It is a huge network connected in series between networks, which are connected by a common protocol to logically form a single huge international network. The general Internet refers to the general Internet, and the Internet refers to the special Internet.
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. The World Wide Web is just a global system based on hypertext links, and it is one of the services that the Internet can provide.

Internet development
In the 1950 s, communication researchers realized the need to allow regular communication between different computer users and communication networks. This promotes the research on decentralized networks, queuing theory and packet switching. From 65438 to 0960, the ARPA network created by the Advanced Research Projects Agency (ARPA) of the US Department of Defense for the consideration of the Cold War triggered technological progress and made it the center of Internet development.
1973, ARPA network was expanded to Internet, and the first computers were connected to Britain and Norway. 1974, robert kahn of ARPA and Vinton Cerf of Stanford proposed the TCP/IP protocol, which defined the method of transmitting messages between computer networks (they also won the Turing Prize in 2004).
1 98365438+1October1,ARPA network changed the network core protocol from NCP to TCP/IP protocol. From 65438 to 0986, the National Science Foundation established the backbone network NSFNET, which was an important step in the history of the Internet. 1994, NSFNET was put into commercial operation.
1995 with the opening of the internet to business, other important networks successfully accessed in the internet include newsgroups, Bitnet and various commercial X.25 networks. From 65438 to 0990, the whole network is open to the public. In August, Tim Berners Lee began to promote his World Wide Web project. Two years ago, CERN invented HTML, HTTP and the first few web pages.
In the late period of 1994, public interest increased steadily in pre-academic and technical internet. 1996 the word "internet" is widely circulated, but it refers to almost the whole world wide web. During this period, ten years later, the Internet successfully accommodated most of the original computer networks (although some networks such as FidoNet remained independent).
This rapid development is attributed to the lack of central control over the Internet and the non-private nature of Internet protocols. The former leads to the organic growth of the Internet, while the latter encourages compatibility among manufacturers and prevents a company from monopolizing the Internet. The success of the Internet can be seen from the case differentiation of the word "Internet".
At first, the word Internet represented those networks built with IP protocol, but today, it has been extended to refer to various types of networks, and is no longer limited to IP networks. So the lowercase Internet (the initial "I" is lowercase) is a collection of any separated physical networks, which are connected by a set of common protocols to form a logically single network.
Capitalized Internet (the initial letter "I" is a capital letter) refers to ARPA network, and then uses IP protocol to link various physical networks into this single logical network. Capitalized Internet is a form of lowercase Internet, but the reverse is not the case.
Since 2002, some scholars began to suggest that the word "Internet" is expressed in lowercase, on the grounds that the Internet has become a part of human life and lost its proprietary meaning.
In 20 16, the Associated Press thought that "Internet" had become an ordinary thing like "telephone" and did not have the meaning of exclusive trademark, so it began to stipulate that "Internet" and "web" were lowercase in its format manual, and the new york Times followed suit, but at the same time, some media put forward different opinions.
