What this article shares with you is about the common computer network architectures. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

The common computer network architectures are: 1. The architecture of OSI, that is, the seven-layer protocol of OSI; 2. The architecture of TCP/IP, that is, the four-layer protocol of TCP/IP; 3. The architecture of five-layer protocol.

Computer network architecture

The function of each layer

Application layer: application layer protocols define the rules for communication and interaction between application processes.

Transport layer: the task of the transport layer is to provide general data transfer services for communication between processes in the two hosts.

Network layer: packet segments or user datagrams generated by the transport layer are encapsulated into packets or packets for transmission

Data link layer: IP datagrams handed over from the network layer are assembled into frames and transmitted over the link between two adjacent nodes

Physical layer: using physical media to transmit data in bit form

These are the common computer network architectures, 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.
