How many layers are there in the tcp/ip model? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The TCP/IP protocol refers to the architecture of OSI to some extent. The OSI model has seven layers, including physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer from bottom to top. But this is obviously a bit complicated, so in the TCP/IP protocol, they are reduced to four levels.

The four levels of TCP/IP:

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

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.

The answers to the questions about how many layers there are in the tcp/ip model are shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
