Test-network and multimedia

Today we will summarize the knowledge of networks and multimedia.

First, we will show you the overall figure.

1. This part of basic network knowledge is not important. You have not taken any tests in recent years.

2. Concerning the Internet and its applications, IP address division and subnet mask are a difficult issue, because I recently tested a third-level network, and I did not give a detailed summary of all this knowledge, but you must never take it any longer.

3. The knowledge of the OSI Layer-7 model and the TCP/IP protocol cluster is also the focus of this chapter. We must be able to understand the relationships and differences between the layers.

4. multimedia knowledge cannot be considered as a key issue. There are not many questions, but don't take it lightly.

In summary, this is the knowledge of networks and multimedia. Only by comparing graphs with books and real questions can we truly master this knowledge.
