The purpose of this article is to share with you about the layers of the tcp/ip agreement. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

Tcp/ip protocol consists of four layers, namely: 1, application layer, which provides services for application processes; 2, transport layer; 3, network layer, which can establish and terminate network connections; 4. Network interface layer, which is the physical medium for data transmission.

There are four layers in the TCP/IP protocol.

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

2. Transport layer: as the second layer of TCP/IP protocol, 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.

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

4. Network interface layer: in the TCP/IP protocol, the network interface layer is located in the fourth layer. 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.

These are the layers of the tcp/ip protocol, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
