Computer Science — Boolean Logic Complete Pack

Computer Science — Boolean Logic Complete Pack

Master the logic that powers every computer. This complete Boolean Logic pack covers every concept you need — from understanding individual logic gates, through writing and tracing Boolean expressions, to translating real-world problem statements into circuits and truth tables. Clear explanations, exam-focused practice, and real circuit examples throughout.

What's inside:

📘 10.1 Logic Gates

Understand all six logic gates — AND, OR, NOT, NAND, NOR and XOR — with truth tables, Boolean symbols and a full gate reference diagram, laying the foundation for everything that follows.

📘 10.2 The NOT Gate

Explore the inverter in depth — truth tables, double NOT, NOT in combined circuits, and real-world applications including the street lamp and heating system scenarios.

📘 10.3 The AND Gate

Master the AND gate — two and three-input truth tables, AND with NOT inputs, AND in multi-gate circuits, and applied Boolean design tasks including safety-critical scenarios.

📘 10.4 The OR Gate

Build confidence with the OR gate — truth tables, OR vs AND comparison, OR in combined circuits, NOR equivalence, and real-world alarm and access control design.

📘 10.5 The NAND Gate

Understand why NAND is the universal gate — truth tables, NAND as NOT, NAND as AND, NAND as OR using De Morgan's Law, and chip manufacturing advantages.

📘 10.6 The NOR Gate

Explore NOR universality — truth tables, NOR as NOT, NOR as OR, NOR as AND, De Morgan's Law, and comparison with NAND as the symmetric universal gate.

📘 10.7 The XOR Gate

Master the exclusive OR gate — truth tables, XOR vs OR comparison, the half adder circuit, parity checking, equality comparison, and XOR encryption and decryption.

📘 10.8 Logic Expressions

Read, write and evaluate Boolean expressions — operator notation, precedence (brackets → NOT → AND → OR), De Morgan's Laws, Boolean identities, and simplification.

📘 10.9 Representing Truth Tables

Construct truth tables for any circuit — the 2ⁿ row formula, input ordering, intermediate columns, multi-gate traces, identifying gates from output columns, and circuit verification.

📘 10.10 Representing Logic Expressions

Translate between circuits and expressions — trace tables for complex circuits, describing circuits from expressions, circuit equivalence proofs, and De Morgan applied to physical circuits.

📘 10.11 Representing Problem Statements

Translate real-world problems into Boolean logic — key word mapping (both/either/not), the 4-step translation method, multi-condition systems, truth table verification, and applied design tasks.
