excuse me, this is offtopic, i wonder how exactly a binary command of a program translates into a physical action by a machine. put in other words, how do the 0s and 1s of software become impulses of electric current? i would be very grateful if anyone could at least point me to the right sources of info on this.

Great Question. Given what I "know", the electric current is always there, it's motivation is ground. The 1's and 0's determine its path through the semi conductor through the gates of the transistor.

I see , so each binary instruction is a  pattern of passage of electricity through transistors.  Thanks for the pointer, it cleared the picture. Can you also advise what texts or courses in computer science cover these areas?

There is a very good book devoted (more or less) to answering just this question. It is "Code" by Charles Petzold. Highly recommended. http://www.amazon.com/Code-Language-Computer-Hardware-Software/dp/0735611319/ref=sr_1_1?s=books&ie=UTF8&qid=1330274224&sr=1-1
