Paper 2 - Computational thinking, algorithms & programming - 2.4 Boolean Logic

infoWhy this? Boolean logic provides a precise way to represent and combine true-or-false conditions in programs and digital circuits. Logic diagrams and truth tables help us explain decisions and verify outcomes systematically.

scheduleWhy now? Earlier use of Boolean operators in selection, iteration, and validation now gains a formal representation through gates and truth tables. This connects programming decisions to the digital hardware explored later in systems architecture.

  • Recognition of each gate symbol for AND, OR and NOT gates.
  • Know the rules for each gate i.e. AND gate - both must be true for output to be true.
  • Truth tables are composed to show all potential outcomes.
  • Multiple gates are combined to create a circuit.
  • How to create a logic diagram from a given expression.
  • The order of precedence.
  • How to create, complete or edit logic diagrams and truth tables for given scenarios.
