At the physical bottom of your computer are transistors—tiny electronic switches that can either block electricity (0) or let it through (1). Alone, a transistor is boring. But wire them together in patterns, and you get logic gates.

These gates are the Lego bricks of computing: logic gates circuits processors compilers and computers pdf

With just these three (plus NAND, NOR, XOR, etc.), you can build anything. At the physical bottom of your computer are

During the ADD instruction:

Thus, a line of C code physically becomes electron flow through silicon. With just these three (plus NAND, NOR, XOR, etc

The Full Adder: Adds three binary digits (A + B + Carry_in).

The Arithmetic Logic Unit (ALU): A complex circuit constructed from adders and logic gates capable of performing addition, subtraction, AND, OR, and comparisons.
