This article mainly introduces what is the most basic communication protocol of the Internet in the computer network, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The most basic communication protocol of the Internet is TCP/IP, and TCP/IP protocol not only refers to TCP and IP protocols, but also refers to a protocol suite composed of FTP, SMTP, TCP, UDP, IP and other protocols.

The most basic communication protocol of the Internet is TCP/IP.

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol / Internet Protocol) is a suite of protocols that can transfer information between different networks. TCP/IP protocol not only refers to TCP and IP protocols, but also refers to a protocol suite composed of FTP, SMTP, TCP, UDP, IP and other protocols. Only because TCP and IP protocols are the most representative of TCP/IP protocols, they are called TCP/IP protocols.

TCP/IP transport protocol, that is, transmission control / network protocol, is also called network communication protocol. It is the most basic communication protocol in the use of network. The TCP/IP transport protocol defines the standards and methods for communication among various parts of the Internet. Moreover, TCP/IP transmission protocol is two important protocols to ensure the timely and complete transmission of network data information. Strictly speaking, TCP/IP transport protocol is a four-layer architecture, including the application layer, transport layer, network layer and data link layer. TCP/IP protocol is the most basic protocol of Internet, in which the main protocols of the application layer are Telnet, FTP, SMTP, etc., which are used to receive data from the transport layer or transmit the data to the transport layer according to different application requirements and methods; the main protocols of the transport layer are UDP and TCP, which are the channels for users to use the platform and the internal data of the computer information network, which can realize data transmission and data sharing. The main protocols of the network layer are ICMP, IP, IGMP, which are mainly responsible for the transmission of data packets in the network, while the network access layer, also known as the network interface layer or data link layer, the main protocols are ARP, RARP, the main functions are to provide link management error detection, to effectively deal with the details of different communication media and so on.

Thank you for reading this article carefully. I hope the article "what is the most basic communication protocol of the Internet in the computer network" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
