TCP/PI reference model (application layer, transport layer, network layer, network interface layer), five layer reference model (application layer, transport layer, network layer, data link layer, physical layer), OSI and TCP/IP reference model comparison

1. Structure diagram of the TCP/IP, OSI, and five-layer reference models

2. Similarities between TCP/IP and OSI

1. All layers
2. Based on the concept of independent protocol stack
3. Heterogeneous networks can be interconnected

3. Differences between TCP/IP and OSI

4. Five-layer reference model structure

In order to learn the computer network, take a compromise approach, integrated learning OSI and TCP/IP advantages

5. Five-layer reference model data encapsulation and decapsulation (data transmission)
