Logic gate , bits and storage

What happens inside a processor at the speed of light? In this installment of our Computer Science series, we move away from high-level algorithms and look at the physical reality of computing. We explore the Bit—the smallest unit of data—and the Logic Gates that turn raw electricity into intelligent decisions. Key Highlights of this Lesson: • The Power of Binary: Why computers use 0 and 1 (On/Off, True/False, High/Low Voltage). • Physical Storage: How bits are actually kept in RAM (electrical charge), Hard Disks (magnetism), and SSDs (trapped electrons). • The Logic Gate Trio: A deep dive into the AND, OR, and NOT gates. • Truth Tables Explained: Learning to predict the output of a circuit based on binary inputs. • Real-World Hardware: How these gates form the basis of security systems, traffic lights, and authentication.
