This article mainly introduces how the TCP/IP protocol is formed, which has certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Tcp/ip is the communication protocol of the Internet. Tcp/ip (Transmission Control Protocol / Internet Protocol) refers to the protocol suite that can realize the transmission of information between different networks, and it is the most basic communication protocol in the use of the network. TCP/IP transport protocol defines the standards and methods of communication in various parts of the Internet.

Correlation

Tcp/ip is the communication protocol of the Internet.

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.

The composition of the TCP/IP protocol:

Four layers in the TCP/IP protocol.

Application layer: the application layer is the first layer of the TCP/IP protocol, which provides services for the application process directly.

(1) for different kinds of applications, they will use different protocols in the application layer according to their own needs. Mail transport applications use SMTP protocols, World wide Web applications use HTTP protocols, and remote login service applications use TELNET protocols.

(2) the application layer can also encrypt, decrypt and format data.

(3) the application layer can establish or disconnect with other nodes, which can fully save network resources.

Transport layer: as the second layer of the TCP/IP protocol, the transport layer plays a mainstay role in the whole TCP/IP protocol. And in the transport layer, TCP and UDP also play a mainstay role.

Network layer: the network layer in the TCP/IP protocol is located in layer 3. In the TCP/IP protocol, the network layer can establish and terminate the network connection and find the IP address and other functions.

Network interface layer: in the TCP/IP protocol, the network interface layer is located in layer 4. Because the network interface layer merges the physical layer and the data link layer, the network interface layer is not only the physical medium for transmitting data, but also provides an accurate line for the network layer.

Features:

TCP/IP protocol can develop rapidly and become a de facto standard, because it just meets the needs of data communication all over the world. It has the following characteristics:

(1) the protocol standard is completely open, can be used by users free of charge, and is independent of specific computer hardware and operating system.

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

(3) the network address is assigned uniformly, and each device and terminal in the network has a unique address.

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

Thank you for reading this article carefully. I hope it will be helpful for everyone to share how the TCP/IP agreement is composed. At the same time, I also hope that you will support us, pay attention to the industry information channel, and find out if you have any problems. Detailed solutions are waiting for you to learn!
