What is the communication protocol of the internet?

The main communication protocol used by the Internet is "TCP/IP protocol". TCP/IP transmission protocol, which is the transmission control/network protocol, is also called the network communication protocol; it is the most basic in the use of the network. The TCP/IP transmission protocol stipulates the standards and methods for communication between various parts of the Internet.

The main communication protocol used by the Internet is the "TCP/IP protocol".

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) refers to a protocol suite that can realize information transmission between multiple different networks.

TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol Among them, TCP protocol and IP protocol are the most representative, so they are called TCP/IP protocol.

TCP/IP transmission protocol, namely transmission control/network protocol, is also called network communication protocol. It is the most basic communication protocol used in networks. The TCP/IP transport protocol stipulates the standards and methods for communication between various parts of the Internet.

Moreover, TCP/IP transmission protocols are two important protocols that ensure timely and complete transmission of network data information. The TCP/IP transmission protocol is strictly 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 the Internet. The main protocols of the application layer include Telnet, FTP, SMTP, etc., which are used to receive data from the transport layer or transmit data according to different application requirements and methods. To the transport layer;

The main protocols of the transport layer are UDP and TCP, which are channels for users to use the platform and the internal data of the computer information network to achieve data transmission and data sharing;

Network The main protocols of the layer are ICMP, IP, and IGMP, which are mainly responsible for the transmission of data packets in the network;

The network access layer, also called the network interface layer or data link layer, the main protocols are ARP and RARP , the main function is to provide link management error detection, effective processing of information details related to different communication media, etc.
