The most basic communication protocol on the Internet is the TCP/IP protocol. TCP/IP refers to a protocol suite that can realize information transmission between multiple different networks. It is the most basic communication protocol in the use of networks. It stipulates the standards and methods for communication in various parts of the Internet.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

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

TCP/IP protocol introduction

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) refers to the ability to A protocol suite for information transmission between 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, 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.

What is the most basic communication protocol of the Internet?

TCP/IP protocol is the most basic protocol of the Internet:

  • The main protocols of the application layer include Telnet, FTP, SMTP, etc. , is used to receive data from the transport layer or transmit 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 used by users The channel that combines the internal data of the platform and the computer information network can realize data transmission and data sharing; Transmission, etc.;

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

  • Characteristics of TCP/IP protocol

TCP/IP protocol can develop rapidly and become a de facto standard because it just adapts to Worldwide data communications needs. It has the following characteristics: (1) The protocol standard is completely open, can be used by users for free, and is independent of specific computer hardware and operating systems.

(2) It is independent of the network hardware system, can run on the wide area network, and is more suitable for the Internet.

(3) Network addresses are uniformly allocated, and each device and terminal in the network has a unique address.

(4) High-level protocol standardization can provide a variety of reliable network services.
