  • • Try the interactive simulators hands-on
  • • Study the pseudocode — it appears in exams
  • • Quiz yourself before moving on

Step 1: Boolean Logic

📖 Theory

Boolean logic is the foundation of all digital computing. It works with just two values: TRUE (1) and FALSE (0).

George Boole developed this mathematical system in the 1800s, and it turned out to be perfect for electronic circuits — a switch can be ON (1) or OFF (0).

Every decision a computer makes, every calculation it performs, ultimately reduces to combinations of Boolean operations on binary values.

🎯 Key Points
  • •Boolean logic uses only two values: TRUE (1) and FALSE (0)
  • •Logic gates are physical implementations of Boolean operations
  • •All computer processing is built from combinations of logic gates
  • •George Boole created the mathematical foundations in the 1800s
  • •You need to know AND, OR, NOT, XOR, NAND, and NOR gates
