What literature to read about the principles of PC operation before learning C, C ++, java?

Question

JavaScript

Several times I tried to start learning Java, but as soon as I come across the concepts of encodings, bytes, bitwise operations, bits, machine codes, etc., difficulties begin. Of course Google saves, but these are crutches. I would like to fully understand how a computer works from the inside, how it works, and then start programming.

Answer 1

Although any university textbook will reveal the topic of bytes, bits, encodings and bit operations at a sufficient level to study C, C ++.

Answer 2

It will take a long time to read.
Start with Charles Petzold's "Code", then Tanenbaum's books, and in parallel any textbook on assembler. Should be enough.

Answer 3

mathematics (primarily the logical-combinatorial side, discrete mathematics)
