So let's explain the rules of iptables in a common way. There was an analogy before, Each "chain" is a "checkpoint", Every message passing through this "level" must match the rules on this level. If there is a match, The message is processed correspondingly, For example, you and I are like two "messages" at the moment. Both of you and I are going to enter the customs at this moment. But the duke has a life, Only the imposing person can enter the customs, Those who do not meet this requirement are not allowed to enter the customs. So the soldiers guarding the customs followed the "rules" formulated by the duke. I began to look at you and me. In the end, you entered the customs smoothly, and I was rejected. Because you met the standard of "dignity", you were "released", while I did not meet the standard, so I was not released. In fact, "dignity" is a kind of "matching condition", "release" is a kind of "action", and "matching condition" and "action" form the rules.

Memory, which can be divided into two types: one is called random, which is responsible for temporarily storing data waiting for CPU processing, and the data will be lost after power failure. It has no memory function. If the CPU is compared to the carriage of a train, RAM is the platform, and the people who go up and down the train are the data waiting to be processed and can only stay on the platform temporarily. The other is called read-only device, which can only read but not write, and its contents will not be lost after power failure. We will not introduce all the other equipment in the host computer here. In short, they all perform their respective duties to make the computer run normally, thus making the computer a good helper in our work and life.
