What is the most basic communication protocol of the Internet?
The most basic communication protocol of the Internet is TCP/IP, and the TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol consisting of FTP, SMTP, TCP, UDP, IP, etc. composed of protocol suites.
#The most basic communication protocol of the Internet is TCP/IP.
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 refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol, the TCP protocol and IP protocol The most representative, so it is 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 to the transport layer according to different application requirements and methods; the transport layer The main protocols of the network layer are UDP and TCP, which are the channels through which the user uses 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, which are mainly responsible for the processing of data packets in the network. transmission, etc.; and the network access layer, also called the network interface layer or data link layer, the main protocols are ARP and RARP. Its main functions are to provide link management error detection and effectively handle information details related to different communication media.

Every host connected to the Internet has a uniquely identifiable address called an IP address. The IP address is a unified address format provided by the IP protocol. It assigns a logical address to each network and each host on the Internet to shield the differences in physical addresses. Because of the unique address such as IP address, it is ensured that users can efficiently and conveniently select the objects they need from thousands of computers when operating on connected computers.
