The correspondence between the Isoosi reference model and the layers in the TCPIP protocol model

Iso/osi the PDU (Protocol Data unit) corresponding to the TCP/IP protocol model of the Reference Model
The application layer ..... ..... The application layer ...... Data
The presentation layer ..... ..... The application layer ...... Data
The session layer ..... ..... The application layer ...... Data

The transport layer ..... ..... The transport layer ...... Paragraph

The network layer ..... ..... The Internet layer ... Package

Data link layer ..... Network interface layer ... Frame
The physical layer ..... ..... Network interface layer ... Bit stream

Iso/osi Reference Model and TCP/IP protocol model
The same point: 1, there are application layer, transport layer, network layer.
2, are the upper layer of services.

Different points: 1, the number of layers is different.
2, the model and protocol appear in different order, TCP/IP first protocol, after the model (out
is early), Iso/osi first has the model, then has the agreement (appears late).
