How does the computer “understand” what the programmer wants from it?

Question

Programming

Good afternoon. I asked myself the question of how the processor understands what to output to the programmer when writing software.
I know that there is an assembler, but the assembler itself is a little bit like a human language.
I roughly understand that the compiler parses the source code and converts it into the necessary codes for the selected language.
But how everything happens exactly at the level of a piece of iron. Is it the dial 010101 0101010 and so on?
What literature to read on this topic.

Start with this How does the processor work at the physical level in the example of adding two numbers (banal 1 + 1)?
