The English name of Internet is Internet, and the Chinese translation is Internet. Some people call it the Internet or the World Wide Web.
The Internet began to develop in the late 1960s. Initially, it was a special computer network dedicated to military research in the United States, and later MIL-net and European military networks were established. With the rapid development of special computer network technology in the mid-1990s, it has become a global information network.
It is a concrete network entity with no specific network boundary, and generally refers to a network connected by a gateway, that is, a global computer network composed of various types and scales of independently operated and managed computer networks. The computer networks that make up the Internet include local area network (LAN), metropolitan area network (MAN) and large-scale wide area network (WAN). These networks connect the network resources of universities, companies, scientific research institutions and organizations in different countries through ordinary telephone lines, high-speed dedicated lines, satellites, microwaves, optical cables, etc., to communicate and exchange information and realize the sharing of resources. The basic protocol of Internet interconnection is TCP/IP. Internet has many powerful functions, including email, Telnet, interactive information query (WWW, Gopher), file transfer (FTP), electronic forum (BBS) and interactive multi-user service (Talk, Chat). After 1992, with the commercial network entering the Internet, the Internet has now become the largest commercial computer network in the world. China has officially joined the Internet since April 1994. At present, there are 10 Internet organizations approved to be established in China, namely: China Telecom Public Internet (CHINANET), China Unicom Network (UNINET), China Netcom Network (CNCNCNET), Jitong Network (GBNET), cmnet Network (CM-NET) and China Satellite Internet (CSNET). These six commercial networks can provide public services to the society. In addition, there are four private Internet: CSTNET (Science and Technology Network), China Education Network (CERNET), CIETNET and Great Wall Network. The future Internet will develop in three directions: commercialization, security and broadband transmission. With the entry of commercial networks and a large number of commercial companies, the Internet can provide services for more users in a wider range and promote the development of the Internet at an unprecedented speed and scale. Driven by commercial organizations, the Internet will soon be as popular as telephone and television. Openness is a major feature of the Internet, but it also brings a problem that hinders its practical use: poor confidentiality. Therefore, strengthening the research on Internet security technology and security has attracted the attention of all countries. In the future, the Internet will continue to retain its open features, and at the same time, it will have a highly confidential service field. At present, the information transmission rate of the Internet backbone network has exceeded 2.5Gbps. Due to the rapid growth of Internet users in recent years, especially the application of multimedia, the information traffic on the network has increased by more than 10 times, which makes the NSF-net, which is not too slow, overwhelmed. Increasing Internet bandwidth and increasing information transmission rate are becoming the key to the sustainable development of the Internet. The appearance of the Internet has changed the way people use computers. The appearance of the Internet has changed the way people use it. Anyone who has access to the Internet can freely exchange information with people all over the world by using countless resources on various networks and computers, and complete complicated tasks that were unimaginable before.
Question 2: What's the difference between Internet and Internet? Generally speaking, the huge network connected in series can be translated as "Internet" network, and also transliterated as Internet or Internet. At the beginning of the development of1990s, some people in Taiwan Province province also called it the international network or the international computer network because of its cross-international connection. It refers to the world's largest global internet developed on the basis of ARPA network. Internet (English: international network or Internet), translated as Internet in Taiwan Province Province, is a "network-connected network", which can be any single physical network. These networks are connected through a set of common protocols to form a logically single network. This method of connecting computer networks together is called "network interconnection". 1995101On October 24th, FNC (Federal Network Council) passed a resolution on the definition of Internet: "FNC believes that the following languages reflect the definition of the word' Internet'. Therefore, the Internet and the Internet are the same thing.
Question 3: What's the difference between Internet and Internet? Network consists of nodes and lines, representing many objects and their relationships. Mathematically, the network is a graph, which is generally considered as a weighted graph. In addition to the mathematical definition, the network also has a specific physical meaning, that is, the network is an abstract model from a certain kind of practical problems. In the computer field, the network is a virtual platform for information transmission, reception and sharing. Through it, the information of various points, surfaces and bodies is linked together, so as to realize the sharing of these resources. Network is the most important invention in the history of human development, which has promoted the development of science and technology and human society.
Internet (English: Internetwork), also known as the Internet, or the transliteration of Internet and Internet, is a huge network connected by a set of general protocols, forming a logically single huge international network. This method of connecting computer networks together can be called "network interconnection", and on this basis, the global internet covering the whole world is developed, which is called Internet, that is, the interconnected network structure. The Internet is different from the World Wide Web, which is just a global system based on hypertext links and one of the services that the Internet can provide.
Question 4: What is the difference between the Internet and the World Wide Web?
World Wide Web: Also known as World Wide Web. The history of the World Wide Web is very short. 1989, researchers of CERN (European Particle Physics Laboratory) hope to develop a remote access system with resources, which can provide a unified interface to access various types of information, including text, images, audio and video information. 1990, all kinds of people completed the earliest browser products, 199 1 year, and published WWW internally, which was the beginning of the World Wide Web. At present, most well-known companies have established their own World Wide Web sites on the Internet.
What is the Internet?
The Internet, also known as the Internet, has a history of more than 20 years. Its predecessor is the American Defense Computer Internet (ARPA), and now it has developed into a global computer internet. This network is the computer network with the richest information resources in the world, and is recognized as the embryonic form of the future international information superhighway.
There are tens of thousands of technical data databases on the Internet, and their information media include data, images, words, sounds and other forms. Information attributes include data, exchange software, books, files and other categories; Information content involves communication, computer, agriculture, biology, astronomy, medicine, politics, law, military affairs, music and other aspects.
At present, there are four Internet companies operating in China, namely: China Net operated by China Telecom; China Jinqiao Information Network (GB-net, operated by Jitong Company); China Unicom Computer Internet (UNI-net, operated by Unicom); And China Netcom Computer Internet (CNC-net, operated by China Network Communication Co., Ltd.). In addition, there are China education and scientific research computer Internet (CER network, managed by the Ministry of Education), cstnet (CST-net, managed by China Academy of Sciences) and other private Internet. All the above backbone networks can access the Internet through the national gateway.
It can be seen that the World Wide Web is a part of the Internet.
In fact, WWW( World Wide Web global, interactive, dynamic, multi-platform, distributed and graphical information system based on the Internet. It is just a network service built on the Internet. It was originally developed to share research results among scientists, who can share research results online in the form of pictures and texts. Its basic concept is hypertext. If you have used any online help system on indows, you will have a better understanding of its structure. Now, the application of WWW has gone far beyond the original idea and become one of the most popular applications on the Internet. Its appearance has greatly promoted the popularity of the Internet.
Question 5: What is the difference between the Internet and the Internet? What is the scope of the Internet? The network includes the Internet, which has too much work. Let me give you an example. For example, if you do online sales customer service, online consultation, open a Taobao shop, and do online customer service, as long as you work through the Internet, it is the scope of work of the Internet.
Question 6: What's the difference between Internet and broadband? They are not the same concept. Internet is a platform for people to interact online, but broadband is a transmission tool provided by operators. Broadband, also called bandwidth, is the speed provided by operators. Family types are: 1MB, 2MB, 3MB, etc. Company use 10MB, 50MB, etc.
Question 7: What's the difference between Ethernet and Internet? Let me tell you a simple one.
Ethernet is Ethernet.
The running speed is 10 Mbps, 100 Mbps, 1 Gbps, 10 Gbps.
Transmission media are twisted pair and optical fiber.
Ethernet uses CSMA/CD (Carrier Sense Multiple Access and Collision Detection) technology.
Internet The Internet originated from ARPANET.
This is not the same concept as Gong Yi. It does not use any specific transmission medium, it contains all the media and technologies.
It is a large network that connects all kinds of networks and consists of many small networks.
Question 8: The Internet and Our Life The world economist said, "No matter what you are doing, no matter what ideas you have, you must meet the Internet and get used to it. There is no other choice. "
Ten years ago, when people were still very unfamiliar with the Internet, the Internet came into our lives with the hope of 2 1 century modern civilization. In recent years, with the development of computer industry, the development speed of Internet is unimaginable in any other industry, just like a wild horse running on the endless grassland. I believe that most people didn't realize how the Internet would affect our real life at that time. After several years of rapid development, people gradually realize that the Internet has gradually become an inseparable part of our lives. Our present life needs the Internet, and our future life will also depend on it. This is not an alarmist. It has become an indisputable fact that the Internet is changing our lives.
From the initial dial-up Internet access to ISDN, from ADSL to optical fiber access, network technology is changing with each passing day. The Internet has brought more and more changes to our lives. The network not only brings great convenience to your work, but also brings great convenience to your life. In the past, you needed to look up information in many books. Now, as long as you type a few words in the search engine, you can find the information you need in a few seconds. In the past, you had to learn about some national events and news trends from TV, newspapers and radio. Now, you can know the latest and fastest news through online search. In the past, separated friends had to keep in touch by writing letters. Now, friends keep in touch through e-mail, and they can also chat in time through QQ, MSN, etc. I used to want to know what the latest new clothes were, and I had to sacrifice a day to go shopping. It's tiring, and it's not necessarily rewarding. Now I want to see what is a fashionable new brand of clothes. Just click on "brand house chinapp" and I will have the answer I want to know. In the past, you had to go to the cinema to see movies. Now, you can see the movie you want by searching online. In the past, if you liked things from other places, you had to ask your friends there to buy them for you. Now, you can shop online and pay directly online, and you can buy what you like immediately.
The wide application of the network has also brought more benefits to enterprises, saving a lot of unnecessary personnel expenses, unnecessary intermediate processes and many possible mistakes. Now, many enterprises use the network platform to complete transactions. Many large and small enterprises also show themselves on the Internet in the form of corporate websites to let people know about them.
The Internet has changed life. I think all friends who surf the internet must have a deep understanding. All netizens should have changed their lives and work. From looking for information, watching news, sending emails, looking for brands to online shopping, everyone can see it and every netizen can understand it. The Internet has also changed many people's lifestyles. While bringing convenience to people, it also brings disadvantages. With the internet, many people are lazy. Many people would rather stay in front of the computer to kill time than stay with relatives and friends, which leads to the alienation of family and friendship. Cold e-mails have replaced those letters with familiar handwriting. Letters can be kept forever, but emails can be deleted at any time. Many people are addicted to illusory online chat and online games, which are hard to extricate themselves and are getting farther and farther away from real life. The internet has also been used by some malicious people, resulting in many online scams, viruses and bad information harmful to society. Only by taking its essence and discarding its dross can the Internet better serve our lives, change our lives and make our economic construction further.
Recently, a famous quality education expert criticized the Internet, accusing the Internet giants of making money, accusing online games of making many children addicted to the Internet and neglecting their studies, and online pornography made some young people think crazily and lose their morality. This view has won the approval of many parents. Most parents think that the internet is not a good thing, and it is full of temptations for children. It seems that the world is getting worse, morality is declining, good people are learning bad, and everything is the fault of the internet.
To be fair, is this really the case? Don't! The network is just a tool in our hands, just like a knife, which can be used by us. If we succeed ... >>
Question 9: The relationship between computers and the Internet. The communication of computer network needs protocols to control information transmission and other corresponding network software. This is because only using hardware to communicate is as difficult as using binary programming. In order to facilitate network programming, computers usually use complex software to connect to the network. These softwares provide convenient high-level interfaces for applications, and automatically handle most low-level communication details and problems. Therefore, most applications rely on network software for communication and do not directly deal with network hardware.
Communication in the network refers to the communication between entities in different systems. Entities refer to terminals, application software and communication processes that can send and receive information.
Only on the basis of communication can two entities in different systems in a computer network exchange information and share network resources.
Question 10: What's the difference between Internet, Ethernet and Internet? Internet is a free translation of Internet, and Internet is a transliteration of Internet. The two are equivalent and it is a global wide area network.
Ethernet is a local area network technology, which can be regarded as the underlying protocol of the network.
