What does www mean?

The World Wide Web (also known as Web, WWW, W3, English Web or World Wide Web) is a data space. In this space: useful things are called "resources"; And is identified by a global uniform resource identifier (URL). These resources are transmitted to users through hypertext transfer protocol, and the latter obtains resources by clicking on links. From another point of view, the World Wide Web is a system that accesses tidal documents through the network. World Wide Web Consortium (W3C), also known as W3C Committee. 1994 10 was established in the computer science laboratory of Massachusetts Institute of Technology (MIT) with the title of "the best university in the world". The founders are Tim and Berners-Lee, the inventors of the World Wide Web. The World Wide Web is usually regarded as a synonym for the Internet, but in fact it is a service running on the Internet. [Edit this paragraph] How does it work When you want to visit a web page or other network resources on the World Wide Web, you usually need to type the uniform resource locator of the web page you want to visit in your browser or link to that web page or network resource through a hyperlink. After that, the server name part of the URL is first analyzed by the internet database called domain name system distributed all over the world, and which IP address to enter is determined according to the analysis results. The next step is to send an HTTP request to the server working at the IP address to access the web page. In general, the HTML text, pictures and all other files that make up a web page will be requested one by one and sent back to the user soon. The next job of the web browser is to show users the content described in HTML, CSS and other received files, plus images, links and other necessary resources. These constitute the "web page" you see. [Edit this paragraph] The earliest network concept of 200px-First_Web_Server.jpg can be traced back to 1980 Tim Berners-Li Jianzao's remote inquiry project. This is a hypertext online editing database similar to Wikipedia. Although this is very different from the World Wide Web we use now, they share many of the same core ideas, even including some ideas of the next project semantic web after Berners-Lee's World Wide Web. 1In March, 989, Berners-Li Zhuan wrote "Suggestions on Information Management", in which ENQUIRE was mentioned and a more complicated management model was described. 1990165438+1October 12 He put forward a more formal proposal about the World Wide Web in cooperation with robert cailliau. . 1990, 165438+ 10 month, 13, he wrote the first web page on the NeXT workstation to realize the ideas in his article. During the Christmas holiday that year, Berners-Lee made all the tools needed for a network job [6]: the first World Wide Web browser (also an editor) and the first web server. On August 6th, 199 1, he published an article about the World Wide Web project on the news group alt.hypertext. This day also marks the first appearance of World Wide Web services on the Internet. Hypertext is an important concept in the World Wide Web, which originated from several projects in the 1960s. For example, Xanadu by Ted Nelson and NLS by douglas engelbart. The inspiration of these two projects comes from the memex system designed by Nivard Bush for microfilm in the paper "Think Like We Think" in 1945. Another brilliant breakthrough of Tim Berners Lee is the grafting of hypertext onto the Internet. In his book Weaving Web, he explained that he had repeatedly suggested to the users of these two technologies that it was feasible to combine them, but no one responded to his suggestion, so he finally had to solve the scheme himself. He invented the unique authentication system of global network resources: uniform resource identifier. There are many differences between the World Wide Web and other hypertext systems: * The World Wide Web requires a single connection, not a two-way connection. It allows anyone to link resources without any action by the resource owner. Compared with the early network system, this is very important to reduce the difficulty of realizing the network server and web browser, but its side effect is the stubborn disease of bad chain. * Unlike some applications such as HyperCard, the World Wide Web is not proprietary, which enables servers and clients to develop and expand independently without licensing restrictions. 1On April 30th, 993, the European Organization for Nuclear Research announced that the World Wide Web was open to anyone free of charge. Two months later, Gopher announced that it was no longer free, causing a large number of users to switch from Gopher to the World Wide Web. World Wide Web Consortium (W3C), also known as W3C Committee. 1994 10 was established in the computer science laboratory of MIT. The founder is Tim Berners Lee, the inventor of the World Wide Web. Since the 1940s, people have always dreamed of having a worldwide information base. In this database, data can not only be accessed by people all over the world, but also be easily linked to information in other places, so that users can obtain important information conveniently and quickly. It triggered the fifth information revolution. With the rapid development of science and technology, this dream has become a reality. The most popular system used at present is called WWW. Its formal definition is "WWW is a wide-area hypermedia information retrieval initiative, which provides universal access to the world's documents." In short, WWW is an Internet-based computer network, which allows users to access information from one computer to another through the Internet. Technically speaking, the World Wide Web is a collection of clients and servers that support WWW protocol and Hypertext Transfer Protocol (HTTP) on the Internet. Through it, you can access hypermedia files all over the world, including words, graphics, sounds, animations, databases and various software. Theoretically, the World Wide Web includes the whole Internet world of more than 200 million people, including all websites, gopher information stations, FTP files, Telnet public access accounts, news discussion forums and Wais databases. Therefore, the World Wide Web can be said to be the largest electronic information world in the world today, and the World Wide Web can be regarded as synonymous with the Internet. In fact, what we usually call "surfing the Internet" actually refers to connecting to the World Wide Web. WWW is the abbreviation of World Wide Web, and it can also be abbreviated as Web, and its Chinese name is World Wide Web. [Edit this paragraph] Online story late reward 1989, if Tim? 6? 1 Berners? 6? 1 Li applied for intellectual property rights for the World Wide Web he invented, so today's Internet world will be completely different. There really is a free lunch. Tim gave his invention selflessly to the whole world and took nothing. He has created a platform for countless people to get rich, but he has been suffering from no money to repair the kitchen. 1989 However, someone took the opportunity to make a fortune. Like Jeff, the founder of Amazon.com? 6? 1 Bizot, founder of Yahoo Yang Zhiyuan, founder of Netscape Mark? 6? 1 Anderson. 1989 shortly after Tim announced his invention to the public, Internet companies proliferated. Overnight, a group of rich people were born. The "father of the World Wide Web" still persists in his poor scientific research work. 1989 First Winner of the Millennium Science and Technology Award1June 989 15. At a ceremony in Espoo, Finland, the Finnish Science and Technology Award Foundation appointed 49-year-old Tim. 6? 1 Berners? 6? 1 Li is the first winner of the Millennium Science and Technology Award, the world's largest science and technology award, and awarded him a prize of 1 10,000 euros. Everyone else is worth it. It took Tim 15 years to get it. 1989 "This is really a surprise," Tim said, "but money won't drive me crazy. I have to distribute the bonus of100000 euros reasonably. My family lives in the suburbs, so it is inconvenient for children to go to school. Besides, my wife always complains that we should repair the kitchen. " From 65438 to 0989, Tim, who worked in CERN, invented the World Wide Web for the need of high-energy physics research. Four years later, Netscape launched the World Wide Web product, which immediately swept the world. The birth of the World Wide Web has brought revolutionary changes to global information exchange and dissemination, and opened the door for people to obtain information in one fell swoop. 1989 When the Finnish Science and Technology Award Foundation decided in April this year to award 1 10,000 euros of the newly established Millennium Science and Technology Award to Tim, many people felt that he was a well-deserved winner. 1989 Pekka, Chairman of the Selection Committee of the Millennium Science and Technology Award? 6? 1 Taiani called Tim's award "very popular". Eight members of the jury unanimously recommended Tim as the first winner of the Millennium Science and Technology Award among all 78 candidates. 1989 in the Internet world 1989 In the history of Internet development, there are many "grandfathers", such as Lei, the inventor of e-mail. 6? Tomlinson of 1 invented Viton? 6? CERF and Robert? 6? 1 Kahn. But only Tim invented the World Wide Web. 1989 before him, there was no browser and no "WWW", and the online world was blank. If you had applied for intellectual property rights and patents from your own WWW to the later World Wide Web for personal interests, today's Internet world would be unimaginable. Tim assumes, "In that case, there will be at least 16 different websites in the world, including CERN, Microsoft and Apple ..."1989 Many people say that Tim was stupid and gave up the opportunity to become a super rich man, but Tim doesn't think so. He believes that the patent protection of software has endangered the core spirit of promoting the development of Internet technology. "The problem is that if someone is writing a program, then a person comes from behind, takes a glance and says,' Hey, I'm sorry, I have applied for a patent for 35 to 42 sentences in your program'. This undoubtedly hurts the development of science and technology. If you think a computer can do something, you should write this idea into a computer program to realize it. This is the soul of many great technological developments ... "1989 has great commercial value in collaboration. 1989 Recall your own inventions. Tim said modestly: "Its discovery did not come from the instant inspiration of Eureka, nor did it prove the concept of gravity like an apple falling on Newton's head. On the contrary, people gradually realize that it can generate power by combining various ideas into a network (that is, a network) in a compromise way. The birth of the Internet is a response to open challenges. " 1989 "After the birth of hypertext and computers, I happened to have plenty of time and no lack of hobbies. The task that falls on my head is to combine them organically. " 1989 Tim was once asked: "Do you think it is possible to find a balance between online business activities and your initial motivation of" enjoying knowledge and coordinating with each other "?" Tim said: "There is no need to define this balance. In a balanced state, when the business volume increases, the cooperative business volume will decrease, but they are not competitive with each other. In fact, collaboration has greater commercial value. The company that learns to make better use of the network to work together may be the company that finally wins. " 1989 Perhaps, in the eyes of others, all Tim's actions are extraordinary. In Tim's eyes, life should be natural. Social Impact Because WWW provides people all over the world with the means to find and enjoy information, it can also be regarded as a collection of information that all kinds of organizations, scientific research institutions, universities and companies in the world are keen on researching and developing. It is based on Internet query. Information publishing and management system is a dynamic multimedia communication format for people to interact. Its formal expression is: "the original protocol of wide-area hypermedia information retrieval, the purpose of which is to access massive documents." What WWW has achieved is to provide a compatible means for users on the computer network to access various media in a simple way. It is the first truly global hypermedia network, which has changed the way people observe and create information. As a result, the research, development and use of WWW have quickly set off a huge upsurge all over the world. WWW was born in the Internet and later became a part of it. Today, the World Wide Web is almost synonymous with the Internet. Through it, everyone who joins it can reach every corner of the world in an instant, just plug in a telephone line (maybe your laptop or your mobile phone) on your PC, and the global information is at your fingertips! WWW doesn't actually exist anywhere in the world. In fact, users of WWW give it new meanings every day. In the Internet society, citizens (including institutions and individuals) embed all kinds of information they need to disclose into the WWW in the form of homepages, which include graphics, sounds and other media besides words. From all kinds of job advertisements to electronic bibles, it can be said that it is all-encompassing and ubiquitous. The homepage is published on the Web, mainly in the form of some HTML text (HTML is Hypertext Markup Language). With the rapid development of mobile Internet access, some experts recently called it WAP and WWW. WAP has become a global de facto standard for accessing wireless information services through mobile phones or other wireless terminals. Its development and application are infinite. [Edit this paragraph] The composition of WWW] The client is a program that needs something, while the server is a program that provides something. A client can request from many different servers. Servers can also provide services to many different clients. Usually, the client starts a conversation with the server. Servers are usually automated programs that wait for requests from clients. The client usually runs as a request from the user or from every program similar to the user. A protocol is a definition of various methods for a client to request a server and how the server responds to the request. WWW client can also be called browser. The usual clients on the World Wide Web mainly include IE, Firefox, safia, opera and so on. In the Web, the client's task is: 1. Help you make a request (usually launched when you click the link point). 2. Send your request to the server. 3. Report the requested results to you by correctly decoding the direct image, submitting the HTML document and transferring various files to the corresponding "viewer". Viewer is a program that can be called by WWW clients to present specific types of files. When a sound file is viewed and downloaded by your WWW client, it can only be "observed" by some programs (such as "media player" under Windows). Generally speaking, WWW clients can make requests not only to Web servers, but also to other servers (such as Gopher, FTP, news and mail). Server 1. Accept the request. Check the legality of the request, including security screening. 3. Obtain and make data according to the request, including Java scripts and programs, CGI scripts and programs, set appropriate MIME types for files, and pre-process and post-process the data. 4. Send the information to the requesting client. [Edit this paragraph] WWW adopts the client/server working mode, as follows: (1) Users use browsers or other programs to establish a connection between the client and the server and send browsing requests. (2) After receiving the request, the 2)Web server returns information to the client. (3) When the communication is completed, close the connection. [Edit this paragraph] The English name of the World Wide Web is the English phrase "surfing the Internet", that is, browsing the Internet. First of all, a writer named Jean Armored Polly made this concept accepted by the public through his work "Online". This book was officially published by Wilson Publishing House on June 1992. She may have put forward this concept independently, but it has been used in news groups from 199 1 to 1992. Some people remember that a hacker used this word two years ago. Pauli is sometimes called "net mom" in the field of Internet. [1] Although English words are usually written as one word all over the world (without spaces or hyphens), the full name World Wide Web and its abbreviation World Wide Web are now widely used in some formal English. The earliest literature talked about the WorldWideWeb (this is an excellent example of a programmer's preference for conjunctions, that is, connecting several words together to form a new word) or the World Wide Web (connected by hyphens, so that this version of the name is closest to formal English usage). Interestingly, "World Wide Web" has become one of the few abbreviations in English with syllables longer than its original name. In English, the World Wide Web has three syllables, while the single letter W has three syllables. WWW = world weather watch World Meteorological Monitoring Network is a global meteorological operational system planned and established by the World Meteorological Organization. English abbreviation WWW. Through cooperation among its members, world weather watch comprehensively organizes, plans and coordinates the layout of the global meteorological station network, meteorological observation, meteorological communication, analysis and forecast and meteorological data processing, so that all members of the World Meteorological Organization can obtain meteorological information needed for meteorological operations, services and research. The difference between the World Wide Web, the Internet and the Internet To be precise, there are differences between the World Wide Web, the Internet and the Internet. On the difference between "Internet" and "Internet" In the article "On the phenomenon of one thing with many names in computer and network terms", I mentioned the naming problem of "Internet". But in fact, the word "Internet" is still in use. Are these two names completely different when used, or do they refer to two different concepts? The answer is definitely the latter. To answer this question, we must first review the history of the Internet. Internet was born in America 1969. Originally called "ARPANET", it was a military research system, and later became an academic system connecting computers of universities and institutions of higher learning. Now it has developed into an open global computer network system covering five continents 150 countries, with many service providers. Ordinary computer users only need a personal computer to connect with an Internet service provider through a telephone line to access the Internet. But the Internet is not the only one in the world. For example, in Europe, transnational Internet networks include Euronet, EARN, EIN, BITNET in the United States, and FedEx networks (global BBS system) all over the world. Knowing the above situation, we can know that capitalized "internet" ("interreto" in Esperanto) and lowercase "Internet" ("Interreto" in Esperanto) refer to different objects. When we talk about the world's largest Internet mentioned above, that is, the Internet we usually use, we call it "Internet" or "Internet", although the name of the latter is not standardized. Here, "Internet" appears as a proper noun, so the first letter must be capitalized. However, as a common noun, that is, "Internet" starting with lowercase letters generally refers to a large network formed by the interconnection of multiple computer networks. According to the approval of the National Science and Technology Examination and Approval Committee, such a network system can be called "Internet". That is to say, the Internet and other similar large-scale network systems connected by computers can all be regarded as the "Internet", and the Internet is only the largest one in the Internet. In the 2002 supplement of Modern Chinese Dictionary, the definitions of Internet and Internet are "a network formed by the interconnection of several computer networks" and "the largest computer Internet in the world at present, which evolved from ARPA network in the United States". For reference. Finally, as a proper noun, besides the first letter, the Internet usually adds the article la Interreto, which can also be abbreviated as "la Reto". WWW, World Wide Web, TTT-Almost Perfect Translation Anyone who accesses the Internet does not know the important role of WWW? To enter the web address, you must type these three letters first. These three letters are abbreviations of the English initials "World Wide Web". WWW has been translated into World Wide Web, World Wide Web, Hypermedia World Wide Web and so on. In China, it was finally translated into the World Wide Web by the National Science and Technology Terminology Examination Committee. In the article GZ18 "Wonderful Translation of WWW", Mr. Zhu Guo praised his Chinese translation of the word "Wang Wanwei", which was not excessive. The nearly perfect translation beauty of the word "World Wide Web" lies in its meaning, form and vividness. What a miraculous translation! Coincidentally, the translated word "TTT" of "WWW" is also composed of three identical letters, and the translation is also amazing. "TTT" is "Tut-Tera Teksa" in esperanto? O "abbreviation. According to the information in Komputada leksikono (a computer professional vocabulary) written by Russian Esperanto Sergio Pokrovskij, the original translation form of "WWW" was "Tutmonda Tekso". On the day when this translation name appeared, that is,1August 5, 994, someone immediately suggested changing it to "Tut-Tera Tekso" on the Internet. Eight days later, August 13 was translated into "Tut-Tera Teksa" by another person at the suggestion of an anonymous person. O "(literally" World Wide Web "). The abbreviation TTT of this translated name is neat in form and completely consistent in semantics, which is easy to read, remember and write. This is the creation of collective wisdom. It also eloquently proves that Esperanto is powerful, flexible and adaptable, which is not inferior to Chinese and English at all (please compare the French translation word "Forum elektronique mondial" and the Spanish translation word "Telarana Mundial" in WWW, whose abbreviations are "FEM" and "TM" respectively). Writing here, I can't help but think of a famous saying by Mr. Yan Fu, a modern translation master in China: "A famous person stands, and the moon is long." A good translation can only be produced after a long period of searching and thinking by translators and sometimes even several translators. The World Wide Web is a collection of countless websites and web pages, which together constitute the most important part of the Internet (the Internet also includes e-mail, newsgroups and newsgroups). It is actually a collection of multimedia, connected by hyperlinks. What we usually watch online through a web browser is the content of the World Wide Web. I will introduce some Esperanto terms about the World Wide Web and browsing the World Wide Web in future posts. Internet is a network that connects computer networks with different structures distributed all over the world with various transmission media. So some people call it the network of the network, and Chinese translation is Internet, Internet, Internet and so on. The main services provided by the Internet are World Wide Web (WWW), file transfer (FTP), e-mail, remote login, etc. WWW (World Wide Web) is abbreviated as W3, sometimes called Web, and translated into Chinese as World Wide Web, World Wide Web and so on. The World Wide Web was developed by the European Centre for Nuclear Physics (ERN). Its purpose is to provide communication, information exchange and information inquiry facilities for scientists all over the world by using the Internet. The World Wide Web is based on the client/server model. WWW is based on Hypertext Markup Language (html) and Hypertext Transfer Protocol (http). An information browsing system that can provide a consistent user interface for Internet services. Among them, the WWW server uses hypertext links to link information pages, which can be placed on the same host or in different geographical locations. This link is maintained by Uniform Resource Locator (URL), and the WWW client software (namely WWW browser) is responsible for displaying information and sending requests to the server. Internet uses hypertext and hypermedia to organize information and extend information links to the whole Internet. At present, users can not only access the information of the Web server, but also access the network services such as FTP and Telnet by using WWW. Therefore, it has become the most widely used and promising access tool on the Internet, and is playing an increasingly important role in business. The WWW client program is called WWW browser on the Internet, which is the software used to browse the WWW homepage on the Internet. At present, the most popular browser software mainly includes Netscape communicator and Microsoft ie browser. WWW browsing provides a user-friendly information query interface, and users only need to make a query request. As for where to query, how to query is done automatically by WWW. Therefore, WWW has brought users worldwide hypertext services. Users can transmit the required text, images, sounds and other information from anywhere in the world through the Internet by manipulating the mouse. WWW makes the very complex Internet very simple and easy to use. WWW browser not only opens up a convenient way for users to find rich and diverse homepage information resources on the Internet, but also provides powerful communication means such as Usenet newsgroup, email and FTP protocol.
