The origin of the internet

Internet is an international network system in which computers are interconnected. Its prototype is ARPA net. 1969 The Advanced Research Projects Agency under the US Department of Defense signed a contract with Bolt, Beraneck and Newman to develop and build ARPA networks. The way to build this network is to connect multiple personal computers with multiple channels. In this way, even if it is hit by war, the computer can still carry out military research, military defense exchange and command without being affected. American universities joined the ARPA network project in the 1970s, and some European universities established connections with the APPA network in the late 1970s. In the 1990s, although ARPA originally used for military purposes withdrew from the diachronic stage with the end of the Cold War, its method provided a successful example for the networking of thousands of civil computers. Today, countless computers can be connected very conveniently, and thousands of people living around the world can communicate, contact and express their opinions through networked computers.

In the past few decades, the Internet has developed rapidly. Everyone who uses the Internet can access the infinite cyberspace in various ways and enjoy the colorful network resources updated at any time. Most universities, colleges, scientific research institutions and companies provide network services for their students, teachers and employees. Many organizations and libraries have free computer networks, and there are all kinds of low-cost internet cafes on the street. Some large Internet service providers (ISPs), such as AOL, CompuServe, Microsoft Network and Prodigy, not only provide users with their own huge private network information database, but also provide Internet users with paths to other Internet service providers through hyperlinks.

Anyone who uses the Internet can conveniently use the information exchange, information retrieval, download and storage services provided by the network. Although these methods are difficult to classify accurately, they can be reused without restriction. So far, these projects include e-mail, electronic detonators or mail bombers or mailing list servers, newsgroups, chat rooms, the World Wide Web and bulletin boards. These services can be used for the transmission of various texts between networks; Some can also transmit sound, images and video programs between networks. All these available online services combine to make the Internet a very unique cyberspace or mass media. Although this electronic space has no specific geographical location, compared with traditional media, the information exchange and information services it provides can be enjoyed by any online user in the world in a very cheap and convenient way.

Using e-mail, one person can send letters and other text messages to another person or people. These letters and information sent back and forth are stored in personal mailboxes on the Internet. People who receive letters and messages can view and read their emails immediately, or view and read them later and reply. Compared with sending letters through postal agencies, this method is fast, safe, confidential, convenient and cheap. Electronic detonator is a set of e-mails, which can be used by computer users to send an e-mail to the website first, and then the e-mail will be sent to many subscribers immediately. Newsgroups serve any unspecified readers, providing them with past, present and ongoing news and news topic search. There are thousands of newsgroups on the Internet, whose main function is to exchange all kinds of information on a global scale. While exchanging updated information at any time, these newsgroups also provide each reader with an electronic tablet computer, through which each reader can express his views, opinions and opinions on the Internet in an open or anonymous way, and readers can also enter the chat room to communicate with readers anywhere in the world. In this way, every reader can become a center and let his voice be heard all over the world. Imagine the scene of countless people communicating on the Internet. It is no exaggeration to say that the content on the Internet is as colorful and different as every idea.

The most commendable thing about the Internet is its global network system (W.W.W). It allows users to search and store information on the computer no matter how far away. In some cases, users can also return to communicate with any designated website. It can be said that the network is a huge treasure house of resources stored on computers all over the world. There are not only text files, but also countless beautiful web pages on the Internet. Every webpage has its own website-each website takes you into different electronic spaces like a phone number. Many websites also have e-mail addresses of editors and authors for users to communicate with. Usually, these websites also provide users with other related content and hyperlinks to related websites, through which users can freely swim in the infinite electronic space.

From the perspective of publishing industry, the Internet is a huge information trading platform. On this platform, you can hear voices from all over the world, including readers, commentators and researchers. Any government, non-governmental organizations, companies, academic institutions and individuals can publish information through networked computers. The information published by publishers can be published to specific objects or to all Internet users. So far, no international organization, government or enterprise group can control and manipulate the Internet as effectively as traditional media. Therefore, the Internet will become a powerful weapon to challenge authoritarian governments and promote democracy, especially freedom of speech.
