I'm glad you liked my response. But I think AlucardZero's response was fine. If I had seen it, I might not have replied. I'm not a fast typist. I started typing before he posted.

Of course I examined 'man proc' and looked what is available online, but in most cases it remains Greek to me.

When you ask here, someone will probably answer, sometimes more clearly than the man page. Unlike some forums, we don't have too many RTFM fanatics here. But you still would have had your answer faster and in more detail if you took a real look at the man page.
What all the numbered subdirectories are is very clearly answered near the top of the man page.
What a "pseudo-filesystem" might imply is not as obviously explained, which is why I tried to explain the aspect of that which I thought would be most troubling to a beginner. But if you started with the assumption that the developers of Linux know what they are doing, you would tend to get a non troubling estimate of the meaning of things like the proc man page.
There are a lot of Linux man pages that I find worthless. They jump right into obscure details that only an expert could understand without any kind of overview (that might be all a beginner wants or might be what a beginner needs first before the details can be absorbed). But I still check the man page first. Some of them are effective documentation. I think the man page for proc is effective documentation.
