does not do anything to confirm that the packets are sent in order or are not damaged. An IP packet contains the address (source address) of the host that sent the packet and the address (Destination Address) of the host that received the packet ). When receiving data packets, high-level TCP and UDP services generally assume that the source address in the packet is valid. It can also be said that IP addresses form the authentication basis for many services. These services believe that data pack
OSI network layer-7 protocol and its functions OSI is an open reference model for communication between systems. It is a well-defined protocol specification. The OSI model has a layer-7
For more information about the 7-layer structure of the OSI network-Linux general technology-Linux technology and application, see the following. Physical layer is the lowest layer of the OSI
IntroductionOSI (open System interconnect), which is open systems interconnection. Commonly called the OSI Reference Model, is the network interconnection model that the ISO (International Organization for Standardization) organization studied in 1985, which gives you an introduction to the OSI Reference

service for calling application processes. When designing a network application, the application sender must specify one of the two transport protocols. Before a brief introduction of UDP and TCP, we need to first introduce the network layer of the Internet. The Network Layer
Reasons for the existence of the OSI model (open System interconnection):The network model is built so that the builders of the network can build networks that can communicate and work with each other, and describe the transmission of data from one computer to another on a network.1.physical LayerDefines the electronic and functional aspects of the connection bet
Chapter 2 OSI reference model and TCP/IP model (continued)3. TCP/IP model 3.1 the hierarchical network layer of TCP/IP is a key part of the TCP/IP system. Its main function is to enable the host to send information to any network and send it to the correct target. The networ

Through the use of text reading, image viewing, video playback, download transmission, games, chat and other software tools from text, pictures, sound, video and other aspects to bring people a very rich life and good enjoyment. Network Purpose:What is the purpose of network transmission? That's right: data transfer because of the complexity of the network and a variety of
The OSI Layer-7 model is easy to understand and can't be remembered many times. I read it again today and found that it is more logical and easier to remember to look at the problem from the perspective of historical deduction. This article is not necessarily rigorous and may be flawed. It mainly serves to help people with poor memory. In general, the
Introduction: Before 1990, the hierarchical model dominated by data communication and networking literature was the Open Systems Interconnection (open system Interconnection,osi) model, and now the TCP/IP protocol family became the dominant commercial architecture. An OSI seven-lay
In this topic, we will discuss network security from the perspective of OSI hierarchy. We will study the OSI stack in depth from the physical layer to the application layer. Starting from analyzing vulnerabilities at each layer, t

repeater with multiple ports is a hub (for example, if the transmission distance of twisted pair wires is m and the signal length exceeds the whole length, the communication fails. In this case, we need a repeater to expand the signal !).Conclusion: In the osi7 layer protocol, when user a communicates with user B Over FTP, user a first activates port 21 of the application
