Editor to share with you what internet is called in China on the Internet, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Internet is called Internet or Internet in China. Internet is a collection of global information resources, a global network connected by computers that use a common language to communicate with each other. Once you connect to any of its nodes, it means that your computer has been connected to the Internet network.

The Internet, namely the Internet (Internet), is currently the largest computer network in the world. It is a global network connected by computers that use a common language to communicate with each other. Once you connect to any of its nodes, it means that your computer has been connected to the Internet network.

The Internet began in the United States in 1969. Under the agreement made by ARPA, the US military first used military connections, and then connected four major computers at the University of California, Los Angeles, Stanford University Research School, UCSB and the University of Utah in the southwestern United States. The agreement, implemented by BBN and MA of Cambridge University, came online in December 1969.

Another wide area network that promotes the development of internet is NSF, which was originally funded by the National Science Foundation to connect five supercomputer centers across the United States so that more than 100 American universities can share their resources. NSF network also adopts TCP/IP protocol and is connected with internet.

At first, both ARPA and NSF networks serve for scientific research, and their main purpose is to provide users with valuable resources for sharing mainframes. With the increase of the number of access hosts, more and more people use internet as a tool for communication and communication. Some companies have also launched business activities on internet one after another. With the commercialization of internet, its great potential in communication, information retrieval and customer service has been excavated, which makes internet have a qualitative leap, and finally go global.

Network core protocol

The computer network is made up of many computers. In order to transfer data between the computers in the network, two things must be done: the destination address of the data transmission and the measures to ensure the rapid and reliable transmission of the data. This is because the data is easily lost or mistransmitted in the process of transmission. Internet uses a special computer language (protocol) to ensure that the data can reach the designated destination safely and reliably. This language is divided into two parts: TCP (Transmission Control Protocol Transmission Control Protocol) and IP (Internet Protocol Internetwork Protocol) sure network marketing theory.

The data transmission process of TCP/IP protocol: the communication mode adopted by TCP/IP protocol is packet switching. The so-called packet switching means that the data is divided into several segments during transmission, and each data segment is called a data packet. The basic transmission unit of TCP/IP protocol is data packet. TCP/IP protocol mainly includes two main protocols, namely TCP protocol and IP protocol. These two protocols can be used jointly or with other protocols. They mainly perform the following functions in the process of data transmission:

The main contents are as follows: (1) first, the data is divided into several data packets by the TCP protocol, and each packet is written with a sequence number, so that the receiver can restore the data to the original format.

(2) the IP protocol writes the address of the sending host and the receiving host to each packet. Once the source address and destination address are written, the packet can transmit data over the physical network. IP protocol also has the function of using routing algorithms for routing.

(3) these packets can be transmitted through different transmission paths (routes). Due to different paths and other reasons, the order may be reversed, data loss, data distortion or even repetition may occur. These problems are handled by the TCP protocol, which has the function of checking and handling errors, and can request the sender to resend if necessary. In short, IP protocol is responsible for data transmission, while TCP protocol is responsible for reliable data transmission.
