The basic structure and technology of the internet originated from ARPANET. ARPANET is a milestone in the development of computer network technology. Its research results have played an important role in promoting the development of network technology and laid the foundation for the formation of the Internet. Arpanet (Arpanet) was the world's first operational packet switching network developed by the U.S. Defense Advanced Research Projects Agency. It is the ancestor of the global Internet.

The basic structure and technology of the internet originated from ARPANET.

The Internet began in 1969 with the Arpanet in the United States. Usually internet refers to the Internet in general, while Internet refers to the Internet specifically. This method of connecting computer networks to each other can be called "network interconnection". On this basis, a global Internet network covering the world called the Internet was developed, which is a network structure that is interconnected. The Internet is not the same as the World Wide Web. The World Wide Web is just a global system based on hypertext links and is one of the services that the Internet can provide.

ARPANET introduction

arpanet (Arpanet) was the world's first operational packet developed by the U.S. Department of Defense Advanced Research Projects Agency Switching network is the ancestor of the global Internet.

ARPANET is a milestone in the development of computer network technology. Its research results have played an important role in promoting the development of network technology and laid the foundation for the formation of the Internet. NOVELL is a company that launches the NetWare network operating system, and ALOHA is a protocol for dynamic allocation of media.

What is the origin of the basic structure and technology of the internet?

internet introduction

internet means the Internet, also known as the Internet, according to the transliteration It is called the Internet and the Internet is a huge network connected between networks. These networks are connected by a common set of protocols to form a logically single and huge global network. In this network, there are network devices such as switches and routers, various connection links, a wide variety of servers and countless computers and terminals. Using the Internet, information can be sent to people thousands of miles away instantly. It is the foundation of the information society.

The Internet began in the United States in 1969. It was first used for military connections by the US military under the agreement established by ARPA (Arpanet, US Defense Research Project Agency), and later used by the University of California, Los Angeles, Stanford University Graduate School, UCSB (University of California) and Utah in the southwestern United States. State University's four main computers are connected. The agreement was executed by BBN Technologies of Cambridge, Massachusetts, which built the IMP (Interface Information Processor), a custom Honeywell DDP-516 Minicomputer. After BBN's design and construction of software design, routing, traffic control and network control, they are assigned to various sites to serve as gateways to ARPANET. BBN successively manufactured 4 IMPs between August 30, 1969 and the end of the year, and began to go online.

Another wide area network that promotes the development of the Internet is the NSF network. It was originally funded by the National Science Foundation to connect five supercomputer centers in the United States for more than 100 American universities to share their data. resource. The NSF network also uses TCP/IP protocol and is connected to the Internet.

Both the ARPA network and the NSF network originally served scientific research, and their main purpose is to provide users with valuable resources to share large mainframes. As the number of connected hosts increases, more and more people use the Internet as a tool for communication and exchange. Some companies have also launched commercial activities on the Internet. With the commercialization of the Internet, its huge potential in communications, information retrieval, customer service, etc. has been tapped, making the Internet a qualitative leap and eventually going global.
