Logic gates are the most basic components of digital circuits. They are electronic devices that take one or more inputs and produce an output based on the logic of their design. The three primary logic gates are:
When you run a program:
The sequence "logic gates → circuits → processors → compilers → computers" is not a random list but a strict hierarchy of abstraction. Each layer is a complete, useful model that hides the messy complexity of the layer below. A programmer working in Python does not need to think about NAND gates; a circuit designer does not need to think about compiler optimization. Yet, the miracle of modern computing is that all layers operate simultaneously, correctly, and efficiently. Logic gates are the most basic components of
A processor is essentially a massive finite state machine (FSM) built from sequential circuits (registers, program counter) and combinational circuits (ALU, decoders). Each layer is a complete, useful model that
