Machine code, also known as binary code, is the lowest-level programming language that a computer's processor understands. It consists of a series of binary digits (0s and 1s) that represent instructions, data, and addresses. This code is "hidden" because it is not human-readable and requires a deep understanding of computer architecture and digital logic.
It explains how to combine these gates to perform binary addition and subtraction. Enter by Charles Petzold
