Where to start learning low-level things?

Question

Programming

In general, I want to understand how low-level things work, like a stack, a heap, how an exe file works, or how a compiler works, etc. I am programming in delphi. Understanding pointers and the like - Yes, I can also read assembler.
Actually, (1) are there any books that describe this? (2) Should I change the language? (I looked in the direction of the pluses, but I didn’t like the language. I also saw Rust, but I didn’t find much in Russian, and it’s not good with English. Assembler - I don’t want to go deep :))

Answer 2

Низкоуровневое - это ассемблер. А С/С++ - язык среднего уровня. А ниже нижнего уровня только архитектура процессора да опкоды, и логические вентили. Думаю вам опкодить тоже нет желания. =)
