Logic Gates Explained - IGCSE Computer Science (AND, OR, NOT, NAND, NOR, XOR + Truth Tables)

Master all six logic gates for IGCSE / O-Level Computer Science in one clear lesson! We cover what a logic gate is, how to read and build truth tables, Boolean notation, and how to combine gates into a working logic circuit - with exam tips and worked examples. In this lesson: what a logic gate is, binary recap (1 = TRUE/ON, 0 = FALSE/OFF), the NOT, AND, OR, NAND, NOR and XOR gates, truth tables for every gate, Boolean notation, combining gates (Q = A AND NOT B), a real-world burglar-alarm example, and exam tips.
