HOW YOUR PROGRAM ACTUALLY RUNS: FROM C TO CPU

Summary from the TLDR Web Dev newsletter

This article traces how C code transforms from human-readable text into electrical signals your CPU can execute, going through preprocessing, compilation to assembly, binary translation, linking, OS loading, and finally CPU execution via logic gates. At the hardware level, millions of tiny AND, OR, and XOR gates process binary patterns to perform operations like addition, bridging the gap between high-level programming and actual electrical signals.
