Discrete Math #25 – Logic Gates: AND, OR, NOT, NAND, NOR

In this lecture, we bridge Boolean algebra with digital hardware by introducing logic gates — the fundamental components of every digital circuit. You’ll learn how Boolean expressions are physically implemented using seven essential logic gates:
AND, OR, NOT, NAND, NOR

We’ll cover:

Each gate’s symbol, truth table, and Boolean expression
The concept of universal gates (NAND & NOR) and how they can construct any circuit
How logic gates form the foundation of CPUs, memory, and digital systems
Whether you're heading into computer engineering, electronics, or logic design, this lecture gives you the hardware-level intuition to bring Boolean expressions to life.
