Computers integrate logic gates, circuits, processors, and compilers to perform a vast array of tasks. A computer system consists of:
The synergy of these components enables computers to process information, communicate, and automate tasks, transforming the way we live, work, and interact.
int add(int a, int b) return a + b;
→ Compiler → RISC‑V/ARM assembly → ADD instruction → ALU made from full adders → XOR/AND gates. The synergy of these components enables computers to
Key Insight: A processor is essentially a massive finite state machine (FSM) built from sequential circuits (registers, program counter) and combinational circuits (ALU, decoders).

At the physical level, a computer is a collection of transistors. A transistor is simply an electronic switch that can either block electricity (0) or let it through (1). By combining these transistors in specific patterns, we create logic gates.
Logic gates are the atomic units of digital computation. They take one or two binary inputs and produce a single binary output based on a boolean function. Key Insight: Amazingly
Key Insight: Amazingly, the NAND gate is functionally complete. You can build any other gate (AND, OR, NOT) using only NAND gates. This means the entire digital universe can be constructed from a single type of primitive.
A single logic gate is useless. When you connect hundreds, thousands, or billions of gates together to perform a specific function, you get a circuit.
