Key Topics to Revise

1

Binary Logic System

  • Boolean logic is a type of algebra that deals with binary variables and binary operators.
  • Boolean logic was developed by George Boole in the mid-19th century.
  • A binary decision always results in either yes/no or true/false.
2

Truth Tables and Basic Operators

  • Truth tables show all possible input combinations and the corresponding output of a logical expression or Boolean function.
  • The number of rows in a truth table is calculated using 2^n, where n is the total number of Boolean variables.
  • For 2 variables, the number of rows is 4.
3

Logic Gates

  • A gate is an elementary electronic circuit that performs a Boolean function.
  • A gate takes one or more inputs and gives one output.
  • Logic gates work with binary signals, so the output is either 0 or 1.
4

Deterministic and Probabilistic Computing

  • Deterministic computing always gives the same output for the same input.
  • Deterministic computing is well-suited for problems with a single correct answer.
  • Deterministic computing is useful for mathematical calculations, sorting algorithms, and database operations.
