The core technology used by the Internet is the 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 the channels through which users use the platform and the internal data of the computer information network to realize data transmission and data sharing; the main protocols of the network layer are ICMP, IP, and IGMP. Responsible for the transmission of data packets in the network; and the network access layer, also called the network interface layer or data link layer, the main protocols are ARP, RARP, the main function is to provide link management error detection, information details about different communication media Problems are dealt with effectively, etc.
