Note: This note is written from a programmatic point of view, which is what I think is helpful for programming, not from the perspective of a network expertise. The following illustration shows the different partitioning of the architecture of the computer: the OSI seven-layer protocol architecture, the architecture of TCP/IP, and the architecture of the five-tier protocol: The following figure illustrates the changes that the application process's

Any tool software has a wealth of features, so in the daily maintenance of internet cafes, for a software, not only to know its surface function, but also to understand its working principle, so as to more effectively mining software more advanced applications and functions, in order to solve the network of difficult problems. The following combined with some of the day-to-day network failure examples, intr

To improve network management efficiency, it is necessary for us to generate a convenient and intuitive network topology map for our local area network in a timely manner. This network topology map is cleverly used, we can quickly find the source of network faults. Now, I wi

A loop problem occurs in the use of wireless networks. Where is the problem? Who is the culprit? The author of this article gives you a detailed description of how to set up your own experience. Unit A subnet has been working normally, but I found that workstations in subnet A recently cannot access the LAN server. After some careful checks, I can see that the new switch devices in subnet A are often unable to connect to the core switches in the LAN. Considering that workstations in other subnet
