feasible. If the service is informative, it's fine, but what about sensitive information? It is possible to let public opinion drift unchecked in a completely idealized democratic society, but it is not possible at present. There are many reasons for this. Moreover, netizen real-name registration system has failed to implement it at present, and the idea that everyone is not responsible for speaking online is everywhere. How to control irresponsible speech? So web2. can't be very open in the real environment.

Having said so many digressions, I just mean that SNS is an ideal means of web2. if I really want to make a speech website without the control of the webmaster. The reason is simple: SNS is closer to real-name registration system, and its online and offline identities are consistent. It can be seen that SNS is a promising thing in the future, at least in China. There is a big market gap in this respect. Since traditional media have turned to the Internet, how can we only rely on meeting, eating and making phone calls for social communication?
