I am not a programmer, but I wanted the answer you seem to want.  How
does the damn thing work?  More explicitly:

How does human understandable information get converted by a machine

and/or relocate the data; and then re-present the data as information
meaningful to humans?

I found the answer in "The C Programming Language" by Brian W. Kernighan
and Dennis M. Ritchie.  This book is such a basic that it is often
referred to just as K&R.  If you try to simply use this book as a
tutorial for the C language it is too difficult.  Almost every sentence
contains a new concept.  But K&R and 'C' are closest to the metal.  It's
description and particularly its appendices are used by programmers
mainly as a reference.  It really is a text on how to best write code so
that the compiler can use your 'C' code by translating it into machine
language. It is also, therefore, basic instructions for compiler writers
on how they have writer their compilers.


Sure, how to get this book? Is it available online somewhere?

 
A big however!  I found that when I took my time, and worked each new
concept through, with liberal use of google and some tutorial sites,
with some contemplation on my part, with some reference to the the basic
electrical properties of transistors, capacitors, Direct Current and
crystals, I was able to come to a fairly complete (or at least useful)
understanding of how my computer worked and what the text instructions
that I was imputing were doing.

In addition, I spent a couple of afternoons exploring assembly language
and the IS-32 instruction set.  Looking at how compilers work, and how
they translate your text code into machine code (the '1' and '0's you
mentioned) from libraries makes the need for precise instructions (text
syntax) clear and less of a burden.

I found that by using K&R as a course outline rather than a final all
knowing, all teaching, tutorial book I was able to drill to the bottom
of everything that was happening inside my computer.


That technology is really amazing that whatever in your heart comes, you enter it through keyboard and in a string of '0's and '1's it is read by the processor which then takes the proper action, finally it comes into the wire from where your internet connection is coming (into the form of EM wave of proper frequency, amplitude & time) and then it is further processed! It's really amazing.

 
If you, like me, look for those Eureka! moments in life, you will find
exploring the capabilities of your computer through the 'C' language is
a wonderful voyage of discovery.  The ingenuity and creativity over the
last 50 years that has gone into making the metal, the electricity, and
the programming of a computer is truly a marvel.


Yes, I agree and wonder.

 
If this is the kind of approach that you are interested in respond to
this post, and I will give you some hints and tricks about uncovering
the programming process.  


Please do that, I would love that. It is a fact that I get less time to do this all but I would, as it is of interest and a really cool.

 
If I happen to steer you wrong, I am sure
there are lots of people on this list who will jump in with corrections.

Yes, but I don't think so if it is wrong.
