What processes occur at a low level?

I would like to know what is happening at a low level when I drive in the browser console say
var a = 1
what happens in the CPU and RAM and os
there is some chain of logic

or where about it to esteem ?

var_a DW 1

Where var_a - some address in memory
First, DW is a Directive of the assembler, it does not have a corresponding CPU instructions. Secondly, from a specific JS engine and the context variable definition depends on where in memory it will be located on the stack or in the heap. In the second case, the processor instructions may need hundreds. - Zit commented on June 7th 19 at 15:05

The browser console is console Chrome javascript engine V8.
Accordingly, when you write var a = 8 virtual machine javascript using OS allocates a block of memory for the variable.
From OS there are system calls to allocate memory for the processor, etc.
On the hardware level memory is a set of signals 1-0 and the flow continuously passes through the processor, and change is sent back to memory.

Read books on operating systems, architecture of computers, of compilation. Do not to ask what there is a logical chain of people succeed education at the University.

You might be surprised, but most educated in Universities have no idea what is happening there at a low level. - Zit commented on June 7th 19 at 14:59
Wouldn't be surprised, I know how most get their education in high school (well, ie they don'T get it). Don't need to be like the majority (in General obviously), you need to use the UNIVERSITY as possible to get the required instructions and to obtain the desired circle, and it is not possible to get a crust. Maybe you have good friends with a good career, which will explain to you what is useful to know some algorithms and concepts if you do not want to impose landing the rest of my life, but I was not quite the word.

There are people who like all there is and that the UNIVERSITY begin to walk in a continuation school (especially when you do not need to go to another city), and there are stories like mine when higher education is the ability to get out of the city center, where the highest achievement in IT-career - work as a sysadmin at the local branch of Sberbank.

So it is not necessary again about a majority. Most just do not want anything in life except stuffed belly and other attributes of comfortable life. Times TC asks what is going on below the level of JS and it means something else in life bothers. - Breana_Leffl commented on June 7th 19 at 15:02
in universities in the it's already obsolete. And no motivation to study there is not. More useful to spend time on self-education. Isn't it obvious? And they do not try, you will NOT only get an education. In Russia, education has come to an end. You can only physics and mathematics to go, and not everywhere (in physics and mathematics, the self, is a lost cause). - shaun.Ebert commented on June 7th 19 at 15:05
how to build self-education to know where to look for the answer to the question posed by the author? Why he is asking it here and not looking for the answer in Google? - Breana_Leffl commented on June 7th 19 at 15:08
it's an unusual question , the answer to which, however, in the University there. But if you try, it is likely that in Google you can find information about it. Just the author wanted to go the easy route and listen to answers from people who have faced the same question and found the answer. In programming, if not to go into the jungle, you can find answers to almost all questions. And about universities - maybe they have and there are some hardly noticeable advantages, but they are so small that do not justify the time spent. - shaun.Ebert commented on June 7th 19 at 15:11
well that's the problem that why this issue is considered unusual, although it is quite a common. This question is a little more private than the question "how computers work". My point is that some questions are too voluminous to do it to someone you can ask and get any answer. The answer to such questions is a complete education course.
No need to wait on the uni answers as here on the toaster. If that should do the University, so it is first to get to read about things like Turing-complete language, complexity of algorithms, broadcast languages, and THEN to ask such questions, well, or not ask them at all, if you do not need it.
The most important thing that gives the higher education institution is a knowledge and ability to seek knowledge, but not useful right now information. To put it more crudely - the University shows that you really do not know what know would cost. Notice I did not say that most of the knowledge I get from sitting in lectures. I said the author of the question that the training in the University, he will not ask such questions. Will not, because you will already know where to look.

I also don't understand why you think that physics and mathematics, the self, is a bad idea, but IT is not. Maybe just strap requirements for the IT-schnick in the starving market is very low? Well, it's not always be so. - Breana_Leffl commented on June 7th 19 at 15:14

I advise you to listen to an interesting podcast on this subject - https://ru.hexlet.io/blog/posts/podcast_09

To start understanding there is a need to study how the processor, how it works with memory devices in the mother Board, peripheral devices, ACS computer, in General. Assembly language and C, though the corner of his eye, too, is to study together.
Then read a couple of books, how OS works, both in theory and concrete examples of Linux\Windows. All this, at a normal pace, it may take a couple of months, no more.
Further, it will be clear which way Google.
